PTFE needled felt bag

Product introduction

PTFE needled felt bag is a filter material made of PTFE (polytetrafluoroethylene fiber) by three-dimensional needled. PTFE fiber linear structure of large molecules, so it has strong temperature resistance, wear resistance, corrosion resistance, chemical resistance stability, widely used in steel, electric power, waste incineration and other bad flue gas filtration environment.
