Acrylonitrile butadiene styrene (ABS) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F).[2] ABS is amorphous and therefore has no true melting point.
ABS granules stands for Acrylo Nitrile Butadyne Styrene granules. Their chemical composition render them the physical properties like hardness, rigidity and the tendency to remain tough even at low temperatures. These ABS Granules consist of particles of a rubber like toughener suspended in a continuous phase of styrene acrylo nitrile (SAN) copolymer.
