ABS shrinkage rate? 0.4%-0.6%,

The structure of ABS resin includes graft polymer with elastomer as the main chain and hard ABS resin. A graft polymer of the main chain; or a mixture of rubber elastomer and hard ABS resin.

Most ABS is non-toxic and impermeable to water, but slightly permeable to water vapor and has a low water absorption rate. The water absorption rate does not exceed 1% after being immersed in water at room temperature for one year, and the physical properties do not change. The surface of ABS resin products can be polished to obtain highly glossy products. It is 3-5 times stronger than ordinary plastic.

Extended information:

Plastic ABS has excellent mechanical properties, good impact strength, and can be used at extremely low temperatures; plastic ABS has excellent wear resistance and dimensional stability It has good performance and oil resistance, and 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.

The heat distortion temperature of plastic ABS is 93~118℃, and the temperature of the product can be increased by about 10℃ after annealing. ABS can still show a certain degree of toughness at -40°C and can be used in the temperature range of -40~100°C.
