The characteristics of the PTFE tape

The versatile performance properties of PTFE including non-stick release, high temperature resistance, water and chemical resistance, and dielectric strength make The characteristics of the PTFE tape useful in a variety of applications. These properties contribute to enhanced performance where physical properties are important.

Physical properties

The characteristics of the PTFE tape are relatively soft. Has very low surface energy. In current practical applications, many liquid raw material belts are used instead of solid raw material belts. Liquid raw material thread sealant has the characteristics of high bonding strength, good sealing performance, corrosion resistance, high temperature resistance, and aging resistance. It is the most advanced thread sealant at present, with precise filtering device and quick installation. Widely used in thread sealing and locking of industrial and civil pipelines such as fire protection, shipbuilding, natural gas, tap water, instrumentation, air conditioning, air pipes, oil pipes, hydraulic pipes, etc. Nonflammability: limiting oxygen index below 90.

Chemical properties

Insulation: not affected by the 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: small temperature change, wide working temperature range, working temperature -190~260°C.
Self-lubricating: It has the smallest friction coefficient among plastics and is an ideal oil-free lubricating material.
Non-adhesive surface: Any known solid material cannot adhere to its surface, and it is the solid material with the smallest surface energy.
Atmospheric aging resistance: radiation resistance, low permeability: long-term exposure to the atmosphere, the surface and performance remain unchanged.
