The polytetrafluoroethylene gasket impregnated product is a high temperature resistant product which is woven from glass fiber yarn into various thicknesses of base fabric, and then impregnated with polytetrafluoroethylene for high temperature silica gel treatment. Uses: textile printing and dyeing, printing and drying guide tape, screen printing, ultraviolet drying, food baking machine guide tape, composite plastic bag heat sealing, anti-corrosion pipe lining, etc. Dongguan Teflon axial seal ring manufacturer is a kind of engineering plastic with excellent performance. It is resistant to chemical corrosion, high and low temperature resistance, electrical insulation and surface non-stickiness. It is used by many other engineering plastics. Not so much, so there is the "plastic king".

The relative separation between the sealing faces caused by the pressure and the large residual compressive stress of the PTFE pad surface are retained, thereby reducing the leak rate. The thickness of the gasket is different, and the conditions for establishing the initial seal are also different. Due to the influence of the friction force on the end face, the surface of the gasket is in a three-way stressed state, and the deformation resistance of the material is large; and the middle portion of the gasket is affected by the end portion. Smaller, its deformation resistance is also small.

The effect of the size of the PTFE pad on the product seal, under the same compression load and the same medium pressure, the leakage rate decreases with the increase of the thickness of the PTFE pad. This is because under the same axial load, the thick PTFE pad has a large amount of compression rebound. Under the condition that the initial sealing condition has been reached, the thick gasket with larger elastic reserve is better than the thin gasket. Compensation due to the medium. Teflon gaskets are easy to creep when loaded, and are typical cold flow plastics. Creep of PTFE varies with compressive stress, temperature, and crystallinity. The higher the temperature, the greater the creep.
