Publication Time:

2021-11-12

Expanded PTFE sealing tape is a novel and unique sealing material made by a unique processing technology. It is a continuous strip of white pure PTFE product, with good flexibility, compression resilience, creep resistance, high and low temperature resistance, and excellent corrosion resistance, non-aging, and self-lubrication. It has excellent sealing performance and is extremely easy to install and use, making it an ideal sealing material for the chemical, pharmaceutical, petrochemical, food and beverage, electronics, power, metallurgy, and shipbuilding industries.

Applicable Media

All chemical substances except elemental fluorine and molten alkali metals.

Technical Parameters:

•Operating Temperature: -168℃~+280℃

•PH Value: 0~14

•Operating Pressure: <5 MPa (liquid) <2MPa (gas)

•Density: 0.7 (±0.05) g/cm3

Applications of Sealing Tape:

•Sealing of flanges on various enamel-lined, glass-lined, plastic-lined, rubber-lined, graphite-lined, stainless steel, and titanium steel towers, heat exchangers, and reactors.

•Sealing of flanges on various pipes and pipe fittings.

•Sealing of flanges on large-diameter equipment with poor surface processing accuracy, large uneven areas, irregular shapes, and where bolt tightening force is difficult to apply sufficiently or should not be excessive.

•Sealing of strongly corrosive media and fluids that cannot be contaminated in any way.
