PFC-7 is a high-strength composite material based on modified phenolic resin, reinforced with ultra-strong specialty fibers, and added with solid lubricants. It is processed under specific temperature and pressure. Compared to other fiber-reinforced (cotton fiber, polyester fiber, polyamide fiber, etc.) phenolic products, PFC-7 exhibits superior compressive strength, tensile strength, wear resistance, flame retardancy, heat resistance, and chemical corrosion resistance. It is capable of adapting to complex working conditions in various demanding environments.
