1. General performance
ABS engineering plastic appearance is opaque ivory grain, its products can be colorful, and has a high gloss. The relative density of ABS is about 1.05, and the water absorption rate is low. ABS has good binding with other materials, easy to surface printing, coating and coating treatment. ABS has an oxygen index of 18 to 20 and is a flammable polymer with a yellow flame, black smoke and a distinctive cinnamon smell.
2. Mechanical properties
ABS has excellent mechanical properties, its impact strength is excellent, can be used at very low temperature: ABS has excellent wear resistance, good dimensional stability, and oil resistance, can be used for bearing 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 belong to the worse 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 product can be increased by about 10℃ after annealing treatment. ABS at -40℃ can still show a little toughness, can be used in the temperature range of -40~100℃.
4, electrical performance
ABS has good electrical insulation and is almost immune to temperature, humidity and frequency, so it can be used in most environments.
5. Environmental performance
ABS is not affected by water, inorganic salts, alkali and a variety of acids, but soluble in ketones, aldehydes and chlorinated hydrocarbons, corrosion by acetic acid, vegetable oil and other stress cracking will occur. ABS has poor weather resistance and is easy to degrade under the action of ultraviolet light. After six months outdoors, the impact strength is reduced by half.
