A soft product made of PTFE fine powder as a raw material and processed by a new process. White, continuous rope, rounded in cross section. It has a high degree of flexibility, excellent filling, self-lubricating, low coefficient of friction, corrosion resistance and other properties.
Loading is quick and easy. It is generally not necessary to disassemble the valve during filling. Simply wrap the rope-like packing around the valve stem, push the stuffing box, tighten the cap, and the packing is pressed into a dense whole.
Excellent sealing performance. The unique microstructure of expanded polytetrafluoroethylene gives the product excellent flexibility and moldability, making it easy to fill the internal voids of the stuffing box, even all the pits and grooves on the stem and body. This also prevents corrosion or worn old valves from being replaced or repaired.
long lasting. Because of its long-term softness and plasticity, the leak gap is filled at any time, and because it is not corroded, it will not age and can be used for a long time.
The valve is flexible and light to open and close. Because PTFE has the lowest coefficient of friction and excellent self-lubricity.
Does not contaminate the fluid in the pipeline. Because it is white and clean, it will not fall off due to corrosion and aging, making it especially suitable for medicine, fine chemicals, food and other industries.
The specifications are versatile, reducing the storage of fillers and saving money. Only a few different sizes of stem packing are available to meet the needs of most valves.https://www.yihaoptfe.com/
