Three-proof fabric is coated with PVC, PTFE, flame-retardant silicone, and other fire-resistant materials on the surface of fire-resistant fibers, thereby providing fireproof, waterproof, and anti-mold properties. 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 using special technology. Main performance features include waterproofing, flame retardancy, anti-mold, cold resistance, corrosion resistance (shortened to three-proof fabric, five-proof fabric); aging resistance; UV protection; easy to clean; high temperature resistance (over 180 degrees), and good thermal insulation properties.
