Description

FEP copolymer possesses excellent chemical stability and outstanding radiation resistance, as well as non-flammability, good electrical and mechanical properties.

• Long-term no-load operating temperature: -80 to 170 °C

• Maximum short-term operating temperature: up to 200 °C

• Radiation resistance: total dose up to 5 × 10⁴ Gy

Thermal stability is slightly lower than PTFE but can be used long-term at -85 to 205 °C.
