ABS is a terpolymer of acrylonitrile, butadiene and styrene, A for acrylonitrile, B for butadiene, and S for styrene.
ABS engineering plastics are opaque ivory-colored pellets, and their products can be colored and highly glossy. AbS relative density of about 1.05, low water absorption rate. ABS is well combined with other materials and is easy to finish with surface printing and coating. ABS oxygen index of 18 to 20, is a flammable polymer, the flame is yellow, there is black smoke, and emits a special cinnamon flavor.
ABS has excellent mechanics, its impact strength is very good, can be used at very low temperatures: ABS wear resistance is good, dimensional stability is good, but also has oil resistance, can be used in medium loads and speed bearings. ABS is more creep-resistant than PSF and PC, but smaller than PA and POM. AbS bending strength and compression strength are poor in plastic. The mechanics of ABS are greatly affected by temperature.
AbS thermal deformation temperature of 93 to 118 degrees C, after annealing treatment the product can also be increased by about 10 degrees C. ABS engineering plastic can still show a little toughness at -40 degrees C and can be used in the temperature range of -40 to 100 degrees C.
ABS is electrically insulated and virtually unaffected by temperature, humidity and frequency and can be used in most environments.
ABS is not affected by water, inorganic salts, alkalis and a variety of acids, but can be soluble in ketones, aldehydes and chlorocarbons, by ice acetic acid, vegetable oil and other erosion will produce stress cracking. ABS has poor weather resistance and is prone to degradation under the influence of ultraviolet light; After six months outdoors, the impact intensity dropped by half.
