High-strength polypropylene industrial yarn, also known as high-strength polypropylene filament, is widely used for high-strength polypropylene industrial yarns because of its light weight, super high strength, wear resistance, low thermal conductivity, acid and alkali resistance, chemical resistance, low electrostatic accumulation, and low moisture regain. Used for weaving various types of industrial spinning products. With the continuous progress of our country's industrial technology, it is expected that the demand for high-strength polypropylene industrial yarns will increase at a rate of 5% per year, especially in the industrial sector.
