Fluorinated Ethylene-Propylene - FEP 20% Glass Fibre Coupled

May 9 2001

Polymer Type

Thermoplastic

Advantages

Significantly increased tensile strength, HDT and flexural modulus compared with unmodified grades of FEP. The mechanical properties of moulded components can be anisotropic.

Disadvantages

Elongation at break and notched izod impact strength are reduced compared with unmodified FEP. The mechanical properties of moulded components can be anisotropic.
