High-performance special engineering materials feature excellent high-temperature resistance, chemical corrosion resistance, mechanical strength and electrical insulation properties. Their continuous service temperature ranges from 200℃ to 260℃, while certain high-performance grades can withstand temperatures exceeding 300℃ for short-term use. These materials are widely used in semiconductors, electronics and electrical engineering, new energy, aerospace and high-end industrial sectors.

PSU is a classic transparent high-temperature resistant special engineering plastic, appearing as amber transparent pellets in its natural state. It delivers outstanding performance in hydrolysis resistance, acid and alkali resistance, high temperature resistance and creep resistance, with a long-term service temperature up to 150℃, and resists cracking after repeated high-temperature sterilization. Application Fields: hemodialysis membranes, water filtration membrane modules, water purifier components, medical devices, food-grade injection molded parts, electronic insulation parts, coating base materials.

PVDF is a representative raw material of fluoroplastics. It features extraordinary resistance to acids, alkalis, strong corrosion, ultraviolet rays and weathering, along with low friction coefficient and high insulating property. It also possesses favorable processability for membrane fabrication, injection molding and extrusion.Application Fields: Water treatment ultrafiltration/microfiltration membranes, chemical anti-corrosion coatings, lithium-ion battery binders, anti-corrosion pipelines, electronic insulation parts, epoxy anti-corrosion modification materials.
