It is a homopolymer polypropylene with high regularity, high crystallinity, and good workability, and its products are highly heat-resistant and chemical-resistant. As the lightest of the chemical fiber products,it is mainly used in clothing fabrics, industrial and disposable sanitary products, such assportswear, transportation rope and belt, diapers, etc.
