Plastic ABS resin is the largest and most widely used polymer, which organically unifies the various properties of PB, PAN and PS, and has excellent mechanical properties with balanced toughness, hardness and rigidity. After actual use, it was found that ABS plastic pipes are not resistant to sulfuric acid corrosion, and will be crushed and cracked when exposed to sulfuric acid.
Most ABS is non-toxic, impermeable, but slightly permeable to water vapor, low water absorption, room temperature immersion for one year water absorption rate does not exceed 1%, and the physical properties do not change. The surface of ABS resin products can be polished to produce highly glossy products. In addition, ABS is 3-5 times stronger than general plastics. ABS plastic is odorless and has an ivory-colored translucent appearance, or transparent granules or powders. The density is 1.05~1.18g/cm3, the shrinkage is 0.4%~0.9%, the elastic modulus value is 2Gpa, the Poisson's ratio is 0.394, the hygroscopicity is <1%, the melting temperature is 217~237 °C, and the thermal decomposition temperature is >250℃.
ABS has excellent comprehensive physical and mechanical properties, good low temperature impact resistance, dimensional stability, electrical properties, wear resistance, chemical resistance, dyeing, finished product processing and mechanical processing. 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 some chlorinated hydrocarbons. ABS resin has low heat deflection temperature, flammability, and poor heat resistance. Its 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 nozzle materials and recycled materials. As a result, the performance of the customer's molded products is not very stable.
