China SABIC ULTEM MD133 Manufacturer, Supplier, Factory

In the rapid development of electric vehicles (EVs), battery system safety remains the "Sword of Damocles" hanging over the industry. Thermal runaway, electrical spark ignition, metal corrosion—every minor risk could escalate into a fatal hazard. While traditional flame-retardant materials partially address these issues, their high costs, processing challenges, and corrosive side effects have hindered industry progress. As a global leader in chemical and material science, BASF has revolutionized this safety battle with its Red Phosphorus Flame-Retardant Ultramid® PA6. This breakthrough not only redefines performance standards for flame-retardant materials but also emerges as the ideal choice for EV core components, combining high safety, cost efficiency, and seamless mass production.

In modern firefighting equipment, the choice of material for helmet visors is of utmost importance. Today, we will delve into two high-performance plastics—PPSU and PSU—and their outstanding performance in firefighter helmet visors and other high-end applications.

Facing rising material costs, manufacturers can significantly cut expenses by switching from traditional painted or two-shot molded automotive B/C pillar trims to high-gloss PC/ASA/PMMA—a paint-free, single-shot solution. This eliminates painting defects, reduces equipment needs, and saves 101 RMB per vehicle (20M RMB/year at scale), while improving heat resistance and design flexibility. Success depends on material-performance alignment, process optimization, and supplier collaboration. Strategic material substitution, not just cheaper alternatives, drives sustainable cost reduction.

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.

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.
