Injection Molding Grade, Medium Impact ABS is a subcategory of Acrylonitrile-Butadiene-Styrene. It is specially formulated to injection molding grade, medium impact. Its elastic modulus ranges from 200 to 450 MPa. Its flexural modulus ranges from 310 to 400 MPa. Its tensile strength ranges from 5500 to 7500 MPa at break. Its flexural strength ranges from 7100 to 13000 MPa. Its compressive strength ranges from 1800 to 12500 MPa. Its Izod Impact strength ranges from 3 to 9.6 J/cm. Its elongation at break ranges from 2.2 to 60 %. Its hardness ranges from 102 to 115 Rockwell R. Its specific gravity ranges from 1.03 to 1.06. Its coefficient of thermal expansion ranges from 80 to 100 x 10-6/°C. Its melting temperature ranges from 102 to 115 °C. Its molding pressure ranges from 8 to 25 MPa.
Acrylonitrile-Butadiene-Styrene, also known as ABS, is a thermoplastic. Common trade names are Cycolac and Lustran. It is tough, hard and rigid. It has good chemical resistance, dimensional stability, and creep resistance. It is electroplatable and inexpensive. It has moderate mechanical strength but with a tendency to stress crack. Also, it will be degraded (dissolved) when exposed to acetone. ABS is commonly used in electronic housings, auto parts, consumer products, pipe fittings, waste pipes, computer housings (electroplated on the inside), and automotive interior and exterior trim. ABS is considered superior for its hardness, gloss, toughness, and electrical insulation properties. Although ABS plastics are used primarily for their mechanical properties, they also have good electrical properties that are fairly constant over a wide range of frequencies.
