Most ABS are nontoxic and impermeable, but slightly permeable to vapor, with low water absorption. The water absorption rate of ABS is less than 1% in one year after immersion at room temperature, and the physical properties remain unchanged. The surface of ABS resin products can be polished to obtain high gloss products.
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 resin is resistant to water, inorganic salt, alkali and acid, insoluble in most alcohols and hydrocarbon solvents, but easily soluble in aldehydes, ketones, esters and some chlorinated hydrocarbons. ABS resin has low thermal deformation temperature, flammability and poor weather resistance. The melting temperature is 217 ~ 237 ℃, and the thermal decomposition temperature is above 250 ℃. In today’s market, many modified ABS materials are doped with nozzle materials and recycled materials. As a result, the performance of customer molding products is not very stable.
