China SABIC LEXAN HPH4504 Manufacturer, Supplier, Factory

​When Unitree H1 from YUSUR Technology twisted in Yangko dance on Spring Festival Gala’s grand stage, Tesla’s Optimus Gen2 deftly assembled circuit boards, and Figure 01 flawlessly crafted latte art, the global tech community witnessed an unprecedented revolution. Let’s explore the polymer material innovations behind seven humanoid robots:

The PC/ABS alloy combines the high strength and heat resistance (110°C) of PC with the easy processability of ABS, widely used in automotive (dashboards, door handles), 3C electronics (laptop casings), communications (5G base station covers), and home appliances. It features UV resistance, flame retardancy (V-0 rating), and dimensional stability. Defects like silver streaks and warping are addressed through drying (120°C ×4h), mold temperature optimization, flow promoters, and structural design. Nano-enhanced (thermal conductivity 1.2 W/m·K) and bio-based modifications (40% carbon reduction) are expanding its applications in new energy and medical fields.

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.

High-Performance PPS (Polyphenylene Sulfide) Film with Broad Application Prospects PPS (Polyphenylene Sulfide) is a high-performance specialty engineering plastic, classified as a high molecular weight crystalline polymer with a density of 1.35 g/cm³. It features a linear molecular structure formed by alternating benzene rings and sulfur atoms. The combination of rigid benzene rings and flexible thioether linkages endows PPS with outstanding properties, including excellent heat resistance, flame retardancy, chemical corrosion resistance, mechanical strength, and dimensional stability.

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.
