New trends in engineering plastics to replace metals

The surface after injection molding is very smooth and beautiful, and can also be used on structural appearance parts. Another example is Solvay's AmodelPPA. Some models have a heat distortion temperature of up to 310 ° C and are resistant to hydrolysis and can be used in high temperature and humid environments. In fiber-reinforced plastics, long-fiber thermoplastics have also risen sharply at home and abroad in recent years. The fibers after molding can still maintain a considerable length and are intertwined, so that the finished product has both high rigidity and good toughness; Long-fiber materials have been widely used in automotive, aerospace, medical, transportation, sporting goods, household appliances and electronic products due to their stability, light weight and corrosion resistance. In the current car design, plastic parts account for 16% of the weight of the car. The first cornerstone (Hong Kong) Co., Ltd. estimates that this percentage will continue to increase to about 25% within five years. This trend makes the new generation of cars more fuel efficient, less carbon emissions and more comfortable.

Compared with general-purpose plastics, engineering plastics can achieve higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in electrical and electronic, automotive, construction, office equipment, machinery, aerospace and other industries. It has become an international trend to replace steel and plastic. Engineering plastics has become the fastest growing field in the plastics industry in the world. Its development not only supports the national pillar industries and modern high-tech industries, but also promotes the transformation of traditional industries and product structure. According to analysis, with the continuous development of the domestic economy, the demand for engineering plastics will further increase, and the development prospects of China's engineering plastics industry are very broad.
