Real Life Experience at Anderson Development Company

Do you remember what it was like when you were in high school or college and you were trying to figure out what you wanted to be when you graduated? Do you remember thinking you knew what you wanted to do but just wasn’t sure? This is probably the case with most high school and college students. The only way to really find out if a particular career is something you’re interested in pursuing is to try that career out. One way to do that is through an internship or co-op experience.

Here at Anderson Development Company (ADC), we welcome interns and co-ops to local students or students who attend local College and Universities. Anderson Development Company partners with local colleges to get interns to work as an Engineer Co-op, in our Research and Development Labs, or newly added Environmental Group internship.

Here’s what a couple interns had to say about their current intern experience at ADC:

Better Products Start in Adrian with Anderson Development

Anderson Development Company (ADC) is a chemical manufacturing facility that produces specialty and custom chemical products. It is often hard for those in our community to understand exactly what we do here since we don’t make something people see on a store shelf with our name on it.

We actually do a lot of really interesting things here at ADC. Many may not realize that our Almatex® acrylic resin goes to a coating company and then to a wheel company and then to the auto makers. Most likely when a person buys a new car, the resin on the wheels probably came from ADC.

Our Almabor® products go into a wide variety of applications such as pharmaceutical drugs or silly putty! We also make products that make tougher roller coaster wheels, and ketchup or sauce bottles to keep the contents fresh. ADC also has a new opportunity on the horizon making products that is used to make a specialty ink for flexible packaging such as potato chip bags.

Even though our name not be on the shelf in your favorite grocery store, or on a billboard somewhere…our products are making other products better all around the world! Better products start in Adrian with Anderson Development Company!

GHS Implementation at Anderson Development Company (ADC)

What is GHS?

The GHS is an acronym for The Globally Harmonized System of Classification and Labeling Chemicals. It was created by the United Nations and designed to replace diverse classifications and labeling practices used in different countries with a consistent and universal criteria that can be used on a global level. GHS is not mandatory and countries are allowed to adopt only portions of it. Therefore we already see the lack of truly global harmonization. You can learn more about GHS at www.unece.org.

Is GHS applicable to the USA?

Yes it is. In 2012, the U.S. Occupational Safety and Health Administration (OSHA) published the new Hazard Communication Standard 2012 (29 CFR 1900.1200) that is aligned with GHS. Consequently, OSHA will now require one standardized format for safety data sheets (SDSs) and set wording and hazard symbols on labels. The new standard is classification based. It includes specific criteria for classification of health and physical hazards. As with the old standard, HazCom 2012 does not apply to consumer products. You can learn more about it at www.osha.gov.

How does it affect ADC?

ADC, as a chemical manufacturer, is committed to complying with the requirements of HazCom 2012 and will ensure compliance by OSHA’s deadline of June 1, 2015. The new HazCom 2012 will result in changes to ADC’s SDSs and industrial hazard warning labels. The changes will only be a consequence of being compliant to the OSHA rules and not alterations to current product formulations or manufacturing processes. ADC will phase in compliant SDSs and labels over a period of time. We have started the process as we have been working on updating our SDS and labels. You can expect to see soon that the ADC’s labels and SDSs may feature new pictograms, hazard determination and safety information. Perhaps most noticeable change will be in the addition of pictograms, but expect changes in hazard classifications also. We will provide our customers with new copies of SDS as soon as the process is complete. The updated SDS will also become available on our website. We are dedicated to make the required changes by June 1st, 2015.

If you have further questions please contact your sales or customer service representative, or submit your inquiry online to sds@anddev.com.

Boron’s Compounding Value

Boron as an element is by no means a major contributor to the Earth’s mass. This is somewhat surprising given the variety of uses boron possesses and how it plays an important role in some of today’s most vital operationsand economies. The applications of boron in organic chemistry are really impressive and it is beyond the scope of this publication to cover them in detail. However, some of them are worth highlighting to demonstrate the significance of this element in many diverse fields.

