Problems solved by technology

[0002] ABS resin is a thermoplastic engineering plastic with a wide range of uses. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size and good surface gloss. , easy to paint and color, and can also carry out secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. The general heat-resistant temperature of ABS resin is 80-90°C. In some occasions, the heat-resistant temperature of the parts made of it will not meet the requirements. This requires us to make improvements on the premise of maintaining the basic performance of ABS. Its heat resistance performance, the current heat-resistant ABS on the market, while increasing the heat-resistant temperature of general-purpose ABS, its impact toughness also drops more obviously
