Polysulphone - Psul 30% Carbon Fibre Reinforced

Polymer Type

Thermoplastic

Advantages

Superior tensile strength, creep resistance and rigidity, low coefficient of thermal expansion and very good mould shrinkage compared with unmodified PSul.

Disadvantages

Very expensive with poor electrical insulation characteristics compared with unmodified PSul. Moulded components can be highly anisotropic.