Importantly, while boron maintains some characteristics with its neighbors on the periodic table (carbon and silicon), it is chemically distinct, and this distinction is what enables its broad utility. Over many years chemists took advantage of boron’s chemical usefulness and many new applications involving its use have been developed. Boron, since its isolation in 1808, has continued to be a popular subject of study. The discovery of pyrophoric triethylborane by Frankland in 1859 marks the beginning of the chemistry of organoboron compounds. Triethylborane is known to be readily oxidized in air to diethylborinic acid; and further by a second, much slower oxidation step, to a more stable and crystalline ethylboronic acid. This sequence is the first known synthesis of boronic acids. The next major advance in boron chemistry dates back to 1926 when borazine (known as “inorganic benzene”) was synthesized for the first time by Stock and Pohland. Many new developments in boron-based reagents came from work during the World War II due to increased interest in using diborane in vaporizing uranium. This era marks the discovery of two contrasting reducing agents (NaBH4 and LiBH4) as well. A breakthrough for boron’s advancement was the discovery of hydroboration of alkenes by H. C. Brown in the mid 1950’s. His work has increased the level of interest in organoboron compounds and their applications. Tri-coordinate organoboron compounds have proven to be an important class of molecules as they can be used not only in synthetic applications but also as advanced materials, for example in Organic Light Emitting Devices. Boron binds easily with halogens (with the exception of iodine) to form an important class of compounds as well. The heavier the halogen the more aggressive the Lewis acid is. On the other hand, the more ionic character of the boron-halogen bond, the less stable bond. Naturally occurring boron comprises of two isotopes (the 11B 80.22% and 10B 19.78%). The 10B isotope has a high neutron absorption cross section that is exploited in nuclear reactors to control neutron flux. When 10B captures a neutron, a nuclear reaction occurs 10B(n,a)7Li ejecting an alpha particle. This characteristic has been exploited in Boron Neutron Capture Therapy (BNCT), an area of active research for boron chemists for several decades, for treatments of a  variety of aggressive cancers, often those found in the brain.

When one thinks about the utility of boron, the Suzuki-Miyaura cross coupling reaction typically comes to mind. It is a very valuable synthetic reaction that was developed in late 1970’s and because it wasn’t patented is nowadays one of the most common carbon-carbon bond forming methods in organic synthesis. The Suzuki-Miyaura reaction brought boronic acids and esters, the main reaction precursors, into the spotlight. From the 1970s onward the demand for boronic acids has increased dramatically ultimately driving the development of new, more economically feasible synthetic methods and applications for both their preparation and their uses. Low molecular weight boronic acids have found many diverse applications due to their electronic and physicochemical properties as well. They have been developed as enzyme inhibitors, drug carriers and sugar sensing agents.

Standard routes for the preparation of boronic acids involve utilization of Grignard- or lithiated reagents with trialkyl borates. Frequently, commercially available reagents such as: trimethyl borate or triisopropyl borate have been exploited in this reaction. Although most boronic acids are crystalline solids and can be handled in the presence of air or moisture, they are prone to dehydration and formation of oligomeric anhydrides such as the trimeric boroxines. The organoboronic acid esters (boronates), on the other hand, are less polar and easier to handle due to the hydroxyl groups being masked. The ester moiety serves as a protecting group which at the same time alleviates the reactivity of the boron-carbon bond. The bulkier the ester moiety the more stable the molecule is. Therefore the cyclic esters such as pinacol have been recently utilized in many applications. The most common way to prepare boronates is by reaction of the pre-isolated boronic acid with the alcohols or diols (Scheme 1).

 Drawing of Aryl Boronates Scheme

Scheme 1 Synthesis of Aryl Boronates

There also exists a possibility to transesterify smaller dialkyl esters like a methyl ester with bulkier alcohols or 1,2-diols. Usually cyclic boronates are prepared from the more air-sensitive or less stable boronic acids and 1,2-diols, such as catechol or pinacol, as they exhibit slower rates of proto-deboronation when compared to the corresponding boronic acids. An alternative route, though often more expensive, involves transition metal catalysis with appropriate tetraalkoxydiboron or dialkoxyborane reagents such as bis(pinacolato)diboron or the corresponding pinacolborane. These reagents are presently commercially available which accounts for their applications being prevalent in the literature. There is a new trend to use newly commercially available cyclic borates (Scheme 2) such as dioxaborinanes (six-member ring framework) and dioxaborolanes (five-member ring framework) with Grignard- or lithiated reagents for the synthesis of their corresponding organoboronates. The reaction does not require cryogenic conditions and proceeds well even on larger scales.

