Three-proof fabric is coated with PVC, PTFE, flame-retardant silicone, and other fire-resistant materials on the surface of fire-resistant fibers, making it fireproof, waterproof, and moldproof. Fire-resistant fibers offer fire resistance, while PVC, PTFE, and silicone provide waterproofing. Polyvinyl Chloride (PVC) coated fabric is made with glass fiber fabric, glass wool fabric, and chemical fiber fabric as the base fabric, coated with a special process. Main performance characteristics: waterproof, flame-retardant, moldproof, cold-resistant, and corrosion-resistant (commonly known as three-proof fabric, five-proof fabric); aging resistance; UV protection; easy to clean; high temperature resistance (over 180 degrees), and good thermal insulation properties.
