含石墨的聚四氟乙烯盘根是一种用含有石墨粒子的聚四氟乙 烯线编织而成的盘根。建议用于几乎所有化学介质的泵轴密封。 低的摩擦系数使盘根具有稳定性和长寿命，它还具有很强的 扯裂强度和较高的热传导性。盘根的自润滑性将不会划伤轴杆，并 能降低轴套的更换成本。

它可被用来密封碱、溶剂、水、蒸汽、酸，(除了强氧化性酸，王 水，发烟硝酸、发烟硫酸等)等介质的离心泵，压热器，搅拌器，混合 器等。

Graphite - PTFE packing is a braided packing of PTFE yam containing graphite particles. Recommended for shafts for almost all chemicals.

Stability and long service are achieved by low coefficient of friction, great tear strength and high thermal conductivity. This self -lubricating packing does not score the shaft and minimizes sleeve replacement cost

It is to seal alkalis, solvents, water, steam, acids except strong oxidizing adds (aqua regia, fuming nitric acid, fuming sulfuric acid, etc.)for centrifugal pumps, autoclaves, agitators, mixers, etc.
