What are the properties of ABS board materials?
1, general performance
ABS engineering plastics are opaque and ivory-colored pellets, and their products can be colorful and have high gloss. The relative density of ABS is about 1.05, and the water absorption rate is low. ABS combines well with other materials and is easy to surface print, coat and coat. ABS has an oxygen index of 18 to 20 and is a flammable polymer. The flame is yellow with black smoke and a special cinnamon flavor.
2, mechanical properties
ABS has excellent mechanical properties and excellent impact strength. It can be used at extremely low temperatures: ABS has excellent wear resistance, good dimensional stability and oil resistance, and can be used for bearings under medium load and speed. The creep resistance of ABS is larger than that of PSF and PC, but smaller than PA and POM. The bending strength and compressive strength of ABS are poor in plastics. The mechanical properties of ABS are greatly affected by temperature.
3, thermal performance
The heat distortion temperature of ABS is 93~118 °C, and the product can be improved by about 10 °C after annealing. ABS can still exhibit a little toughness at -40 ° C and can be used in the temperature range of -40 to 100 ° C.
4, electrical performance
ABS has good electrical insulation and is hardly affected by temperature, humidity and frequency, and can be used in most environments.
5, environmental performance
ABS is not affected by water, inorganic salts, alkalis and various acids, but is soluble in ketones, aldehydes and chlorinated hydrocarbons. It is subject to stress cracking due to erosion by glacial acetic acid and vegetable oil. ABS has poor weather resistance and is prone to degradation under the action of ultraviolet light; after half an year outdoors, the impact strength is reduced by half.
