Ethylenetetrafluoroethylene - ETFE 30% Glass Fibre Filled

Polymer Type

Thermoplastic

Advantages

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

Disadvantages

Reduced elongation at break and impact strength compared with unmodified ETFE. Incorporation of glass can produce anisotropic mouldings.
