FEP
Fluorinated Ethylene-Propylene
FEP is a transparent fluoroplastic with properties similar to PTFE but with the advantage that it can be melt processed. The material has excellent chemical resistance, very low friction and good optical clarity. FEP is resistant to virtually all chemicals except molten alkali metals and has a usage temperature range from -200 °C to +200 °C. The material is used in the chemical process industry, the semiconductor industry and as sight glasses in laboratories. FEP is available in two variants from us: FEP AB (amorphous) and FEP GB (glass reinforced).
