Polypropylene - PP 20% Glass Fibre Reinforced

Sep 6 2001

Polymer Type

Thermoplastic

Advantages

Better tensile strength, flexural modulus, heat distortion temperature and dimensional stability than unmodified Polypropylene.

Disadvantages

Significantly reduced elongation at break and reduced electrical characteristics compared with unmodified polypropylene. Inclusion of glass can cause anisotropy in mouldings.
