PTFE Packing Yarn with Graphite

In order to cope with the strict requirement on packing from the higher speed dynamic sealing,we've developed the PTFE Yarn with Graphite.This product keeps the PTFE's advantages such as corosion and high temperature resistance as well as self lubrication.ln addition, its graphite component helps more quickly disspate the heat from fricion,prevent the packingfrom overheating under high rolling speed,and protect the sealing surface from damage.Such features effectively control leakage and prevent parts from heating damage. PTFE Packing Yarn with Graphite product has two models -- Common Model and High Graphite Model.The Common Model offers great cost effectiveness.The High Graphite Model contains higher content of graphite without reducing the strength of PTFE yarn,so that the packing gains better thermal conductivity .Such feature can further reduce the abrasion when starting torque and the shaft,greatly extend the equipment running time,and reduce the cost of maintenance.

Advantages of FEP features

1. FEP can also be made into heat shrinkable tubes, which can be used for coating transfer rollers in printing presses. 2.High surface quality can prevent print adhesion, contamination and discoloration. 3. In the medical industry, FEP tubes are mainly used as catheters or in the field of endoscopy. 4. It also prevents contamination of the delivered liquid during the injection process. 5. Therefore, the biocompatibility of FEP for medical use is also excellent. 6. FEP can be sterilized by all conventional methods.

Polytetrafluoroethylene ---- performance chapter

PTFE has very high chemical resistance, for example, in concentrated sulfuric acid, nitric acid, hydrochloric acid, even boiling in aqua regia, its weight and performance are not changed, and almost insoluble in most solvents, only slightly soluble in full alkane (about 0.1g/100g) above 300 ℃. Polytetrafluoroethylene does not absorb moisture, non-combustible, extremely stable to oxygen and ultraviolet light, so it has excellent weather resistance.
