Teflon sheet properties and uses:

In fluoroplastics, PTFE has the largest consumption and the widest range of uses. It is an important category of fluoroplastics. The chemical structure of PTFE is the replacement of all hydrogen atoms in polyethylene. In the PTFE molecule, the F atom masks the CC bond and the CF bond strength is particularly stable. It is not attacked by any chemicals other than the alkali metal and elemental fluorine.

In the PTFE molecule, the F atom is symmetrical, and the two elements in CF are covalently bonded. There is no free electron in the molecule and the entire molecule is neutral. PTFE has excellent dielectric properties because PTFE has no gram in its molecular structure, so its crystallinity is high. Because PTFE has an inert fluorine-containing outer shell, it has outstanding non-stick properties and a low coefficient of friction.

PTFE has outstanding excellent comprehensive performance, high and low temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, low friction coefficient, but its mechanical properties are not as good as other plastics. Good, no wear, low hardness, easy cold flow. Adding any filler that can withstand PTFE sintering temperature (360°C - 380°C) in PTFE, its mechanical properties can be greatly improved. At the same time, maintain other excellent properties of PTFE. The fillers include glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, and the like.

1. Low coefficient of friction, lowest in almost all solids;

2, particularly good temperature resistance;

3, strong chemical stability, almost no erosion by any chemicals;

4, the surface is not sticky;

5, excellent electrical insulation properties, a wide range of frequencies within the dielectric constant and the minimum value of 6, excellent anti-aging properties, not affected by oxygen, ozone, ultraviolet light;

7, extremely valuable incombustibility;

8. Minimal Water Absorption Because PTFE has many excellent properties, it is used in the defense industry and advanced science fields. Since civilian use began in the 20th century 50 years, people have been working hard to maintain their excellent performance under the premise of overcoming their shortcomings, developing various composite PTFE products and filled PTFE products, while seeking a variety of new The processing method makes PTFE products have wider applicability and broaden their application fields. Now PTFE has become an indispensable important material in various industries.

Teflon ball valve seat and stem seal washers are made of suspension polymerized PTFE resin. Compared with other plastics, PTFE has the features of chemical corrosion and excellent temperature resistance.
