With the increasing demand for high-frequency and high-speed transmission, PEI has reduced its dielectric constant to below 3.0 (at 1 GHz) through molecular structure optimization (such as the introduction of fluorinated groups), making it a core material for 5G millimeter-wave connectors.

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.

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.

Plastic DURACON POM (polyoxide), due to its outstanding mechanical properties and processing performance, has become an important material for many high-precision and wear-resistant parts, and its application fields are very wide.

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.

BASF Ultradur PBT, with its unique polymerization process, achieves a precise balance between hardness and toughness in the molecular structure design.
