Three-proof fabric is coated with PVC, PTFE, flame-retardant silicone, and other fire-resistant materials on the surface of fire-resistant fibers, providing fire, water, and mold prevention. Fire-resistant fibers offer fire resistance, while PVC, PTFE, and silicone provide water resistance. The polyvinyl chloride (PVC) coated fabric is made with glass fiber cloth, glass wool cloth, and chemical fiber cloth as the base fabric, coated with a special process. Key features include water resistance, flame retardancy, mold prevention, cold resistance, corrosion resistance (abbreviated as three-proof and five-proof fabric), resistance to aging, UV protection, easy cleaning, high heat resistance (over 180 degrees), and good thermal insulation properties.
