The characteristics and application of Teflon tape

xinstSep 03, 2021

PTFE Teflon adhesive tape has a smooth surface, good adhesion resistance, chemical resistance, high temperature resistance and excellent insulation properties. It is widely used in packaging, thermoplastics, laminating, sealing and heat sealing, electronic appliances and other industries. The fabric-reinforced PTFE Teflon tape has the characteristics of high strength. It can be used in industries such as the drum of the sizing machine and the thermoplastic film stripping machine. It can be used repeatedly and is easy to replace.

Main performance characteristics

1. Used between low temperature -196℃ and high temperature 300℃, with weather resistance and anti-aging.

After practical application, if placed for 200 days at a high temperature of 250°C, not only the strength will not decrease, but the weight will not decrease; if placed at a high temperature of 350°C for 120 hours, the weight will only decrease by about 0.6%; at -180 It can maintain the original softness under the condition of ultra-low temperature.

2. Non-adhesive: The surface is smooth, and it is not easy to adhere to any substance. It is easy to clean all kinds of oil stains, stains or other attachments attached to its surface; almost all adhesive substances such as paste, resin, paint, etc. can be easily removed;

3. Chemical resistance, corrosion resistance of strong acid, strong alkali, aqua regia and various organic solvents.

4. Drug resistance and non-toxicity. It can withstand almost all pharmaceutical items.

5. It has high insulation properties (small dielectric constant: 2.6, tangent below 0.0025), anti-ultraviolet, anti-static.


The main use of Teflon tape

1. Heat-sealed pressure-adhesive parts for packaging food, dairy products, and medicines

2. Used on the surface of the sizing roller, for packaging dyeing and resin processing.

3. Roll surface and adhesive coating machine for packaging adhesives.

4. Used to seal the friction surface between the hopper and the guide rail.

5. Used to encapsulate non-sticky and smooth parts.

6. It is used for the surface of precision pressing roller for packaging dyeing and resin processing.

7. Used in packaging, thermoplastics, compounding, sealing heat sealing, electronic and electrical industries.
