What is Teflon tape
Teflon tape is also called Teflon tape, or Teflon adhesive tape. First, glass fiber is used as the base cloth, coated with Teflon emulsion and dried to make Teflon fiberglass cloth. It is a kind of high temperature resistant adhesive tape made of silicone adhesive after secondary coating.
It is a new high-performance, multi-purpose composite material product. The strap has a smooth surface, good adhesion resistance, chemical resistance and high temperature resistance, as well as excellent insulation properties.

Application range of Teflon tape
Various types of high-temperature rollers are used for pasting and covering, heating plates, and removing films; heat-sealing food, medicines and plastic bags. It can also be used in industries such as sizing machine drums, thermoplastic demoulding, etc. It can be used repeatedly and is easy to replace. Suitable for other surface treatments that require anti-sticking, corrosion resistance and high temperature resistance. It is used in packaging, thermoplastic, composite, sealing heat sealing, electronic and electrical industries, where anti-sticking heat sealing, corrosion-resistant insulation and other parts need to be pasted, and has the function of repeated pasting. The fabric-reinforced PTFE Teflon tape has the characteristics of high strength and can be used in the drum of sizing machine, thermoplastic demoulding and other industries. It can be used repeatedly and is easy to replace. It can be directly pasted on various large planes and regular curved surfaces (such as rollers), and the operation is simple. Eliminates restrictions on spraying PTFE materials that require professional equipment, special processes, and must be transported to a professional spraying factory for processing. The long-term use temperature of the product can reach 260℃.

1. Good thermal performance (continuous use temperature above 260°C), the maximum temperature can reach 300°. It can be used safely even on overheated heaters;
2. Good viscosity, the "dregs" of the melted packaging film will not stick to the heater;
3. Excellent affinity;
4. Good line stability, good durability and easy maintenance.

Teflon tape application examples
1. Heat-sealing and cutting machines and high-speed heat-sealing machines in the food and drug plastic packaging industry;
2. Anti-sticking treatment on the surface of the drying cylinder of the dryer; anti-sticking treatment on the surface of the laminating machine drying cylinder; anti-sticking treatment on the surface of the guide roller and pressure roller; anti-sticking treatment on the surface of the paper machine drying cylinder;
3. The application of anti-sticking glue, anti-sticking color, and reducing friction on the surface of various workpieces.

Teflon tape performance characteristics
1. Used between low temperature -196℃ and high temperature 300℃, with weather resistance and anti-aging. After practical application, if placed at a high temperature of 250°C for 200 days, 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 the 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. Can withstand almost all pharmaceutical items;
5. It has high insulation performance (small dielectric constant: 2.6, tangent below 0.0025), anti-ultraviolet, anti-static;
6. Fire and flame retardant;
7. Easy to use and long service life.
