Polyamideimide - PAI Glass Fibre Reinforced

Sep 16 2001

Polymer Type

Thermoplastic

Advantages

Significantly improved flexural modulus, improved mould shrinkage, tensile strength and oxygen index compared with unmodified PAI.

Disadvantages

Reduced elongation at break and notched izod impact strength. Incorporation of fibres can produce anisotropic mouldings.
