Riordan Manufacturing, Inc. an industry leader in the field of plastic injection molding was founded by Dr. Riordan, a professor of chemistry in 1991. The company is now an “industry leader in the field of plastic injection molding” (Riordan, 2008). They have state-of-the-art design capabilities and created innovative plastic designs that have earned international…
The company, founded by Dr. Riordan, is wholly owned by Riordan Industries. Dr. Riordan, a professor of chemistry, obtained several patents relative to plastics, and foreseeing the commercial applications, he started the company in 1991 (Apollo Group, Inc., 2013).…

The first urethane was synthesised, by this route, as early as 1849 by Wurtz. In 1937, following very systematic and intensive research works at IG Farbenindustrie, in Germany, Dr. Otto Bayer synthesised the first polyurethane, by the reaction of a diisocyanate with a polyester having two terminal hydroxyl groups (called polyester diol, in fact an α,ω−telechelic polymer with terminal hydroxyl groups) (Mihail Ionescu, 2011):…
There are two plants that produce polypropylene for Victoria Chemicals. The two plants are located in Liverpool, England, and Rotterdam, Holland. The plants were built in 1967 and are identical in scale and design. These two plants supply Victoria Chemicals’ European and Middle Eastern customers. It has been estimated that there are seven major competitors of Victoria Chemicals in its market region (Exhibit 1) and numerous small producers.…
Blending smooth white sap known as latex from the indigenous Hevea brasiliensis trees (later called Para elastic trees) with juices from the morning eminence vines, they could make a strong that was, shockingly, very durable. The human advancements utilized this old elastic for an assortment of purposes, from shoes to balls to adornments. Truth be told, while Charles Goodyear is for the most part credited with the innovation of vulcanized elastic (a more sturdy and non-sticky elastic compound by means of the expansion of sulfur and warmth), it appears that the Aztecs were basically changing the fixing extents (between the latex and the morning greatness juice) to make distinctive varieties in strength. There is by all accounts clashing reports on whether Hancock had built up the vulcanization procedure freely of Goodyear or if, the same number of claim, that he had procured an example of Goodyear vulcanized elastic and built up a slight minor departure from the procedure. In any case, Hancock's patent halted Goodyear from having the capacity to patent his procedure in England.…
Everyday thousands of people undergo some sort of medical or dental procedure during which they have some sort of material implanted into their bodies. Yet, most people do not give much thought as to what materials are being implanted, and how they may react with the body. One perfect example of this would be having a cavity filled. In today¡¯s society dentists use various different materials and methods to fill cavities. Yet, the oldest and perhaps most effective is dental amalgam.…
DuPont is an American chemical company headquartered out of Wilmington, Delaware. “DuPont provides a wide range of products and services for markets including agriculture, nutrition, electronics, communications, safety and protection, home and construction, transportation and apparel. One such product is Kevlar®, which is DuPont 's registered trademark for a very light, very strong synthetic fiber that is spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar® belongs to a class of synthetic polymer fibers known as aramids…highly resistant to heat, and has a strength-to-weight ratio that is approximately five times stronger than steel.” (VIRGINIA) The production procedure of these items are considered trade secrets, and requires all employees involved with the selling or production of such items to sign non-disclosure agreements.…

Dr. Baekeland had originally set out to find a replacement for shellac, made from the excretion of lac bugs. Chemists had begun to recognize that many natural resins and fibres were polymers, and Baekeland investigated the reactions of phenol and formaldehyde. He first produced a soluble phenol-formaldehyde shellac called "Novolak" that never became a market success, then turned to developing a binder for asbestos which, at that time, was molded with rubber. By controlling the pressure and temperature applied to phenol and formaldehyde, he produced a hard moldable material and patented in 1907 known as Bakelite.[2][3] It was the first synthetic thermosetting plastic ever made. It was often referred to as "the material of 1000 uses", a phrase originated by Baekeland himself.[4] He announced the invention at a meeting of the American Chemical Society on February 5, 1909.…
