ABS sheets is the most widely used engineering thermoplastic today. ABS is formed by the polymerisation of styrene and acrylonitrile on to thermoplastic rubber which is then melt compounded with styrene acrylonitrile. The combinations of the copolymers gives ABS excellent surface appearance, stronger, stiffer and tougher than high impact polystyrene and is also superior to it in its resistance to high temperatures and chemicals. It has good impact strength, formability, stiffness, excellent aesthetic qualities, and toughness, plus general purpose, low cost material. Applications include aircraft interior trim, cassette holders, tote bins and trays, automotive parts, luggage, and more.
