Room temperature polyester needle punched felt

Room temperature polyester needle punched felt has the advantages of high porosity, good breathability, high dust collection efficiency, and long service life unique to ordinary felt filter cloth. Due to its moderate temperature resistance, up to 150 ° C, moderate acid resistance, alkalinity, and excellent wear resistance, it has become a widely used variety in felt filter materials.
