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.

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.

The PC/ABS alloy combines the high strength and heat resistance (110°C) of PC with the easy processability of ABS, widely used in automotive (dashboards, door handles), 3C electronics (laptop casings), communications (5G base station covers), and home appliances. It features UV resistance, flame retardancy (V-0 rating), and dimensional stability. Defects like silver streaks and warping are addressed through drying (120°C ×4h), mold temperature optimization, flow promoters, and structural design. Nano-enhanced (thermal conductivity 1.2 W/m·K) and bio-based modifications (40% carbon reduction) are expanding its applications in new energy and medical fields.

In modern industry and everyday life, friction and wear of mechanical components consume energy, shorten equipment life, and can also cause annoying noise. How can you achieve smoother gears, more durable bearings, and quieter equipment? The application of self-lubricating plastic materials provides an innovative solution to this dilemma. This material not only retains the advantages of traditional plastics, such as light weight and easy molding, but also "self-lubrication", becoming an effective means for mechanical engineers to solve friction and wear problems.

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 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.
