Fluoroelastomer (FKM - Viton®, Fluorel®, etc.) is range of fluoropolymer elastomers whose formulation can be tailored to a reasonable extent to meet the needs of individual end-uses. They are normally black and have high heat, oil and chemical resistance but indifferent low temperature performance. With the exception of Kalrez® perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers. Trade names include Viton® (DuPont Dow Elastomers), Fluorel® & AflasTM (3M Corporation), and Technoflon® (Montedison). Products & Services
