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.

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.

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.

​Recently, domestic polymer materials leader VISA officially released its innovative application solutions for polyphenylene oxide (PPO)-based materials in the automotive sector. This series of products, based on high-performance blends of PPE and PS, has developed over 20 differentiated grades tailored to the needs of new energy vehicles and traditional automotive components, demonstrating breakthrough progress in lightweighting, safety, and functional integration.

BASF compounds are advanced materials used in various industries for manufacturing high-performance products. But what exactly is a BASF compound, and why is it so important in the production of plastics, automotive parts, and other components? In this blog, we’ll explore the significance of BASF compounds and how they are changing the way products are made.

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.
