High-quality non-woven fabric, high temperature resistant felt fabric, good flame retardant effect

Polyacrylonitrile pre-oxidized fiber (panof) is abbreviated as pre-oxidized fiber. It is the basic material for the production of carbon fiber. It has good flexibility, corrosion resistance, high temperature resistance, and non-flame. Fabric and anti-corrosion filler.　　 Non-woven fabric made of pre-oxygenated filaments, excellent flame retardant and high temperature resistance stability, no shrinkage and no droplets during combustion, good heat insulation effect, acid and alkali corrosion resistance, and radiation protection. 1. Preparation of polyacrylonitrile-based carbon felt and graphite felt; 　　2, acid resistance, alkali resistance, resistance to various oils and organic solvents; 　　3, fire protection, fire blankets, heat-resistant flame retardant materials for special construction isolation; 　　4, temperature resistance Sealing material.
