Why are polypropylene high-strength yarns so widely used?
Polypropylene high-strength yarn has been used more and more along with the development of the company. Moreover, polypropylene high-strength yarn is a thin and long polymer material used in construction engineering, and its aspect ratio is generally 100. Above, and has a certain tensile strength, elastic modulus and ultimate elongation.
And polypropylene fiber is a synthetic fiber with a large amount and a wide range of applications in concrete engineering today. This is due to the excellent physical and mechanical properties of polypropylene fibers and excellent chemical stability such as acid and alkali resistance, and the wide range of raw materials, uncomplicated manufacturing technology, and relatively low price.
In addition, engineering synthetic polypropylene fibers are commonly classified by materials such as polypropylene fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, polyamide fibers, and polyester fibers. Polypropylene fiber is a fiber made by polymerizing propylene into isotactic 97% -98% polypropylene resin and then melt-extrusion. Therefore, the application of polypropylene high-strength yarn in life has become more and more widespread.
