General properties: from the appearance of ABS plastic raw materials it is mainly an opaque ivory colored pellets, non-toxic, tasteless, low water absorption properties can make its products into a variety of colors, and with 90% ABS high adhesion with other materials, easy surface printing, coating and coating processing abs plastic oxygen index is 18.2, it is a flammable polymer, its flame is yellow, and Black smoke, charred but not dripping, and gives a special cinnamon flavor when burned ABS is a very good resin product with good overall properties and has a good impact over a wide temperature range Strength and surface hardness, heat distortion temperature is much higher than PA, pvc, its stability in size is also better.
Mechanical properties: ABS has excellent mechanical properties, its impact strength is good, can be used at lower temperatures in a variety of cold scenes. Even if ABS products are subject to external forces and destroyed, it may only be tensile damage ABS will not wear better than other plastics, its dimensional stability is excellent, but also has good oil resistance, can be used for medium load and speed of the bearing. ABS creep ratio PSF and PC, but smaller than PA and POM ABS flexural strength and compressive strength are poor in plastic ABS mechanical properties are greatly affected by temperature.
Thermal properties: ABS plastic is an amorphous polymer, and no significant melting point; high melt viscosity, poor liquidity, weatherability is poor, ultraviolet light can make color; heat distortion temperature of 70-107 ℃ (85 or so) After the annealing treatment, the product can also be increased by about 10 ℃, which is sensitive to temperature and shear rate. ABS can still exhibit toughness at -40 ℃ and can be used for a long period of time in the temperature range of -40 ℃ to 85 ℃ .
Electrical properties: ABS electrical insulation and excellent performance and almost no temperature, humidity and frequency of the impact of size, can be used in most environments.
Environmental performance: ABS plastic will not be affected by water, inorganic salts, alkaline alcohols and hydrocarbon solvents and a variety of acids, but can be dissolved in ketones, aldehydes and chlorinated hydrocarbons, by the glacial acetic acid, vegetable oil and other erosion will gradually The occurrence of stress cracking phenomenon occurs.
