temperature and excellent resistant corrosion, no aging, lubrication itself. The sealed Peculiarity excellence and install it expediency. It suitable for field of petrochemical, medicine, petrifaction, grocery, electron, nuclear power, vessel, etc.

Technology specification:

working temperature
working pressure
<20 Mpa
suitable medium
every chemistry matter but FL and melt alkali metals.
         density: 0.6~0.8 g/cm3.
lining of porcelain enamel, lining of glass, lining of plastics,lining of rubber, lining of graphite, and stainless steel,tower,heatchanged, pipe and flange.

Expanded PTFE Joint Sealant also suitable for large caliber equipment which the precision is crudity on face and the shape is not regular. It suitable for strong corrosion and the fluid which is not allowed any tainted .
The excellent peculiarity: It has high encapsulate peculiarity and easy to stuff up the cave and gutter on the face, close up the side, it also can expanded when it Passed through tension. so the sealing more strong when the inside pressure more high.

You just shear any portion of tape, joint the beginning and end, it can be a Sealing loop with free size and free shape.The viscosity side can fixture itself on the equipment and only use a little dint of bolt( 50Kgf / cm2), the effect is well.
Ptfe has excellent resistant corrode peculiarity, no aging, the sealing tape with unique handicraft lasting long and being broad temperature range.
Because the tape is a white ptfe product and it not to be corroded, it won’tPollute the fluid
The fixture sealing gasket need to made by hand, also waste time and cost, while You just shear any portion of tape,joint the beginning and end, it can be a Sealing loop with free size and free shape, you can save the change. The tape can fill in the side with not regular and make the equipment with corrosion& wear away usin Repeatly!
Direction using
Work off the side and choose certain width tape, then get rid of he protect paper, press and sticky the tape onoutside border of sealing face, connect the both tops on certain bolt, distance of cross spot 2CM atleast.(attention: The both  ends must cross overlay if on flat flange, parallelism overlay on concave tank flange, the distance at least 2CM.)
