Rubber Gaskets
Rubber gaskets are renowned for their compressibility, which allows them to fit tightly into the spaces for which they are designed and therefore preventing any leaks. The compressibility of a rubber gasket is measured using a number of tests, the most common being the hot compression test.
Rubber gaskets are commonly produced by cutting rubber sheet materials. In addition to natural rubber, many synthetic rubbers are used to make gaskets. When in contact with petroleum products, the synthetics neoprene, viton, and nitril (NBR) are often used. TPEs (thermoplastic elastomers), also known as TPRs (thermoplastic rubbers) are rubbers that are processed like plastics and used in a number of gaskets and seals. PVC (polyvinyl chloride) is a versatile synthetic with excellent resistance to chemicals and weathering.
Rubber gaskets are commonly used in heavy equipment, appliances, construction, HVAC applications, and transportation industries.
