BS plastic is a terpolymer of acrylonitrile (A)-butadiene (B)-styrene (S). It combines the properties of three components, among which acrylonitrile has high hardness and strength, heat resistance and corrosion resistance; butadiene has impact resistance and toughness; styrene has high surface gloss, easy coloring and Ease of processing. The characteristics of the above-mentioned three components make ABS plastic a kind of thermoplastic with good comprehensive performance with "high quality, toughness and high rigidity". Adjusting the ratio of the three components of ABS, its performance will also change accordingly to meet the requirements of various applications, such as high-resistance ABS, heat-resistant ABS, and high-gloss ABS. ABS plastic has good molding processability. It can be molded by injection, extrusion, thermoforming and other methods. It can be processed by sawing, drilling, filing, grinding, etc. It can be bonded with organic solvents such as chloroform, and it can also be painted and electroplated. And other surface treatments. ABS has excellent mechanical properties, excellent impact strength, and can be used at extremely low temperatures. ABS has excellent wear resistance, good dimensional stability, and oil resistance. It can be used for bearings under medium loads and speeds. The creep resistance of ABS is larger than that of PSF and PC, but smaller than that of PA and POM. The flexural strength and compressive strength of ABS are relatively poor among plastic materials, and the mechanical properties of ABS are more affected by temperature.
