With the popularity of electric vehicles around the world, the technical requirements for key components are also increasing.

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.

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.

NORYL is a NORYL resin owned by SABIC. NORYL was previously a trademark of GE and is the symbol of polyphenylene ether (PPO) resins in the group. It is one of the world's five major general engineering plastics. They combine the high heat resistance of polyphenylene ether resins at a low cost, good electrical properties, excellent hydrolytic stability, and the ability to be packaged with halogen-free flame retardants, with excellent dimensional stability, good processability, and low specific gravity. NORYL resins have good mechanical and chemical properties and may be suitable for a wide variety of 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.
