High-temperature composite felt is a next-generation flame retardant material designed for both industrial and civilian applications. By blending aramid, pre-oxidized, PPS, and flame retardant polyester fibers in optimized proportions, this innovative felt delivers excellent heat resistance, high strength, and improved flame retardancy at a significantly lower cost. It provides reliable protection for workers in high-risk environments while also enhancing safety in public venues, transportation, and home textiles. Its durability, lightweight structure, and chemical resistance make it a highly versatile solution widely praised across multiple industries.
