Rubber FKM

It is considered the most premium rubber. It performs up to 10 times better than rubbers such as NBR rubber. This synthetic fkm rubber has exceptional chemical resistance, and high temperature

Excellent oil and chemical resistance and flame resistance. It possesses low permanent compression set deformation.

However, viton use is not recommended in the presence of certain chemicals such as low molecular weight esters and ethers, ketones and amines.

It is mainly used as a sealing material where exceptional service capabilities and durability are required under both moderate and severe operating conditions. Viton is therefore most suitable for variable or unfamiliar operating conditions and where operational safety is particularly critical.

It is particularly suitable for the oil, chemical and pharmaceutical industries.
