Polyphenylene Sulphide - PPS Glass Fibre and Bead Reinforced

Sep 7 2001

Polymer Type

Thermoplastic

Advantages

Good cost/performance ratio. Better heat distortion temperature and flexural modulus than 40% glass fibre reinforced PPS.

Disadvantages

Reduced volume resistivity, dielectric strength, tensile strength, elongation at break and notched izod impact strength when compared with 40% glass fibre reinforced PPS.
