Excellent corrosion resistance make it the most strong corrosive medium as sealing gasket, for contaminated materials are not allowed to medicine, food and other industries is particularly appropriate is the highest temperature plastics. But PTFE compression easily after cold, heat easily after creep, impact on seal performance. Joined parts usually glass fibers, graphite, platinum disulfide, to improve core for creep and thermal conductivity.
PTFE gasket is usually made by the board cut. It also works with asbestos rubber sheet, asbestos bag made of PTFE
Mat.
(1) Y-shaped cross section of the package pad, which is turning into a tube material thickness of 0.8 1mm annular sheet. Thickness from the outside
The center of the incision, the incision to release the core material. Incision open to the distance of about 1.5 an inner hole 2mm.
(2) is U-shaped broken bread pad inner diameter consistent with the flange, the flange to prevent the fluid vortex. After the release of the core material than the Y-shaped small aerial, so the internal air expansion volume is small, good sealing performance.
(3) 0.4 is a 0.8mm thick PTFE film strip, the two end surfaces which are heated and covered outside of the annular core member is U-shaped, easy to manufacture, suitable for larger diameter devices.
