Polyethylene Terephthalate - PET Mineral Filled

Sep 4 2001

Polymer Type

Thermoplastic

Advantages

High stiffness, creep resistance, HDT, tensile strength and low warpage compared with unmodified PET. Fast crystallising - therefore shorter moulding cycles.

Disadvantages

Reduced elongation at break compared with unmodified PET.
