Polyester needle felt normal continuous operating temperature can reach 130 ℃, 130 ℃ if temperatures in excess of long-running, its strength will lose a lot, and have a great contract, so that the size of bag changes, thereby affecting filter effects. Our company adopts special technology in the production of temperature needle felt is made of glass fiber woven fabric, matched with high quality polyester (PET), PPS, Acrylic staple fiber for surface layer, it has a high breaking strength , breaking elongation is small, heat shrinkage is small, moderate temperature, etc., to meet the working temperature requirements at 150-170 ℃, ambient temperature and high temperature filter material can not meet the filter is too wasteful necessary, to a large extent reduce operating costs. Working conditions in accordance with different requirements, our company can do all kinds of needle felt on the functional temperature processing, such as water repellent and oil, PTFE impregnated, coated, coated, etc..
