Main characteristics of ABS plastic
Date of release:2016-07-27 Author: Click:
Plastic ABS resin is the largest and most widely used polymer at present. It combines the various properties of PB, PAN and PS organically, and has excellent mechanical properties of toughness, hardness 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 pipe is not resistant to sulfuric acid corrosion and pulverized and ruptured in case of sulfuric acid.
It has three properties, which gives it good performance; acrylonitrile imparts chemical stability, oil resistance, certain rigidity and hardness to ABS resin; butadiene has improved toughness, impact and cold resistance; Styrene gives it good dielectric properties and exhibits good processability.
Most of the ABS is non-toxic, impervious to water, but slightly permeable to water vapor, with low water absorption. The water absorption rate at room temperature is not more than 1% per year and the physical properties do not change. The surface of the ABS resin product can be polished to obtain a highly glossy product.
ABS has excellent comprehensive physical and mechanical properties and excellent low temperature impact resistance. Dimensional stability. Electrical properties, wear resistance, chemical resistance, dyeability, finished product processing and mechanical processing are better. ABS resins are resistant to water, inorganic salts, alkalis and acids, are insoluble in most alcohols and hydrocarbon solvents, and are readily soluble in aldehydes, ketones, esters and certain chlorinated hydrocarbons. ABS resin has low heat distortion temperature and is flammable, and has poor weather resistance. The melting temperature is 217 to 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. The performance of the customer's molded products is not very stable.
