What is the PTFE

Polytetrafluoroethylene , the English abbreviation for PTFE, brand name Teflon ®, is a transliteration of the Teflon. materials of the product is often called "non-stick coatings"; All the hydrogen atoms are synthetic polymer material instead of using fluoride in polyethylene. This material with acid and alkali resistance, resistance to various organic solvents, and practically insoluble in all solvents. Meanwhile, PTFE has the characteristics of high temperature, its very low friction coefficient, can be used to lubricate the rest, is an ideal coating for inner tubes. For example, hydraulic hose SAE 100 R14


1, non-stick: almost all the material is not with the PTFE coating adhesion. Very thin films also show good non-sticking properties.

2, heat resistance: Teflon coating has excellent heat resistance and low temperature characteristics. Short time can be high temperature to 300 , generally between 240 ~ 260 can be used continuously, with significant thermal stability, it can work in the freezing temperature without embrittlement, at high temperatures do not melt.

3, sliding: Teflon coating has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.05-0.15.

4, moisture resistance: PTFE surface is not coated with water and oil, the production operation is not easy to dip solution, such as sticky with a small amount of dirt, a simple wipe to remove. Downtime is short, saving hours and improving work efficiency.

5, wear resistance: under high load, with excellent wear resistance. In a certain load, with wear and non-adhesion of the dual advantages.

6, corrosion resistance: Teflon is almost free from drug erosion, can withstand the addition of molten alkali metals, fluorinated media and higher than 300 sodium hydroxide all the strong acid (including aqua regia), strong oxidants, reduction Agents and a variety of organic solvents, can protect the parts from any kind of chemical corrosion.
