Many polymers naturally occurring, such as silk, cellulose, natural rubber and proteins. In addition, a large number of polymers have been synthesized in the laboratory, leading to such commercially important products as plastics, synthetic fibres and synthetic rubber. Polymerization, the chemical process of forming polymers from their component monomers, is often a complex process that may be initiated or sustained by heat, pressure, or the presence of one or more catalysts.
There are organic and synthetic polymers. Examples of organic polymers are AO Cellulose, natural rubber, proteins and silk. Examples of synthetic polymers are Kevlar, Kynar, Neoprene, Nylon, Teflon and Viton.
There are many variations in the chemical composition of polymers, such as structure and chain. Additives determine the composition of the polymer. When pumping polymers the most important issue is the pump action itself. A polymer pump must handle the polymer with a smooth and sensitive pump action, avoiding shaking and wild fluid movements. Polymers are of very tough and adhesive structure and many volumetric pumps may cause damage. Verderair double diaphragm pumps ensure that the chain structure of the polymers is maintained as the pump action is of a gentle nature.
