Polymer
chemistry is the backbone of our business. By carefully matching the
customer's needs with our polymer technology, the optimum sealing
solution for both performance and economy can be chosen.
Selecting
An Elastomer Seal By first understanding the basic chemical alternatives and properties, the selection process is simplified.
Types
of Polymers There are three types of polymers - Thermoplastics, Thermosets and Elastomers.

Nitrile(Buna-n) O-rings Nitrile(buna n) is a copolymer of butadiene and acrylonitrile, a compound that is commonly used in o-rings.
FEP/PFA
Encapsulated O-rings FEP and PFA are actually not elastomers, they are a plastic. Our FEP/PFA encapsulated o-rings consist of a seamless FEP/PFA jacket over an polymer core made from Viton® or silicone.
Neoprene O-rings The name neoprene refers to a whole a group of synthetic rubbers that are produced by the polymerization of chloroprene.
