Fluorocarbon rubbers (VITON):
Fluorocarbon rubbers are typically produced as a copolymer of vinylidene fluoride, and are used as a high cost and high quality synthetic rubber. Marketed products include Viton from Dupont and Fluorel from 3M. These materials have excellent resistance against heat, chemical products, oils, and solvents.
The compound is still able to retain at least 1/2 of its various properties after 16 hours exposure to 220oF. The compound also has excellent low temperature stability, allowing applications at temperatures as low as -40oF.
The use of additives will greatly improve tensile strength, but low temperature extensibility may be slightly compromised. Excellent resistance against oxidation, ozone, and fires. Hardness of conventional formulations
Hardness between 65 to 95 (Shore A). Other types of formulations are available as well.
Vulnerable to erosions by chemical fluids such as ketones, combined amines, anhydrous ammonia, and skydrol. Strengthening is required to obtain better quality. Products are mainly used as sealants, plates, membranes, pump impellers, pipelines, and equipment exposed to extreme vacuum or EM radiation.
