what is acrylonitrile butadiene styrene abs
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x Â· (C 4 H 6) y Â·(C 3 H 3 N) z) is a common thermoplastic polymer.Its glass transition temperature is approximately 105 Â°C (221 Â°F). ABS is amorphous and therefore has no true melting point.BS is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The proportions can vary from 15 to 35% acrylonitrile, 5 to 30% butadiene and 40 to 60% styrene.
