Polysulphone - Psul 30% Glass Fibre Reinforced

Sep 5 2001

Polymer Type

Thermoplastic

Advantages

Better flammability characteristics, superior tensile strength, flexural strength and notched izod impact strength, excellent creep resistance, slightly improved heat distortion temperature and good mould shrinkage compared with unmodified PSul.

Disadvantages

Elongation at break significantly reduced compared with unmodified PSul. The mechanical properties of moulded components can be anisotropic.
