Plastic ABS resin is currently the most productive and most widely used polymer. It integrates various properties of PB, PAN, and PS organically, and has excellent mechanical properties of toughness, stiffness, and rigidity. ABS is a terpolymer of acrylonitrile, butadiene, and styrene, A represents acrylonitrile, B represents butadiene, and S represents styrene. The actual use found that: ABS plastic pipe, corrosion resistance to sulfuric acid, smashed cracked case of sulfuric acid.
Due to its three compositions, it gives excellent performance; acrylonitrile gives ABS resin chemical stability, oil resistance, certain stiffness and hardness; butadiene improves toughness, impact and cold resistance; Styrene gives it good dielectric properties and exhibits good processability.
Most ABS are non-toxic, impervious to water, but slightly permeable to water vapor, have a low water absorption rate, and do not absorb more than 1% water absorbency at room temperature for one year without change in physical properties. The surface of the ABS resin product can be polished to give a highly glossy product.
ABS has excellent comprehensive physical and mechanical properties, excellent 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, insoluble in most alcohols and hydrocarbon solvents, and easily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons. ABS resin has a low heat distortion temperature and is flammable and has poor weather 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 water and recycled materials. Lead to customer molding products performance is not very stable.
