What is the Characteristics of Teflon wire?

2021-11-29
Characteristics of Teflon wire:

1. Non stick: almost all substances do not adhere to the PTFE film. Very thin films also show good non adhesion properties.

2. Heat resistance: PTFE coating has excellent heat and low temperature resistance. It can withstand high temperature to 300 ℃ in a short time, and can be used continuously at 240 ℃ ~ 260 ℃ generally. It has significant thermal stability. It can work at freezing temperature without embrittlement and melting at high temperature.

3. Sliding property: PTFE coating has low friction coefficient. The friction coefficient changes when the load slides, but the value is only between 0.05-0.15.

4. Moisture resistance: the surface of Teflon film is free from water and oil, and it is not easy to get solution during production and operation. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime, save man hours and improve work efficiency.

5. Wear resistance: it has excellent wear resistance under high load. Under certain load, it has the dual advantages of wear resistance and non adhesion.

6. Corrosion resistance: polytetrafluoroethylene is hardly eroded by drugs. It can withstand the effects of all strong acids (including aqua regia), strong oxidants, reducing agents and various organic solvents except molten alkali metals, fluorinated media and sodium hydroxide higher than 300 ℃, and can protect parts from any kind of chemical corrosion.

Self lubricity: with the smallest friction coefficient in plastics, it is an ideal oil-free lubricating material. Surface inviscid: known solid materials can not adhere to the surface. It is a solid material with the smallest surface energy.
Atmospheric aging resistance, radiation resistance and low permeability: the surface and properties remain unchanged after long-term exposure to the atmosphere.
Incombustibility: the oxygen limiting index is below 90.
Polytetrafluoroethylene is widely used in industries with high temperature resistance and high viscosity. Among them, the strongest super acid -- fluoroantimonic acid can also be preserved with it.
American AkzoNobel company has newly developed harmless and non stick materials. Because it is a secret recipe, it has not disclosed the specific production method, but claims to be absolutely safe and harmless, and has been used in the products of Calphalon, the top kitchen utensils in the United States.
