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.

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.

In September 2025, the Shanghai Visa Plastics team embarked on a four-day trip to western Sichuan. They tempered the team spirit amid the mountains and rivers of Jiuzhaigou and Huanglong, and gained innovative inspiration from the ancient Shu civilization at Sanxingdui. They supported each other during the plateau hike, practicing the corporate belief of "win-win cooperation"; facing the thousand-year-old cultural relics, the craftsmanship spirit and technological innovation resonated across time. This was not only an enhancement of team cohesion but also an in-depth awakening of professional craftsmanship. The Visa people will carry this harvest and work together to open a new chapter in plastic technology with greater enthusiasm and more solid collaboration.

From Feb 9-10, our team escaped to Chongming Island for a spring retreat. Day 1 featured our year-end review meeting, followed by team games and a warm dinner. Day 2 brought creative crafting sessions and collaborative challenges. Though brief, these two days refreshed us amidst nature and strengthened our bonds. We return energized and united—ready to embrace the exciting journey of 2026 together!

This article delves into the complete transformation process of engineering plastic pellets from raw material to precision parts. It systematically introduces the three fundamental processes of injection molding, extrusion, and blow molding, extending to specialized techniques like thermoforming and rotational molding.
