Properties And Characteristics Of PP Chemical Fibers
Jul 11, 2018

It is one of the most moisture-resistant synthetic fibers. The moisture regain is close to zero under the standard conditions. When it is wet, it absorbs only 0.6% moisture by weight and does not change its properties. Polypropylene needle felt has good wear resistance and high elastic recovery, and the creep elongation of polypropylene fiber is larger than that of polyester fiber when the load increases. Polypropylene dust filter bags can withstand 90 C temperature, the chemical properties of polypropylene is the best of all chemical fibers, it is acid-resistant and alkali-resistant. In addition to chlorofluorocarbon acid, concentrated nitrate acid and other oxidizing acids, the resistance to other acids is very good. Alkali resistance is also strong, in addition to concentrated caustic sodium, the other bases have no effect on it, but also resistant to general organic solvents. It has good electrical insulation, but polypropylene fiber is easy to be affected by light and heat decomposition. Polypropylene is a kind of excellent thermoplastic fiber. Polypropylene felt is often used in low temperature pulse filter bag in smelting plant, chemical industry and medicine factory. Polypropylene is specially used in wet places. It is limited by only low temperature resistance.
