By understanding their properties and uses, we can appreciate the significant role they play in shaping both the microscopic and macroscopic aspects of our world.

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.

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.

In the wave of the low-altitude economy, engineering plastics have become an indispensable "unsung hero" for drones and electric vertical take-off and landing (eVTOL) aircraft, thanks to their lightweight, high strength, and corrosion resistance. From reinforced nylon used in robust fuselages and landing gears, to polycarbonate forming transparent and impact-resistant canopy covers; from the stable performance of polyetheretherketone (PEEK) in high-temperature motor components, to the exceptional strength that carbon fiber composites provide for rotors and primary structures—engineering plastics play a critical role in reducing weight, extending range, structural design, and safety protection. They quietly support the performance breakthroughs and commercial adoption of low-altitude aircraft, serving as a vital foundation for the ascent of this new economic paradigm.

SABIC LEXAN™ 731S-701S is a high-flow, high-impact injection molding grade black polycarbonate (PC) material. It is opaque, with a notched impact strength of 80–90 kJ/m² and a heat deflection temperature of 130–135°C. Its melt flow index is more than 50% higher than that of standard PC, making it ideal for rapid molding of thin-wall, long-flow-path, and complex molds. Optimized mold release design reduces drag marks and improves yield. This black material delivers a high-gloss, light-blocking surface. Some batches offer V-2 flame retardancy and UV stability. It is widely used in electronic housings, automotive interior light-blocking parts, medical light-avoidance components, and safety goggle frames. We offer a stable supply of genuine black material and full technical support from material selection to trial molding.
