what ptfe tape
Polytetrafluoroethylene tape (Mifso-629) is made of pure polytetrafluoroethylene disperse resin by pressing strip and stretching at high temperature. It has low friction coefficient, chemical corrosion resistance and good sealing performance. It can be used for the sealing of reaction kettle, steam transmission generator and various special-shaped nozzle tanks and barrels at - 250 (-+280 (?) This tetrafluoroethylene seal retains the excellent chemical corrosion resistance of PTFE, and has excellent flexibility, compression strength, creep resistance, cold flow characteristics, and high tensile strength.
