1. General performance
The appearance of ABS engineering plastics is opaque and ivory colored granular material. Its products can be colored and have high gloss. The relative density of ABS is about 1.05, and the water absorption is low. The combination of ABS and other materials is good, easy to surface printing, coating and coating treatment. The oxygen index of ABS is 18 ~ 20, which is a flammable polymer. The flame is yellow, with black smoke and special cinnamon flavor.
2. Mechanical properties
ABS has excellent mechanical properties and excellent impact strength. It can be used at very low temperature. ABS has excellent wear resistance, dimensional stability and oil resistance. It 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 that of PA and POM. The bending strength and compression strength of ABS are poor in plastics. The mechanical properties of ABS are greatly affected by temperature.
3. Thermal performance
The thermal deformation temperature of ABS is 93 ~ 118 ℃, and the annealing temperature of ABS products can be increased about 10 ℃. ABS can still show a little toughness at – 40 ℃, and can be used in the temperature range of – 40 ~ 100 ℃.
4. Electrical performance
ABS has good electrical insulation, and is almost unaffected by temperature, humidity and frequency. It can be used in most environments.
5. Environmental performance
ABS is not affected by water, inorganic salt, alkali and many kinds of acids, but it is soluble in ketones, aldehydes and chlorinated hydrocarbons. It will produce stress cracking when eroded by glacial acetic acid and vegetable oil. ABS has poor weather resistance and is easy to degrade under the action of ultraviolet light; after half a year outdoor, the impact strength is reduced by half.
