feature

This PTFE sealing tape retains the excellent chemical corrosion resistance of PTFE, while also possessing excellent flexibility, compression strength, creep resistance, cold flow characteristics, and high tensile strength. This sealing tape can be easily attached to flange seals

On the cover, there is almost no waste when used. This sealing strip is an economical and practical sealing material for flange sealing parts under medium and low pressure. Operating temperature: 280 ℃ Operating pressure: 6.3MPa pH value: 0-14.

Application scope:

Sealing of various enamel lining, glass lining, plastic lining, graphite lining, and flange surfaces of stainless steel, titanium steel towers, heat exchangers, reaction vessels, etc.

Sealing of flange surfaces for various pipelines and pipe fittings.

The flange surface sealing of large-diameter equipment with poor surface processing accuracy, large uneven areas, irregular shapes, and difficulty in using sufficient bolt tightening force or should not be too large.

Sealing of highly corrosive media and fluids that cannot be contaminated in the slightest.

Expanded PTFE tape, also known as interface sealing tape or soft PTFE strip, PTFE elastic tape, has various widths and thicknesses, can be formed quickly, is simple, and does not require pre cutting. It is suitable for various types of flange seals, and is easy to install and replace. The seal has a backing adhesive, making it easy and quick to install, even in the case of slight oil stains on the surface. When installing, remove the backing adhesive, stick it to the flange, and cut it on site according to the required length, without causing material waste. If a full plane seal is required, after attaching the strip seal, use a punch or other sharp tool to punch out the bolt holes at the corresponding positions. When replacing, the gasket can usually be completely torn off from the flange without leaving any residue or bonding phenomenon.

Duoyao PTFE strip commonly used specifications: width: 3-100mm thickness: 1-10mm length: 3-30m

Common physical parameters of PTFE strips: Density: 0.75g-1.5/cm3 Tensile strength: ≤ 8.0Mpa Applicable temperature: -100~280C Applicable pressure: 14Mpa Gas, 20Mpa Liquid pH: 0~14

PTFE sealing tape has a high degree of compressibility, which makes it easy to fill the voids and grooves on the sealing surface, block interface leaks, and has the characteristic of rebounding and expanding under tension. Therefore, the higher the internal medium pressure, the greater the sealing force. This is the magical characteristic of sealing tape.

PTFE sealing tape is made of pure PTFE dispersed resin, which is compressed and stretched at high temperatures. It has a low friction coefficient, chemical corrosion resistance, and good sealing performance. It can be used at temperatures ranging from -250 ℃ to+280 ℃ and is suitable for sealing reaction vessels, gas transmission generators, and various shaped mouth tanks and barrels. Mifso-630 (model) PTFE sealing tape retains the chemical corrosion resistance of PTFE, while also possessing flexibility, compression strength, excellent creep resistance, cold flow characteristics, and tensile strength.

PTFE sealing tape can be attached to the flange sealing surface, and there is almost no waste during use. The flange sealing part under medium and low pressure is a relatively economical and practical sealing material.
