Acrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer. Its glass appearance is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerising styrene and acrylonitrile in the presence of polybutadiene.
Styrene acrylonitrile(AS) resin is a copolymer plastic consisting of styrene and acrylonitrile. It is also known as SAN. It is widely used in place of polystyrene owing to its greater thermal resistance.
Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomerstyrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and rather brittle. Polystyrene can be naturally transparent, but can be coloured with colourants.
