Rubber Viton, Viton, FKM, FPMis a brand of fluoroelastomer owned by DuPont, Viton is considered the best fluoroelastomer available today. Based on fluoroelastomer, a rubber compound is made, from which the part is then made. In accordance with various standardization systems, the phrase "fluoroelastomer" is denoted by various abbreviations, but the meaning of this and the material itself do not change.

AbbreviationFPM- in accordance with the guidelines of the International Organization for Standardization (ISO), abbreviation FKM - in accordance with the designation adopted by the American Society for Testing and Materials (ASTM). Those. FPM is the international name and FKM is the American name for the same material. In Russia, the abbreviation is accepted - FK.

Viton /FPM /FKM /VITON (Fluoro rubber)- has high chemical resistance, as well as resistance to elevated temperatures. It has excellent mechanical and physical properties, the content of fluorine in the rubber compound ensures the incombustibility of this material. Fluoroelastomers have low gas transmission and minimal weight loss when operating in vacuum.
