Acrylonitrile Butadiene Styrene - ABS High Impact High Heat

May 4 2001

Polymer Type

Thermoplastic

Advantages

Higher heat distortion temperature than conventional grades of ABS by approx. 15°C ( 25°F ) at 0.45Mpa ( 66psi ).

Disadvantages

Requires higher mould surface temperatures and higher temperature profiles in processing than typical grades of ABS. Hence moulding cycle times are likely to be longer.
