Polysulfone aramid fiber PSA

paper

PSA, also known as polyphenyl sulfoxide paracarbonamide fiber, PSA for short. PSA, in addition to slightly lower strength, other properties and aramid similar, but it is significantly better than aramid on fire resistance and thermal oxygen aging resistance, heating in 300℃ hot air for 100h, strength loss is less than 5%, the limit oxygen index is more than 33; There are good dyeing, electrical insulation, chemical corrosion resistance, radiation resistance and so on. Main Applications: fire clothing, special work clothes, high temperature filtration materials, F.H grade insulating paper, for safety protection, environmental protection, chemical industry, aerospace and other fields.
