Detailed Product Description: | Its friction coefficient is extremely small, only 1/5 of polyethylene, which is an important feature of perfluorocarbon surface. Also, because the fluorine - intermolecular forces between the carbon chain is very low, so the PTFE has not sticky. Polytetrafluoroethylene in a wide temperature range of -196 ~ 260 ℃ excellent mechanical properties are maintained, one of the characteristics perfluorocarbon polymer is not brittle at low temperatures. The reason is difficult to stick PTFE, mainly the following reasons: First, low surface energy, the critical surface tension is generally only 31 to 34 dyne / cm. Due to the low surface energy, contact angle, not fully wet adhesive PTFE, thereby not well adhered to the PTFE; second, the degree of crystallinity large cutting boards tetrafluoroethylene PTFE molded rod, good chemical stability, PTFE swelling and dissolution will be more difficult than the non-crystalline polymer, when the adhesive is applied to the surface of polytetrafluoroethylene PTFE, difficult to place into a chain polymer molecular chain domain spreading and intertwining temperature plastic king PTFE material, can not form a strong adhesion; third, PTFE structure is highly symmetrical, also belong to the non-polar polymers. The adhesive is adsorbed on the surface of PTFE PTFE gasket PTFE gasket processed by van der Waals forces (intermolecular forces) caused by van der Waals forces comprising orienting force, induced force and dispersion forces. For non-polar polymer surface, do not have to form an alignment force and the force induced conditions, but can only form weak dispersion forces, and thus the poor adhesion properties. Tetrafluoroethylene board board processing PTFE, PTFE, Tianjin, Tianjin three by three plastic Limited. Three Plastic Co., Ltd. Tianjin (www.tjzsxszp.com) strong, credible, in Tianjin plastic plate (sheet, section), rods and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Tianjin three and you work into the brilliant, for a better future! |
