China VICTREX PEEK 450FC30 Manufacturer, Supplier, Factory

With the increasing demand for high-frequency and high-speed transmission, PEI has reduced its dielectric constant to below 3.0 (at 1 GHz) through molecular structure optimization (such as the introduction of fluorinated groups), making it a core material for 5G millimeter-wave connectors.

Special engineering plastics, as the pinnacle of the field of polymer materials, are a class of high-end engineering plastics with characteristics such as high temperature resistance (long-term operating temperature > 150°C), high strength, and corrosion resistance. Their core value lies in achieving metal substitution through unique molecular structure design, playing an irreplaceable role in strategic industries such as aerospace, new energy, and electronic information. Currently, the global industry is undergoing a structural upgrade from general-purpose plastics to high-performance materials. Special engineering plastics, with their revolutionary advantage of "replacing steel with plastics," have become a key material for the transformation and upgrading of advanced manufacturing.

As a high-performance engineering material, glass fiber composites have shown wide application value in many fields due to their light weight, high strength, corrosion resistance and other characteristics.

High-Performance PPS (Polyphenylene Sulfide) Film with Broad Application Prospects PPS (Polyphenylene Sulfide) is a high-performance specialty engineering plastic, classified as a high molecular weight crystalline polymer with a density of 1.35 g/cm³. It features a linear molecular structure formed by alternating benzene rings and sulfur atoms. The combination of rigid benzene rings and flexible thioether linkages endows PPS with outstanding properties, including excellent heat resistance, flame retardancy, chemical corrosion resistance, mechanical strength, and dimensional stability.

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.

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.
