With the popularity of electric vehicles around the world, the technical requirements for key components are also increasing.

Special engineering plastics, as the pinnacle of the field of polymer materials, are a class of high-end engineering plastics with characteristics such as high temperature resistance (long-term operating temperature > 150°C), high strength, and corrosion resistance. Their core value lies in achieving metal substitution through unique molecular structure design, playing an irreplaceable role in strategic industries such as aerospace, new energy, and electronic information. Currently, the global industry is undergoing a structural upgrade from general-purpose plastics to high-performance materials. Special engineering plastics, with their revolutionary advantage of "replacing steel with plastics," have become a key material for the transformation and upgrading of advanced manufacturing.

The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

Automotive engineering plastics are driving comprehensive technological upgrades and green transformations across body structures, exterior systems, powertrain-chassis, and interiors through innovations in lightweighting, high performance, and sustainability.

Xiaomi's 3nm self-developed Xuanjie O3 chip fuels demand for semiconductor-grade engineering plastics including PEEK, LCP, and PPO. As China pushes chip self-reliance, importers should secure stable sources for high-end materials to strengthen their role in the supply chain.

Alibaba invests in Qianfan Constellation, launching a mega satellite network. Demand for PEEK, PI and LCP specialty engineering plastics is set to boom, opening a high-growth window for aerospace lightweight materials.
