Fluorocarbon elastomers automotive applications

Fluoroelastomers. The fluoroelastomers were introduced to the mbber industry in the late 1950s by the DuPont Company. They were made by modification of Teflon polymers and designed to have excellent heat and chemical resistance, but remain elastomeric in nature. They were very expensive and have found use in limited applications. However, with the increasing demand in the automotive and industrial market for improved reliability and longer life, the elastomeric fluoroelastomers have made significant inroads into these applications (see Elastomers, synthetic-fluorocarbon elastomers). ... 

Consumption in Europe and Japan depends more upon the automotive industry. However, with the recent concern about acid rain, the European market is expected to show increased interest in fluorocarbon elastomers for pollution-control applications. In Japan, fluorocarbon elastomers are used for general manufacturing, eg, copiers. Petroleum applications are of little interest outside the United States. The aircraft industry uses less than 10% of the total fluorocarbon elastomer consumed. 

MAJOR APPLICATIONS Antifoam fluids, lubricants, protective gels, and elastomers and sealants in applications exposed to hydrocarbon fuels and oils and organic solvents in the automotive and aerospace industries. Longer fluorocarbon side-chain fluorosilicones are available with developing use as release coatings for silicone-based adhesives.
