Viton rubber

Viton rubber (fluororubber)

Rubber Viton, Viton, FKM, FPM is the brand of fluororubber owned by DuPont, to date, of all existing fluorocouples, Viton is considered the best. On the basis of fluororubber rubber compound is made, from which, then make the part. In accordance with various standardization systems, the phrase "fluororubber" is denoted by different abbreviations, but the meaning of this and the material itself does not change.

The abbreviation FPM is in accordance with the guidelines of the International Organization for Standardization (ISO), the abbreviation FKM is 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 FC.

Viton /FPM /FKM /VITON (Fluoroelastomer) - has a high chemical resistance, as well as resistance to elevated temperature. It has excellent mechanical and physical properties, the content of fluorine in the rubber mixture ensures the incombustibility of this material. Fluoride elastomers have a slight gas transmission and minimal weight loss when working in a vacuum.
