Material Characteristics and Application of Teflon Bolts

Dec 14,2020 / Industry News, News / Author: ShengKui

Telfon stud bolts are used to fasten and connect two parts with through holes. It is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents.

At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used as a way of lubrication, and it has become an ideal coating for non-stick pots and water pipes.

Features: non-sticky, the coating surface has very low surface tension, thus showing strong non-stickiness. Very few solid matter can stick to the coating. Although the gelatinous substance may adhere to its surface to some extent, most materials are easy to clean on its surface. 2. Low coefficient of friction: Teflon has a coefficient of friction in all solid materials, which ranges from 0.05 to 0.2, depending on the surface pressure, sliding speed and what coating is used.

The outstanding sliding performance of Telfon stud bolts has been widely recognized. It has a very low coefficient of friction when it comes into contact with most materials, which mainly depends on the load, sliding speed and the type of Teflon paint used, generally 0.05-0.20 Within range. In the production of metals, plastics, paper, and food products, Teflon coating makes their transportation easier. The surface treated with Teflon has a dry lubricating effect. Therefore, it is often applied to mechanical parts that require high friction coefficients. While reducing the friction coefficient and increasing wear resistance, it can also be self-lubricating.
