Application

Poly(tetrafluoroethylene) powder, with a particle size greater than 40 μm, serves various purposes due to its unique properties. This white powder, characterized by a slippery feel, is often utilized as a bulking agent and is included in cosmetic formulations to enhance the texture and spreadability of products. Composed of long chains of carbon atoms surrounded by fluorine atoms, PTFE is highly stable, resistant to heat, insoluble, and chemically inert. These properties stem from the strong fluorine-to-carbon bonds and the repellent nature of fluorine atoms, which contribute to PTFE's low coefficient of friction, making it difficult for substances to adhere to its surface. Furthermore, PTFE's resistance to extreme heat and chemical exposure makes it suitable for applications requiring durability, such as in bearings, valve seats, gaskets, coatings, and tubing. It can also be used for coating objects to prevent adhesion, and its excellent electrical properties make it an ideal dielectric material in high-temperature environments. Adjustments, such as the incorporation of fillers, can modify PTFE's mechanical and thermal properties.
