Viton Rubber (FKM)
Excellent resistance to high temperatures, chemicals and oils for extreme applications
View SpecificationsViton Rubber (Fluoroelastomer FKM)
Viton Rubber (FKM - Fluoroelastomer) is a high-performance elastomer recognized for its exceptional resistance to extreme temperatures, aggressive chemicals, oils and fuels.
With an operating temperature range in oil from -20°C to 250°C and excellent chemical resistance, Viton is the ideal material for applications where other elastomers would fail under severe conditions.
High-Performance Properties
Viton Rubber stands out for its unique properties for extreme applications:
- Exceptional resistance to high temperatures up to 250°C in oil
- Excellent chemical resistance to acids, alkalis and aggressive products
- Superior resistance to oils, fats and hydrocarbons
- Excellent ozone and weathering resistance
- Low compression set (15% maximum)
- Excellent aging resistance
These properties make it indispensable in aerospace, automotive, chemical, petroleum industries, and any application requiring maximum reliability under severe conditions.