Drawing of Cyclic Organoborates Scheme

Scheme 2 Cyclic Organoborates

More stable than cyclic organoboronates are the organotrifluoroborate salts. This class of organoboron compounds has utility due to high carbon-boron bond stability towards oxidation, protodeboronation and nucleophilic attack. The ease of their preparation, purification and long- term storage makes them valuable reagents in organic synthesis. In addition to Suzuki-Miyaura coupling, potassium organotrifluoroborates participate in a variety of other useful reactions including: 1,2- and 1,4-addition, C—O and C—N bond formation, halogenation and allylation reactions.

Velcade Chemical Structure Drawing

Increasing attention in boron chemistry has been invigorated by the recent US FDA approval of a boron-containing peptidic proteosome inhibitor, bortezomib (Velcade), indicated for multiple myeloma and mantle cell lymphoma. Bortezomib contains a boronic acid moiety which is crucial to its mechanism of action. The interest of exploring boron containing therapeutics is also driven by the unique electronic properties of boron, which allow it to act as a transition-state mimetic for the tetrahedral intermediate of peptide bond cleavage observed in proteolytic enzymes. Currently several other boron-containing molecules are in the preclinical and clinical stages of development to treat multiple disease conditions, such as inflammation, diabetes and cancer. For example, the benzoxaboroles, a class of compounds wherein the boron atom is incorporated into a heteroaromatic ring system, have provided a number of interesting anti-inflammatory, antifungal and antibacterial properties according to recent research. So why do we not have more boron-containing drugs? The main reasons for it are: boron toxicity that was initially incorrectly believed to be very high among many medicinal researchers coupled to not having enough synthetic tools to introduce the boron into the molecules. The recent development of many new synthetic methodologies allows medicinal chemists to more easily design drug-like boron containing molecules and explore their properties. Furthermore, as research shows on the Velcade example, the toxicity of the boron-containing molecule does not come from boron itself but from the drug’s mechanism of action. There is overwhelming data for the safety of boron. Boric acid has a LD50 of 2660 mg/kg (rat, oral) which is almost as high as regular table salt at 3000 mg/kg (rat, oral). Boron is found in fruits, vegetables and it is considered an essential plant nutrient. Boric acid is used in eye wash solution and many creams as well. It would rather plainly appear that the human body knows how to safely and effectively deal with boron. So the question to focus on now is not what happens to boron in the human body but what happens to the rest of the drug’s molecule when the boron is cleaved off and where does the entire molecule also interact while boron is intact, much like any other typical drug candidate.

Relative to other elements like carbon, nitrogen, hydrogen or oxygen, the chemistry community is still in a process of exploring the benefits of boron in many different fields. As mentioned above, the unique properties of boron (chemical, physical and biological) offer an interesting opportunity to investigate new areas of application. Moreover, environmentally friendly and relatively inexpensive raw materials incorporating boron can be easily utilized to build high value product. Feel free to contact us today to explore how you can begin utilizing organoboron compounds in your chemical endeavors to further amplify your business efforts!

Choosing the Right Material for the Job

Choosing the right polyurethane product for your application can be an overwhelming process. With so many different types of applications, practically no two applications are the same. The trick is to figure out what material properties are the most important, while at the same time keeping price and processability in mind.

Polyurethane (PU) elastomers are most often used because of their overall toughness, especially when it comes to abrasion resistance. Other advantages include high cut-and-tear resistance, good dynamic performance under load (low hysteresis), and ease of processing. PU is also very versatile in what type of material form it can take. Various formulations can achieve very low durometer (hardness), similar to a soft rubber or silicone material, while others can be cast as very hard material like nylon. At Anderson Development, we optimize PU properties such as compression set, resilience, abrasion resistance, flex fatigue, load bearing capability, solvent resistance, hydrolysis resistance,  thermal stability, and UV stability to name a few.

