PTFE Water Tape is a fluorocarbon solid consisting of carbon and fluorine. It has water repellent qualities, as well as low coefficient of friction against solids. It is best known by its brand name Teflon. It is commonly used in non-stick coating for pans and other cookware Its non-reactive, and often used in containers and pipework for reactive and corrosive chemicals. PTFE is a thermoplastic with a high melting point compared to other plastics and rubbers. It has great dielectric properties making it suitable for insulation in cables and connector assemblies.

Seals made from PTFE are used when other materials cannot meet the requirements for projects with high temperature ranges, chemical resistance or friction wear and tear, PTFE seals are suitable for use in harsh environments with operational temperatures in excess of 200 centigrade. It has great qualities when considered for high-speed dynamic applications or extreme pressures.

Properties of PTFE

  • Low Friction Capabilities
  • Excellent chemical resistance
  • Reduce sticking capabilities
  • Does not age with time
  • No explosive decompression
  • No swelling due to moisture
  • Safe in vacuum conditions
  • High operational temperature ranges
  • Excellent electrical properties

PTFE is almost limitless in possible application usage. Due to its chemical resistance and high service temperature ranges. it has been used in high performance bearing and bushings. It is not susceptible to saturation of high-pressure gas, swelling due to moisture and low coefficient of friction. This makes it ideal for application including pneumatic seals, hydraulic cylinders, high speed applications, aerospace and energy, oil, & gas. Its properties place it in a league of its own in gasket and seal materials where extreme system conditions render other materials moot.

Uses of PTFE

PTFE contains a components like carbon and fluorine. This condition gives PTFE a high molecular weight that provides several advantages. It is water resistant and resistant to substances containing water. It also resists friction solid and is highly heat resistant.

This allows PTFE PTFE to be used as a component of gears, bearings, and slide plates. PTFE does not begin to degrade until it reaches a temperature of 662 degrees Fahrenheit.

Applications of PTFE

The non-stick properties of PTFE are so effective that not even a gecko can stick to it. For this reason, PTFE can be used on building surfaces to prevent insects from climbing walls.

PTFE’s non-stick properties have also been utilized by the dental industry for fillings to prevent them from sticking to adjacent teeth.

PTFE is also used to make containers and pipes because it is anti-corrosive, and non-reactive. This is useful for laboratories handling highly corrosive chemicals that need to be placed in glass containers. Additionally, it’s carbon-fluorine bonds give PTFE increase tensile strength.

PTFE can also be used as a lubricant for machinery. When used this way, PTFE reduces friction, energy consumption and equipment wear. One example of this is lubricant used on bicycle chains.

PTFE is also used to make gaskets because of its strength and heat resistance. It is also used as a thread seal tape for plumbing.

PTFE also has good electric insulation properties and thus it is used to insulate cables and connector assemblies. This makes it ideal for hookup wire, coaxial cable and printed circuit boards.

PTFE can also be found in consumer products such as outdoor apparel, school uniforms, footwear, insoles, orthotics.
