Since 2025, multiple countries have introduced a wave of trade restrictions, with the plastics industry bearing the brunt. Thailand announced a ban on plastic waste imports, Japan fully prohibited products containing perfluorooctanoic acid (PFOA), the EU expanded its 16th round of sanctions against Russia to include primary aluminum imports, and the Philippines proposed a nickel ore export ban. These measures not only disrupt raw material supplies but also reshape the global plastics trade.

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.

As a high-performance engineering material, glass fiber composites have shown wide application value in many fields due to their light weight, high strength, corrosion resistance and other characteristics.

Basic Concept of CLTE The Coefficient of Linear Thermal Expansion (CLTE) is used to characterize the degree of expansion of a material as temperature rises and to assess its risk of cracking under thermal stress. Understanding the relative expansion/contraction properties between different materials in contact is crucial for successful applications.

The J10C achieves a transformative advancement in China’s aviation sector through five core material innovations: carbon fiber composites for weight reduction, stealth coatings for RCS suppression, ultrahightemperature ceramics for extreme environments, titanium/aluminum alloys for structural reinforcement, and advanced resinbased materials for electronic warfare. These breakthroughs propel China’s aviation industry from "follower" to "leader," laying the technical foundation for subsequent models like the J20 and J35.

Engineering plastics with exceptional heat resistance maintain robust mechanical properties in high-temperature environments, making them indispensable for demanding applications. Beyond widely known high-temperature nylons, five other categories of heat-resistant engineering plastics play critical roles across industries.
