Teflon can be compressed or extruded; It can also be made into water dispersion for coating, dipping or fiber. Teflon is widely used in industries such as atomic energy, aerospace, electronics, electrical, chemical industry, machinery, instruments, meters, construction, textile, food and so on as high and low temperature resistant, corrosion resistant materials, insulation material, anti-stick coating and so on.

The main function of bulking Teflon tape uses 100% polytetrafluoroethylene as raw material, which has a network bulking structure composed of fine long fibers and knots. The bulge is Teflon tape and has the characteristics of good toughness, high longitudinal strength and easy transverse deformation. It is an ideal material for disc and thread back seat. However, it cannot be used in contact with high concentration oxygen or liquid oxygen.

Insulation: not affected by environment and frequency, the volume resistance can reach 1018 Ohm · cm, the dielectric loss is small, and the breakdown voltage is high.

High and low temperature resistance: the influence on temperature does not change much, the temperature domain range is wide, and the temperature can be used at-190 ~ 260℃.

Self-lubrication: it has the smallest friction coefficient among plastics and is an ideal oil-free lubricatoin material.

Surface non-stickiness: known solid materials cannot adhere to the surface, which is a solid material with the smallest surface energy.

Atmospheric Aging resistance, radiation resistance and low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.

Incombustibility: the oxygen limiting index is below 90.

The mechanical properties of polytetrafluoroethylene are relatively soft. Very low surface energy.

In practical applications, many liquid Teflon tape are used to replace solid Teflon tape. Liquid raw materials have the characteristics of high bonding strength, good sealing performance, corrosion resistance, high temperature resistance, aging resistance, etc. Precision filter device, fast installation, is currently the most advanced thread sealant. Widely used in fire fighting, shipbuilding, natural gas, tap water, instrument, air conditioning, air pipe, oil pipe, hydraulic pipe and other industrial and civil pipeline threads
