Polyethylene Terephthalate - PET 45% Glass Fibre Reinforced

Polymer Type

Thermoplastic

Advantages

Very high flexural modulus, tensile strength, notched izod impact strength, maximum operating temperature, heat distortion temperature and low mould shrinkage compared with unmodified PET.

Disadvantages

Significantly reduced elongation at break compared with unmodified PET. Incorporation of glass fibres can cause anisotropy in mouldings.
