Polished and dust-removed polypropylene is the trade name of polypropylene fiber. It is a fiber made by polymerization and melt spinning of propylene as raw material. Is a rising star in synthetic fibers. The main physical and chemical properties of polypropylene:
The longitudinal shape of polypropylene is straight and smooth, the cross section is round, and it is easy to clean gray.
The biggest advantage of density polypropylene is its light texture. Its density is only 0.91g / cm, which is the lightest density among common chemical fibers. Therefore, polypropylene with the same weight can get a higher coverage area than its warp fibers, that is, its specific surface area is larger.
High-strength polypropylene has high strength, large elongation, high initial modulus, and excellent elasticity. Therefore, polypropylene has good folding resistance.
Grinding, polishing, dust removal , acid and alkali resistance, polypropylene has good chemical resistance, in addition to concentrated acid, strong caustic soda, good resistance to other acids and alkalis Below 80 ° C, the instant temperature should not exceed 100 ° C, and it is easy to age. Polypropylene used as industrial filter cloth is mainly suitable for working conditions with low temperature requirements and large temperature content.
