As a commonly used tarpaulin, polyethylene tarpaulin is of great concern to everyone. In order to enhance its fire resistance, plastic tarpaulin manufacturers will add some flame retardant fibers to it. Fuel fibers are mainly divided into two categories:
1. Flame-retardant fiber (also known as flame-retardant fiber): The fiber will burn when ignited by a medium or small fire source. Once the fire source is removed, the fiber flame can extinguish itself quickly and will not spread. For example, chlorine fiber, acrylic fiber, vinyl chloride fiber, flame-retardant polyester fiber, flame-retardant acrylic fiber, flame-retardant nylon, flame-retardant viscose fiber, flame-retardant polypropylene, wool, etc.
Polyethylene tarpaulin has good chemical stability, and can withstand dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amines, hydrogen peroxide, sodium hydroxide, hydrogen at room temperature Potassium oxide and other solutions. Polyethylene is a typical thermoplastic, it is a flammable white powder that is odorless, tasteless and non-toxic. The molded PE resin is waxy pellets that are extruded and pelletized, and the appearance is milky white. The melting point is 100-130℃, and its low temperature resistance is excellent, and the low use temperature can reach -100~-70℃. It can still maintain good mechanical properties at -60℃, but the use temperature is 80~110℃.
