FOR RETURN VALVE V2A
Product No.: 050000264

FKM 75 ETP is a special type of fluorinated rubber (FKM) developed for extreme chemical and thermal requirements. The designation ‘ETP’ stands for Extreme Temperature and Performance, and this material belongs to the Viton® polymer family manufactured by Chemours.

?? Properties of FKM 75 ETP
- Hardness: 75 Shore A – medium elasticity, good for seals
- 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
- Good ozone and weather resistance
