What are the reasons for the excellent sliding properties of fluoropolymer? We will introduce the characteristics of fluoropolymer PTFE, focusing on its lubricity and low friction. *Downloadable materials available.
■Low Friction and Sliding Properties of Fluoropolymer (PTFE) Fluoropolymers have a low coefficient of friction and are used for solid lubrication. PTFE is structured such that fluorine atoms surround carbon atoms without gaps. The free energy of the fluorine atoms on the molecular surface is low, and the molecules have the characteristic of extremely low polarity in their target structure. The low coefficient of friction of PTFE is believed to be influenced by this type of molecular structure. ■Reasons for the Low Coefficient of Friction of Fluoropolymer PTFE - The strong atomic bonds within PTFE molecules reduce the intermolecular forces with the contacting material. - Friction (sliding) causes PTFE molecules to adhere slightly to the counterpart material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with minimal irregularities. - The orientation of PTFE molecules makes it easier to alleviate frictional resistance. For these reasons, fluoropolymer PTFE is considered to have excellent lubricating properties. For more details, please download the materials or contact us.
basic information
■Solid Lubrication with Fluoropolymer Coating Fluoropolymer coating can create a film of fluoropolymer on surfaces such as metals. By applying a fluoropolymer coating, the characteristics of the fluoropolymer can be utilized in components and equipment, making products smoother and providing lubrication to parts of devices, which is expected to improve productivity and prevent process troubles.
