According to Securities Star report, data from Tianyancha APP shows that Kingfa Sci. & Tech. (600143) has obtained a new invention patent. The patent name is "A High Wear-Resistant PBT Composite Material and Its Preparation Method and Application", with the patent application number CN202311622582.2, and the authorization date is March 25, 2025.

Patent Abstract: The invention discloses a high wear-resistant PBT composite material and its preparation method and application, relating to the technical field of engineering plastics. The high wear-resistant PBT composite material of the invention comprises, by weight parts, the following components: 40 to 50 parts of PBT resin, 25 to 30 parts of wear-resistant filler, 5 to 8 parts of wear-resistant synergist, and 1 to 4 parts of surface modifier, wherein the wear-resistant filler is potassium titanate whiskers with an average fiber length of 10 to 20 μm; the wear-resistant synergist is polytetrafluoroethylene with a particle size Dv50 of 12 to 15 μm; the surface modifier is a silicone masterbatch. By incorporating potassium titanate whiskers, polytetrafluoroethylene, and silicone masterbatch into the PBT material, the invention achieves a PBT composite material with high wear resistance, accelerates the crystallization rate, and possesses good mechanical properties.
