TD-640黑四氟盘根，又称*王盘根，该盘根由一种含有石墨的聚四氟乙烯纤维编织而成的盘根。用于所有化学介质的泵轴密封。低磨擦系数使盘根具有稳定性的长寿命，它还具有良好的抗拉强度和较高的热传导性。盘根有优良润滑性将不会割伤轴杆，并能降低轴套的更换成本
The packing made of PTFE yarn containing graphite．It is recommended for shafts for almost alI chemicals．Stability and long service lift are achieved by low friction coefficient．It has great tear strength and high thermal conductivity．This selflubrication packing does not score the shaft and minimizes sleeve rep;acement cost
适应于密封碱、溶剂、水、蒸气泵，在离心泵、压热器、搅拌器、混合器等中的酸类，除了强酸氧化物外（如王水、发烟硝酸、发烟硝酸）等。
Designed for seal alkalis。solvents，water,steam，acids except strong oxidizing acids（aqua regia，fuming nitric acid，fuming nitric acid，fuming sulfuric acid，etc．）for centrifugal pumps，autoclaes，agitators mixers．etc．
