Engineering plastics are better than ordinary plastics in thermal stability, mechanical properties and chemical resistance, and are widely used in automotive, electronic and electrical, aerospace and other fields. Ordinary plastics dominate the field of daily necessities and packaging materials because of their low cost. Both have their own advantages and work together to promote industrial development.

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.

Injection molding often encounters burn marks, a critical defect that severely impacts product appearance and quality. This article deeply analyzes the root causes of burn marks and proposes systematic countermeasures.

Polyphenylsulfone (PPSU), hailed as "transparent gold," is a high-performance specialty engineering plastic. It combines exceptional high-temperature resistance, impact toughness, and medical-grade safety. Widely used in medical devices, infant products, aerospace, and new energy vehicles, PPSU serves as a critical material in high-end manufacturing, enabling innovative solutions across industries that demand reliability, durability, and transparency.

SABIC DU242 PEI: The Perfect Balance of High Flow and Low-Temperature Toughness SABIC ULTEM™ DU242 is a polyetherimide (PEI) blend engineered for complex parts and demanding environments. Its key strengths lie in the unique combination of high flowability (for easy processing of thin-wall, intricate geometries) and enhanced low-temperature impact resistance, while maintaining a Heat Deflection Temperature of 160°C and UL94 V-0 flame rating. As a comprehensive enterprise integrating science, industry, and trade, we not only supply this high-performance material but also leverage our technical team to provide full-chain support—from product design and material selection to molding process optimization—empowering your innovations in automotive, electronics, industrial, and other sectors.

In the engineering plastics industry, color difference control has moved far beyond visual judgment. The L, a, b values form the internationally recognized three-dimensional coordinate system for color, representing lightness, red-green hue, and yellow-blue hue respectively. Understanding these three numbers is the key to correctly interpreting colorimeter reports and pinpointing the root cause of color deviation—whether it comes from material batch variation, drying process instability, or injection molding parameter drift.
