聚四氟乙烯在240 °C的连续运行、瞬间260 °C的温度条件下，能耐全部PH值范围内的酸碱侵蚀;因此，常与其他材质混纺提高滤料耐化学性能。适用于需耐腐蚀性的恶劣条件、滤料使用寿命要求高的场合;垃圾焚烧、碳黑生产、钛白粉(TIO2) 生产及部分金属的初次冶炼、精炼及化学生产过程。

Superior product-polytetrafluoroethylene (PTFE) dust bag

Under the continuous operation of 240 °C and the instantaneous temperature of 260 °C, PTFE can withstand acid and alkali erosion in the entire pH range; therefore, it is often blended with other materials to improve the chemical resistance of the filter material. It is suitable for occasions requiring severe corrosion resistance and high service life of filter materials; garbage incineration, carbon black production, titanium dioxide (TIO2) production, and primary smelting, refining and chemical production processes of some metals.
