The carpet woven from polypropylene staple fiber has the advantages of light weight, wear resistance, low price and beautiful appearance. It is very popular among consumers. Because the limit oxygen index of polypropylene is 18.6 and the ignition temperature is 570 degrees Celsius, the polypropylene carpet is flammable. Sexuality often causes fires to occur, so there are still some limitations.

Carpets made from polypropylene staple fibers are cheaper than nylon and wool carpets. And the fire level is no longer the same level.

However, in the spinning process of polypropylene staple fiber, the addition of the flame retardant masterbatch can effectively improve the flame retardancy of the carpet, thereby improving its fire resistance.