Below is a table with general property info for a given type of polyurethane system.

Polyurethane Description General Attributes
Aromatic Isocyanate/Polyester Backbone Excellent physical properties, excellent abrasion resistance, good solvent resistance
Aromatic Isocyanate/PTMEG Polyether Backbone High resilience, excellent dynamic performance, great physical properties, good abrasion resistance, great hydrolytic stability, excellent low temperature flexibility
Aromatic Isocyanate/PPG Polyether Backbone Good physical properties, low viscosity (easier to process), great hydrolytic stability
Aliphatic Isocyanate/Polyether Backbone Great physical properties, excellent thermal stability, excellent light stability
Specialty Isocyanate/Polyether or Polyester Ultimate toughness with excellent physicals for very demanding applications

Below are a few example applications in which cast PU has excelled and an explanation of why the properties of a particular PU system make it the right choice.

V-rollers

V-roller

V-rollers need load bearing capabilities and low hysteresis in order to succeed and PTMEG-based cast polyurethane offers both of these properties.  In addition, cast polyurethane can be formulated for low compression set. When a load is placed on a stationary roller for a period of time it will resist forming a flat spot, so that when it starts to rotate again, the motion will be smooth. In high speed applications, the low hysteresis (low heat buildup) of the polyurethane allows it to run faster without getting so hot that it deforms from internal melting. The high resilience, or rebound and low tan delta, which is a measure of energy absorption, shows that a PTMEG-based material will perform well dynamically.

Seals/Gaskets

Cast polyurethane makes a good material for seals because of its versatility. Seals can be soft (40-50 Shore A) or a little bit more rigid (95 Shore A or higher), depending on the stress that is put on the seal or gasket. It is critical to have a good compression set so that the seal won’t take a set when the stress is relieved and will keep a tight seal. Good flex fatigue and hysteresis may also be an important property if the seal or gasket is being flexed or compressed cyclically.  Also, depending on what type of fluid (gas or liquid) the seal is containing and the temperature of the application, a specific type of urethane might need to be used.

For applications that need a soft, tough urethane, a polyester urethane is typically used, especially in situations with exposure to oil or solvents, as is often the case with seals and gaskets.  A polyester polyurethane has excellent flex fatigue, too.  In the case where the fluid is air or a water-based material, a polyether polyurethane should be used.

Bumpers

The key for a good bumper pad is resilience and toughness.  The bumper is ultimately a buffer between two surfaces or objects.  A high resilience, or rebound material, results in a bouncy material so that when the pad is bumped, the energy is deflected.  On the other end of the spectrum is a low rebound material in which the energy is absorbed, similar to a dead blow hammer. Cast polyurethane can have high or low rebound.

Scraper blades

Scraper blades, which are used in many different industries for cleaning and scraping a belt or other objects, see a lot of abrasion and wear and that why cast PU is used. With its great abrasion resistance, cast PU outperforms other materials such as steel and rubber – and less down-time means higher productivity.

While there is usually a polyurethane type that will work for every application, the material does have its limits. In temperatures above 150°C, hot environments with humidity, or exposure to glycols or amines, materials other than polyurethane should be considered.

A Better World through Chemistry

EarthChemical Companies Misunderstood

In today’s modern world, chemical companies are often viewed in a harsh, negative light. Many of these negative perceptions were created in the late 1980s and early 1990s, when public distrust of chemical companies was at an all-time high. In 1965, 55% of the public held a favorable opinion of chemical companies. By 1990, this changed to only 14% (Chemical Manufacturers Association report).

In the twenty-plus years following this statistic, things have changed in the chemical manufacturing
industry. The implementation of the Responsible Care® program by American Chemistry Council (ACC) members has greatly improved environmental, health, safety, and security performance of the chemical manufacturing industry. Responsible Care® is a global initiative, currently used by 53 national associations, with the goal of promoting the safe and secure management of chemicals, products, and processes.

Many chemical companies, such as Anderson Development Company, are compliant with all necessary rules and regulations. We strive to continually improve our processes, limit waste, and be as economical as possible. We produce high quality material with our end-user always in mind.
