- Temperature range: approx. –15°C to +220°C
- Chemical resistance:
- Excellent resistance to ketones, esters, aldehydes
- Resistant to aggressive acids, amines and hot water
- Similar in performance to FFKM (perfluoroelastomers), but less expensive
- Processing: Peroxide-cured for improved thermal stability
?? Typical applications
- Oil and gas industry
- Aerospace
- Automotive
- Chemical industry (e.g. paints, solvents)
?? Special features
- Remains flexible at low temperatures
- Low compression set – ideal for long-lasting seals
