F-501expanded PTFE Joint sealant

I. Definition:
It is a soft new-type packing material with PTFE powder as the raw material, and processed with layering, high temperature tension and other new technologies.

II. Property:
It has low friction coefficient, good fill capability, self-lubricating, corrosion resistance, etc.

1. Convenient for loading. It requires no valve off when loading, just to coil the ropy stuffing onto the valve stem, then push into the packing box and tightly lock the box cap, the stuffing is pressed into a thick and firm body.

2. Perfect sealing capability. The unique microstructure of expanded PTFE gives this product very good flexibility and mold plasticity. And the inner gaps of the packing box; even all the pits and furrows of the valve stem and body can be perfectly loaded. Thus enables those corroded, worn out old valves to work continuously without reparation or change.

3. Long service life. The stuffing are staying in a state of softness and plasticity at long time, thus makes the leaking points filled at any moment, no corrosion, no aging, and durable in use

4. Easy on-off of cold door. Expanded PTFE has the lowest friction coefficient and perfect self-lubricating capability.

5. Pollution-free seal. Expanded PTFE is a kind of pure white, clean material with stable chemical property, and its anti corrosion nature also prevents drop. So it is especially applicable in pharmaceutical, food and fine chemistry industry.

6. Good commonability of specification. Reducing stuffing inventory and lowering down the cost can be achieved by only preparing several types of stuffing in common specification. It is applicable for most types of valves. Usually it is preferred to choose the largest size stuffing, but smaller size stuffing can also be used for big size valves. And the densely sealed stuffing body can be available after tightly pressing and molding
