KATON®5000 SERIES O-RINGS
 
Temperature Range: -5°C to +200°C.
 
Features:
KATON® FEPM-E O-Rings are highly resistant to chemical corrosion.
The KATON® VITON® ETP Series O-Rings are exceptionally unique, offering excellent resistance to steam and a wide range of aggressive chemicals and fluids, including aliphatic and aromatic hydrocarbons, acids, alkalis, various alcohols, and even low-molecular-weight ketones, esters, and aldehydes. They comply with FDA standards for food contact. Pharmaceutical and food manufacturers often use EPDM or silicone rubber, but while EPDM offers excellent steam resistance, its chemical resistance is relatively poor. In contrast, KATON® VITON® ETP Series materials offer the following key properties:

Chemical Resistance:
The KATON® VITON® ETP Series O-rings are made from peroxide-cured elastomers, with the main difference from the AFLAS® Series being that the KATON® VITON® ETP Series uses the protective monomer "E". While it provides chemical resistance slightly lower than FFKM (around 85%), it is far more cost-effective. For demanding environments where full perfluoroelastomer performance is not required, the KATON® VITON® ETP Series offers the best cost-effective solution.
The KATON® FEPM-E O-Rings are made from a chemically resistant fluorocarbon material that offers significantly improved chemical resistance compared to standard FKM FK1-type fluororubber.

Extreme Chemical Resistance:
KATON® FEPM-E O-rings provide robust chemical resistance and are considered an economical alternative to FFKM perfluoroelastomers in applications where temperatures are below 204°C.
Replacement for Other Materials: KATON® FEPM-E can serve as a substitute for other perfluoroelastomers such as Chemraz®, Kalrez®, Perlast®, Isolast®, Paroflu®, and Markez®.

Versatility:
KATON® FEPM-E is a high-quality peroxide-cured fluoroelastomer with the broadest fluid resistance among all FKM elastomers. It withstands exposure to aliphatic/aromatic hydrocarbons, polar fluids, hydraulic oils, fuels/alcohols, strong bases, organic amines, and high-pH fluids.
