pps needle felt 's temperature is 190 degree to 230 degree, which is the best filter media for anti -acid, anti-alkali, hydrolysis resistant, but it is not so good at anti -oxidant, and applied in waste inicinerator, electric station boiler, industrial boiler, etc.
HT's PPS filter bag for dust collecting in cement plant, iron and steel plant, power plan, chemical plant are working very well, the weight from 400g/sqm, 450g/sqm, 500 g/sqm, 550 g/sqm, the treatment we can do is water and oil repellent, PTFE membrane, ptfe coating, teflon b coating, PTFE impregnation
