KATON®4000 SERIES
 
Temperature Range: -5°C to +200°C
                                                                                                                                          
Features:
 FEPM-P(AFLAS®) O-Rings are highly unique, offering excellent resistance to steam and a broad range of chemicals and fluids, including aliphatic and aromatic hydrocarbons, acids, alkalis, various alcohols, and even low-molecular-weight ketones, esters, and aldehydes. It meets FDA food contact standards. Pharmaceutical and food manufacturers often use EPDM or silicone rubber, but while EPDM provides excellent steam resistance, its chemical resistance is relatively poor. In comparison, KATON® FFKM series materials offer superior properties.

Chemical Resistance:
KATON® FEPM-P(AFLAS®) series O-rings use peroxides for polymerization and differ from FFKM by utilizing a protective monomer "P". Although it offers slightly lower chemical resistance (70% of FFKM and 90% of Viton® ETP), it is significantly more cost-effective. For environments with moderate demands, KATON® FEPM-P(AFLAS®) Series provides an optimal balance of cost and performance.

MAXMOLD® KATON® FEPM-P(AFLAS®) O-Ring elastomers offer the highest levels of heat and chemical resistance, making them ideal for the most demanding chemical sealing applications.

Chemical Sealing Solutions:
These elastomers provide superior sealing for pumps, valves, mechanical seals, pipe fittings, and reactors, meeting or exceeding industry requirements.
Extreme Environment Performance: Designed for stringent chemical applications, KATON® FEPM-P(AFLAS®) O-Ring elastomer seals are molded from high-grade materials that withstand extreme temperatures and aggressive chemicals.
KATON® FEPM-P(AFLAS®) O-Rings (Tetrafluoroethylene Propylene, FEPM) are fluoropolymers produced by Asahi Glass Co., offering excellent resistance to various corrosive chemicals.
