Plastics also cause many waste problems. Polymers are not as toxic to people as the monomers they contain. But when cut, heated, or manipulated, polymers and their byproducts can release dangerous dust and vapors. Vinyl acetate in EVA may affect the heart, nervous system, and liver. Most polymers are safe and non-toxic. The monomers that are used to make polymers, though, are often toxic or stinky. Begin typing your search term above and press enter to search.

These applications can be as varied as the polymeric materials used in medical devices, pharmaceuticals, food and beverage packaging, and personal care cosmetics.
They are made from repeating chains of bonded molecules that are typically organic but, in some cases, may even be inorganic in nature. Natural rubber is a polymer consisting of the simple hydrocarbon isoprene, while polyethylene PE is a synthetic plastic manufactured from ethylene monomers. A typical polyethylene may consist of up to , monomers, the composition, and concentration of which can have a significant impact on the qualities of the end-product.
Polymerization is the process that causes small molecule monomers to covalently bind with one another and form tough interlinking polymer chains. The polymer chain can be formed using a range of chemical species by heating or pressurizing samples in the presence of catalyzing agents.
An assortment of engineering techniques is used to manufacture polymers with varying molecular weights and chemical-mechanical properties. For example, some epoxy resins are made through copolymerization with an amine, a process in which the polymer reacts with a hardener to form the final product.
