Styrene Maleic Anhydride copolymer - SMAc Copolymer; 30% Glass Fibre Reinforced

Polymer Type

Thermoplastic

Advantages

Improved dimensional stability, tensile strength, flexural modulus, heat distortion temperature and notched izod impact strength compared with unmodified SMA copolymer.

Disadvantages

Lower elongation at break than unmodified SMA copolymer. The incorporation of glass can cause anisotropy in mouldings.
