ABS plastic is a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S). The relative content of the three monomers can be arbitrarily changed to make various resins. ABS has the common properties of the three components. A makes it resistant to chemical corrosion and heat, and has a certain surface hardness. B makes it highly elastic and tough. S makes it possess the processing characteristics of thermoplastics and improves electrical properties. .
Plastic ABS resin is the polymer with the largest output and the most widely used polymer. It combines the various properties of PB, PAN, and PS organically, and has excellent mechanical properties of toughness, rigidity, and rigid phase balance. ABS is a terpolymer of acrylonitrile, butadiene, and styrene. A represents acrylonitrile, B represents butadiene, and S represents styrene. After actual use, it was found that ABS plastic pipes are not resistant to sulfuric acid corrosion, and will be comminuted and cracked in the presence of sulfuric acid.
Due to its three compositions, it has good properties; acrylonitrile gives ABS resin chemical stability, oil resistance, certain stiffness and hardness; butadiene improves its toughness, impact resistance and cold resistance; Styrene has good dielectric properties and exhibits good processability.
Most ABS are non-toxic, water-tight, but slightly permeable to water vapor, low water absorption rate, and the water absorption rate at room temperature for one year does not exceed 1% without changing physical properties. The surface of ABS resin products can be polished to obtain highly glossy products. It is 3-5 times stronger than ordinary plastics.
ABS has excellent comprehensive physical and mechanical properties and good low temperature impact resistance. Dimensional stability. Electrical properties, abrasion resistance, chemical resistance, dyeability, finished product processing and mechanical processing are better. ABS resin is resistant to water, inorganic salts, alkalis and acids. It is insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons. ABS resin has low thermal deformation temperature and is flammable, and has poor heat resistance. The melting temperature is 217 ~ 237 ° C, and the thermal decomposition temperature is above 250 ° C. Many of the modified ABS materials on the market today are doped with nozzles and recycled materials. As a result, the performance of customers’ molded products is not very stable.
The biggest application areas of ABS are automotive, electronics and building materials. Applications in the automotive field include automotive dashboards, body panels, interior trim panels, steering wheels, sound insulation panels, door locks, bumpers, ventilation ducts and many other components. In terms of electrical appliances, it is widely used in electronic appliances such as refrigerators, televisions, washing machines, air conditioners, computers, and copiers. In terms of building materials, ABS pipes, ABS sanitary ware, and ABS decorative boards are widely used in the building materials industry. In addition, ABS is also widely used in the packaging, furniture, sports and entertainment products, machinery and instrumentation industries.
ABS is widely used in the automotive industry.In the electrical and instrumentation industry and the machinery industry, often used as gears, auto parts, fenders, armrests, refrigerator linings, blades, bearings, handles, pipes, joints, instrument shells, instrument panels, basin safety Hats, etc .: Broader application prospects in household appliances and home electronics, such as televisions, radios, refrigerators, freezers, washing machines, air conditioners, vacuum cleaners and various small household appliances: daily necessities include shoes, bags, various travel suitcases Office equipment, toys, various containers, etc., low foam ABS can replace wood, suitable for building materials, furniture and household goods.
