[Dongsheng insulation material to recommend the star product - PTFE plate PTFE plate rod rods] Description: self-lubricating: has the smallest plastic friction coefficient imported synthetic stone, is the ideal oil-free materials. The surface is not sticky: known solid materials can not adhere to the surface, is a minimum surface energy of the solid material. Resistance to atmospheric aging, radiation resistance and low permeability. [Dongsheng insulation material to recommend the star product - stick PTFE plate PTFE plate rod introduction]: but the formation of a helical twist chain synthetic slate, a fluorine atom, covering almost the entire surface of the polymer chain. This molecular structure explains the various properties of PTFE synthetic black slate, no change in weight and properties, it is almost insoluble in all solvents and only slightly soluble at above 300 ℃ full alkanes (about 0.1g / 100g ). Black synthetic slate, synthetic slate Beijing, Tianjin and synthetic stone preferred by Dongsheng Dongsheng Insulation Materials Co., Ltd. Tianjin. Tianjin Dongsheng Insulation Materials Co.
