By understanding their properties and uses, we can appreciate the significant role they play in shaping both the microscopic and macroscopic aspects of our world.

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.

First plastic gas tank for commercial vehicles made of BASF's high-performance Ultramid® polyamide, which weighs up to 20 percent less than an aluminum alternative

Here is the English translation of the provided text, maintaining the structure, terminology, and nuances: From the Industrial Revolution to the Rise of the Polymer Industry Since DuPont invented nylon and coined the term "NYLON," launched the ZYTEL brand in 1954, and up to the present day, the modified applications of nylon and high-temperature nylon (HTN) in sectors like automotive, electronics, consumer goods, military, and aerospace have spanned over 70 years. However, the foundational equipment for modifying engineering plastics is certainly not something a 300,000 RMB extruder can handle.

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.

Ultramid® A221 is a high-performance unfilled PA66 grade from BASF, specially designed for injection molding. Featuring a special nucleating agent, it enables fast-cycle molding that significantly boosts production efficiency. The material offers high strength, good stiffness, excellent thermal stability with a melting point of approximately 260°C, outstanding dimensional stability, and strong chemical resistance. It is widely used in automotive manufacturing, electrical and electronics, and industrial machinery sectors.
