ABS is one of the most widely used and versatile thermoplastics with color of opaque ivory. It is made up of three monomers: acrylonitrile, butadiene, and styrene. The proportions of the monomers typically range from 25% to 40% acrylonitrile, 10%–30% butadiene, and 30%–60% styrene. This material has excellent toughness and rigidity, low creep, high dimensional stability, low weight and a good resistance to acids, alkalis, and abrasion.
- High Rigidity & Impact Resistance：It remains hard, rigid, and tough even at low temperatures.
- High Applicability due to its low melting point.
- Good Bonding Performance with other materials. e.g., surface printing, coating treatment.
- Good Insulating Properties
