Ethylenetetrafluoroethylene - ETFE 30% Carbon Fibre Filled

Polymer Type

Thermoplastic

Advantages

Significantly improved tensile strength, flexural modulus, heat distortion temperature, mould shrinkage and linear expansion compared with unmodified ETFE.

Disadvantages

Significantly reduced elongation at break and notched izod impact strength. Very expensive. Incorporation of carbon fibres can cause anistrophy in mouldings and negligible electrical resistance.
