White in colour. The most important mechanical properties of ABS aredensity 1057 kg / m3. impact resistance and hardness. To improve impact resistance, hardness and heat resistance several modifications can be made to the polymer.
Impact resistance can be increased by increasing the amount of polybutadiene compared to styrene and acrylonitrile, although this causes deterioration/change of other characteristics. Impact resistance does not decrease rapidly at low temperatures.Dimensional stability is excellent under low loads Therefore, by changing the proportions of its components, ABS can be produced to obtain different qualities. and two main ABS processing technologies ABS are extrusion and injection molding.
Generally the operating temperatures of ABS are between -20° and 80°C (-4 to 176°F). ABS is resistant to solvents, alkalis, concentrated hydrochloric and phosphoric acids, alcohol and animal, vegetable and mineral oils. They are soluble in esters, ketones, 1,2-dichloroethane and acetone.
