General performance: From the appearance of abs plastic raw materials, it is mainly an opaque ivory grain, non-toxic, tasteless, low water absorption characteristics can make its products into a variety of colors, and has more than 90% high gloss. ABS has good combination with other materials and is easy to surface printing, coating and plating treatment. abs plastic has an oxygen index of 18.2, it is a flammable polymer, its flame is yellow and has black smoke, charred but does not drip, and gives off a distinctive cinnamon smell as it burns. ABS is a resin product with very good comprehensive performance, which has good impact strength and surface hardness in a wide temperature range, and the thermal deformation temperature is much higher than PA and pvc, and its stability is also better in terms of size.
ABS plastic
Mechanical properties: ABS has excellent mechanical properties, its impact strength is very good, can be applied to a variety of cold scenes at lower temperatures. Even if the ABS product is damaged by external force, it can only be tensile failure rather than impact damage. ABS has better wear resistance than other plastics, excellent dimensional stability, and good oil resistance, and can be used for bearings under moderate load and speed. The creep property of ABS is larger than PSF and PC, but smaller than PA and POM. The bending strength and compressive strength of ABS are poor among plastics. The mechanical properties of ABS are greatly affected by temperature.
Thermal properties: ABS plastic is an amorphous polymer, and has no obvious melting point; The melt has high viscosity, poor fluidity, poor weather resistance, and can be discolored by ultraviolet light. The thermal deformation temperature is 70-107 ℃(about 85), and the product can be increased by about 10℃ after annealing. It is sensitive to temperature and shear rate. ABS can still show a certain toughness at -40 ° C and can be used for a long time in the temperature range of -40 ° C to 85 ° C.
Electrical performance: ABS has excellent electrical insulation performance and is almost unaffected by temperature, humidity and frequency, and can be used in most environments.
Environmental performance: ABS plastic will not be affected by water, inorganic salts, alkali alcohols and hydrocarbon solvents and a variety of acids, but can be dissolved in ketones, aldehydes and chlorinated hydrocarbons, by ice acetic acid, vegetable oil and other erosion will gradually produce stress and crack phenomenon.
