Nylon Natural-Offers light weight, wide temperature range, and high abrasion resistance. Self-extinguishing. Recommended for use in enclosed environments where possibility of fire exists. Even at temperatures beyond its operating range or on exposure to flame, nylon does not give off any toxic or irritating by-products. Nylon is six times as strong as polyethylene.
