High Temperature FKM Rubber Cord
Product Overview
KAFLON® High Temperature FKM Rubber Cord is a versatile sealing material made from fluorocarbon (FKM) elastomer, engineered for extreme temperature and chemically aggressive environments.
It is widely used for custom O-ring fabrication, gaskets, and sealing elements in applications where traditional elastomers cannot withstand high heat, chemical attack, or prolonged service life requirements.
Key Features
- Excellent high-temperature resistance up to 200°C
- Outstanding chemical and oil resistance
- Flexible for custom O-ring fabrication
- Low compression set for long-term sealing performance
- Available in continuous coils or cut-to-length
- Suitable for static and low-speed dynamic applications
