PPS fiber uses and properties

source：Suzhou Kingcharm New Materials Corp.  |  Release time：2022-07-29
  PPS fiber products can be used for paint, paint high temperature flue filtration, dust bag, fast air filter bag, filter bag in chemical industry, paper industry, drying in electrical industry, needle felt, coating special cable coating, Flame-retardant substances in the aerospace industry, etc., always pps fiber is a special fiber that can be used in high-temperature corrosive environments and high-performance during production. Among them, Japan's Daiwa Textile Company developed pps fiber as an industrial filter cloth coating for wet filtration. Chemical filtration, pps fiber mixed with cf can be used as a reinforcing material for high-performance composite materials.

  And the unstretched PPS fluorocarbon paint, as well as the conforming material for aerospace, has a large amorphous shape, and is exothermic at 125 ° C. The epoxy zinc-rich primer has a glass transition temperature of 93 ° C, a melting point of 281 ° C, and a temperature of 93 ° C. The heat treatment of the drawn fiber under the hood can increase the crystallinity by 60-80%. Therefore, the drawn fiber has no obvious glass transition or crystallization exothermic phenomenon, and its melting point is 284 °C. When the floor paint is improved, the density of the fiber also increases accordingly. Compared with the coating grade and the injection molding grade pps, the performance of the pps resin for fiber is very different, the degree of linearity, molecular weight, polydispersity coefficient and melt index, alkyd Paint melt viscosity and impurities have higher requirements, the basic characteristics of fiber grade pps, pps fiber non-woven filter fabric can meet the vast majority of dry filtration operations, and maintain a high level of long-term use under high temperature and dry heat. The residual strength of pps fiber can maintain its original performance under extremely harsh conditions.

  It has outstanding chemically stable epoxy zinc-rich primer, second only to PTFE fibers. Only strong oxidants can degrade fibers at high temperatures, so pps fibers are suitable for the filtration of many strong corrosive chemical media, alkyd Blending paint, like most conventional fibers, pps fiber has excellent textile processing properties and is very easy to manufacture and process, pps can not only be spun into various specifications of multifilament, polyurethane paint can also be spun monofilament, anti-corrosion paint affects the embroidery of pps There are many factors, but the main ones are the linearity of the molecular structure and melt index pps resin, the better the spinnability.
