What are the benefits of using PTFE sheets?

Polytetrafluoroethylene sheet is of course very common in our life. Because its advantages are more prominent, so the people who choose to use it are also more. Today also take this opportunity to introduce you to the benefits of using PTFE sheet? If you want to know, you should take a look at it.

We need to understand the basic information before the use of PTFE sheet is more, after all, the knowledge involved in a lot. For example, PTFE plate has a wide range of applications in both high and low temperatures. Can be used for a long time in the range of -180 ℃ ~ 250 ℃; and the product also has excellent chemical stability. Strong acid, strong alkali, strong oxidizer and other corrosive media can not have any effect on it; high electrical insulation. Unaffected by environmental conditions and frequency, is a class C insulating material; good lubricity. After adding various types of filler materials, hardness and wear resistance increase, is the ideal material for oil-free lubrication; also has good resistance to atmospheric aging properties. Exposed to the atmosphere for many years, the surface and its properties remain unchanged. PTFE plate also has physiological inertia, as artificial blood vessels and organs, long-term implantation and no adverse reactions. Atmospheric aging resistance: radiation resistance, low permeability: long-term exposure to the atmosphere, the surface and its properties remain unchanged. Non-flammable. Because its limiting oxygen index is below 90. Acid and alkali resistance: insoluble in strong acids, alkalis and organic solvents. Oxidation resistance: it can resist the corrosion of strong oxidizing agents.

PTFE sheets are used as electrical insulators, sealing and anti-adhesion materials. The working temperature is -180°C to 250°C. It has a low coefficient of friction in plastics and is an ideal oil-free lubricant. PTFE sheet is virtually impervious to corrosion by any chemical agents except molten alkali metals. For example, it is boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid and even aqua regia, its weight and properties are unchanged, and it is almost insoluble in all solvents. It has a low coefficient of friction among all known solid materials, and PTFE is particularly smooth, even compared to ice. It has a low dielectric constant and dielectric loss over a wide frequency range, and high breakdown voltage, volume resistance and arc resistance. In particular, it can also be degraded by high-energy radiation, which significantly reduces the electrical and mechanical properties of the polymer. Applications PTFE can be molded by compression or extrusion; PTFE sheets can also be made into aqueous dispersions, so it is now mainly used for coating, impregnation, or manufacturing fibers. PTFE is widely used as high and low temperature resistant places in atomic energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, food and other industries.
