This article systematically expounds on the development process of China's special engineering plastics industry from the germination stage to the maturity stage, analyzes the current industry situation at the critical stage of transition, covering influencing factors such as policies, technologies, and the market. It also introduces the upstream, midstream, and downstream situations of the industry chain, including the supply of raw materials, production, and the demand in application fields. At the same time, it explores the opportunities and challenges of green development that the industry is facing.

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.

TPU (Thermoplastic Polyurethane Elastomer) is a versatile material that combines the elasticity of rubber with the strength of plastic. Known for its exceptional abrasion resistance, weather durability, environmental friendliness, and processability, TPU is widely used in diverse fields such as athletic footwear, electronic protection, automotive components, medical devices, and even flexible electronics. As a "perfect hybrid" of rubber and plastic, TPU continues to drive product innovation and industrial upgrading, offering reliable and sustainable material solutions for modern life and industrial development, quietly reshaping our manufacturing and consumer experiences.

Liquid Crystal Polymer (LCP) is a high-end engineering plastic renowned for its exceptional strength, heat resistance, dimensional stability, and superior electrical properties. As a critical material for 5G communications, precision medical devices, and automotive electronics, it is indispensable in core components like millimeter-wave antennas, absorbable stents, and high-voltage connectors. We are more than just a supplier of LCP resin; we are a solutions partner offering integrated support from material selection and part design to process optimization. Committed to collaborative innovation, we empower clients to push technological boundaries and transform pioneering concepts into reliable, high-performance products.

SABIC CY6414-701 is a halogen-free flame-retardant PC/ABS alloy from the CYCOLOY™ series. It offers high heat resistance (HDT 118°C at 1.8MPa, Vicat 135°C), high flowability (MFR 14g/10min at 260°C/5.0kg), and excellent impact strength (notched Izod 800J/m). The non halogen (chlorine and bromine free) flame retardant system achieves UL94 V 0 at 1.2mm and 5VB at 2.5mm, meeting strict environmental regulations. With low CTE and good dimensional stability, it is ideal for thin wall and complex parts. Typical applications include E/E enclosures, automotive interior/exterior components, and LED lighting housings. Proper pre drying (90 110°C, 2 4h) is required before processing to ensure optimal performance.

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.
