FKM rubber (fluororubber), also known under the brand name Viton registered by DuPont, is a high-quality elastomer that is characterized by its exceptional chemical and thermal resistance. Molded rubber parts made of FKM are indispensable in demanding environments where reliability and durability are required.

Properties of FKM rubber

• Chemical resistance: FKM resists aggressive substances such as oils, acids, bases and fuels
• Temperature resistance: Can be used from -20 °C to +200 °C (in some cases up to +250 °C).
• Mechanical robustness: High elasticity, abrasion resistance and low gas permeability.
• Weather resistance: UV, ozone and ageing resistant, ideal for outdoor applications.
• Impact elasticity: Very low, 5-10%
• Hardness range: 50-95 Shore A

Thanks to these properties, FKM rubber molded parts remain efficient and durable even under extreme conditions.

Advantages of FKM rubber

• Durability: Minimizes maintenance costs thanks to high durability.
• Adaptability: Individual production in various shapes, colors and degrees of hardness.
• Conformity to standards: Many formulations are FDA or ISO-certified, suitable for food and medical technology.

Molded rubber parts made of FKM rubber are the first choice for applications under extreme chemical and thermal conditions. The production of moulded rubber parts requires a highly specialized process in which precisely matched rubber compounds are inserted into custom-made metal moulds. Processes such as pressing or injection moulding are not only used to precisely implement the desired shape, but the chemical cross-linking during vulcanization also ensures the necessary stability and the characteristic elastic properties of the material.

Thanks to these manufacturing methods, molded rubber parts made of FKM can be produced with precise geometry and outstanding mechanical properties, which are indispensable for a wide range of applications.
