Material Properties of Automotive Plastic Injection Molding
ABS has excellent comprehensive physical and mechanical properties and excellent low-temperature impact resistance. Dimensional stability. Electrical properties, wear resistance, chemical resistance, dyeing, finished product processing, and mechanical processing are better. ABS resin is resistant to water, inorganic salts, alkali, and acid, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehydes, ketones, esters, and some chlorinated hydrocarbons. ABS resin thermal deformation temperature is low flammable, poor weather resistance. The melting temperature ranges from 217 ℃ to 237℃, and the thermal decomposition temperature is above 250℃. Today’s modified ABS materials on the market, many are doped with spout materials, and recycled materials. As a result, the customer molding product performance is not very stable.

Mechanical properties of
Plastic ABS has excellent mechanical properties, its impact strength is excellent, can be used at very low temperature; Plastic ABS has excellent wear resistance, good dimensional stability, and oil resistance, which can be used for bearings under medium load and low speed. The creep resistance of ABS is greater than that of PSF and PC, but smaller than that of PA and POM.
3
The thermal performance
The thermal deformation temperature of ABS plastic is 93~118℃, which can be increased by about 10℃ after annealing. ABS can still show a certain toughness at -40℃ and can be used in the temperature range of -40~100℃.
4
Electrical performance
Plastic ABS has good electrical insulation and is almost unaffected by temperature, humidity and frequency. It can be used in most environments.

PC/ABS recycled material is an important engineering plastic alloy, widely used in automotive, electronic and electrical, office and communication equipment and other fields. Nowadays, in order to meet the special requirements of fire safety in the application field (especially electronic and electrical products), the flame retardant technology of PC/ABS alloy has become a research hotspot. However, with the progress of science and technology, the demand for environmental friendliness of materials is becoming higher and higher, and the harm brought by traditional halogen flame retardancy is becoming more and more obvious.
