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.

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.

The aerospace industry is undergoing a lightweight revolution powered by specialty engineering plastics. Imported high-performance materials like PEEK, PI, and PPS, renowned for their exceptional lightness, extreme environment resistance, high strength, and flame retardancy, are increasingly replacing traditional metals in cabin interiors, engine components, avionics, and UAV structures. Advancements such as composite reinforcement and 3D printing compatibility are further expanding their applications. Amidst market growth and sustainability demands, these plastics have become key enablers for efficient and green aerospace manufacturing, with a promising future.

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.
