Processing and application of modified (filled) PTFE products

In order to improve the dimensional stability, thermal conductivity, hardness, abrasion resistance, creep resistance, compression resistance and reduce the linear expansion coefficient of PTFE products, we can use different fillers to be filled in PTFE resin after processing. The solution is to modify (fill) PTFE. But if we want to improve the tensile strength, fatigue resistance, dielectric properties and other properties of PTFE, we can only use special equipment and special processes to achieve it.

The processing of modified (filled) PTFE products generally refers to the addition of inorganic substances, metal powders or high molecular polymers to PTFE resin, and the modified (filled) PTFE products are prepared by mixing, preforming, and sintering. At present, the processing technology of modified (filled) PTFE products has matured day by day, and the application of its formula has become more and more targeted. Modified (filled) PTFE products, while maintaining the extremely low coefficient of friction of PTFE products, its wear resistance is greatly improved, especially the characteristic of not damaging the mating parts, which significantly improves the performance of dynamic friction seals. Key components The service life and safety of the product are effectively guaranteed.

Modified (filled) PTFE products include not only filled modified products, but also processed modified products. This kind of modified products mainly include PTFE film, PTFE tape for seamless wrapping of special cables, PTFE diaphragm, etc. The processing methods of these products are based on the basic PTFE processing methods, and the special processing methods are determined after repeated trials, research and verification.
