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.

Since 2025, multiple countries have introduced a wave of trade restrictions, with the plastics industry bearing the brunt. Thailand announced a ban on plastic waste imports, Japan fully prohibited products containing perfluorooctanoic acid (PFOA), the EU expanded its 16th round of sanctions against Russia to include primary aluminum imports, and the Philippines proposed a nickel ore export ban. These measures not only disrupt raw material supplies but also reshape the global plastics trade.

The shrinkage rate of plastic reflects the degree of dimensional reduction in a plastic part after it is removed from the mold and cooled. Factors affecting plastic shrinkage include the type of plastic, molding conditions, and mold structure. Different plastics exhibit varying shrinkage rates. Additionally, the shrinkage rate is significantly influenced by the part's shape, complexity of internal structure, and the presence of inserts.

BASF Ultramid T6000 (PA66/6T) is specifically developed for miniaturized electrical and electronic (E&E) components, bridging the performance gap between PA66 and PPA. This material combines excellent flow properties, easy processability, and long-lasting color stability. It exhibits superior mechanical and dielectric performance over PA66 under hot and humid conditions, while its low moisture absorption ensures dimensional stability.

In the wave of the low-altitude economy, engineering plastics have become an indispensable "unsung hero" for drones and electric vertical take-off and landing (eVTOL) aircraft, thanks to their lightweight, high strength, and corrosion resistance. From reinforced nylon used in robust fuselages and landing gears, to polycarbonate forming transparent and impact-resistant canopy covers; from the stable performance of polyetheretherketone (PEEK) in high-temperature motor components, to the exceptional strength that carbon fiber composites provide for rotors and primary structures—engineering plastics play a critical role in reducing weight, extending range, structural design, and safety protection. They quietly support the performance breakthroughs and commercial adoption of low-altitude aircraft, serving as a vital foundation for the ascent of this new economic paradigm.

Engineering plastic modification is like "turning stone into gold," leveraging three core technologies—additives, fillers, and flame retardants—to dramatically enhance resin performance. Additives enable toughening, compatibilization, and anti-aging with minimal dosage; fillers like glass fibers, PTFE for lubrication, or minerals balance rigidity, toughness, and cost; flame retardants provide self-extinguishing safety. As an integrated enterprise specializing in trade, application development, and molding, we deliver tailored engineering plastic solutions through precision modification formulations.
