Acrylonitrile butadiene styrene (ABS) is a thermoplastic polymer. The most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to further improve impact resistance, toughness, and heat resistance. ABS has useful characteristics within a temperature range from −20 to 80°C, it has a glass transition temperature of approximately 105°C. ABS is amorphous, meaning it has no true melting point. ABS’s light weight and ability to be injection molded and extruded make it useful in manufacturing products such as musical instruments, golf club heads, luggage and protective carrying cases, small kitchen appliances, and toys.
