产品说明 Product description
PTFE 针刺毡是采用 PTFE(聚四氟乙烯纤维)经三维针刺而成的一种过滤材料。PTFE 纤维为大分子线性结构,因而具有极强的耐 温、耐磨、耐化学稳定性,广泛适用于钢铁、电力、垃圾焚烧等各种恶劣的烟气过滤环境。
PTFE needle felt is a kind filter material which is made of PTFE (PTFE fiber) through three dimensional needling.PTFE fiber is a macromolecular linear structure,so it has a strong temperature resistance,wear resistance,corrosion resistance,chemical stability,widely used in iron and steel,electricity,garbage incineration and other harsh flue gas filter environment.
