牌号简介	分散型聚四氟乙烯树脂（PTFE）质量标准：Q/321200GDH009-2011参考标准：HG/T3028-1999 Dispersion PTFE Resin (PTFE) Quality Standard: Q/321200GDH009-2011 Reference Standard: HG/T3028-1999	聚四氟乙烯7A X是一种白色粉末，粒径小，体积密度高。即使在相对较低的成型压力下，聚四氟乙烯7A X的小颗粒尺寸也有助于减少空隙。高体积密度增加了从一个给定的模具或压力开口可能的成型尺寸。特氟隆聚四氟乙烯7A X是首选的大型模具，如钢坯，需要最佳的机械和电气性能。当加入填料以改变模制品的机械性能时，它也用于与填料的混合物中。由纯Teflon® PTFE 7A X制成的经过适当处理的产品具有典型的氟塑料树脂的优良性能：在260°C（500°F）下使用后的性能保持不变，在-240°C（-400°F）下的有用性能，几乎对所有工业化学品和溶剂的化学惰性，以及低摩擦和防粘表面。介电性能优异，频率和温度稳定。成型产品具有中等刚度和高延伸率。特氟隆聚四氟乙烯7A X可防止点火，不促进火焰蔓延。当被其他来源的火焰点燃时，热量的贡献很小，烟很少。与火焰情况下的行为相关的声明或数据不旨在反映实际火灾条件下该材料或任何其他材料所带来的危险。典型应用许多最终产品由聚四氟乙烯7A X的成型件制成，包括刮膜和薄片、垫圈、填料、机械密封件、桥梁或管道轴承垫、轴轴承、电绝缘体、活塞环、膨胀波纹管、隔膜和化学衬里。填料的使用提供了多种改性机械性能的选择。 Teflon ® PTFE 7A X is a white powder with small particle size and high bulk density. The small particle size of Teflon ® PTFE 7A X helps to minimize voids even at relatively low molding pressures. High bulk density increases the size of moldings possible from a given mold or press opening. Teflon ® PTFE 7A X is preferred for large moldings, such as billets, requiring optimum mechanical and electrical properties. It is also used in a mixture with fillers when they are added to modify the mechanical properties of moldings. Properly processed products made from neat Teflon ®PTFE 7A X provide the superior properties typical of the fluoroplastic resins: retention of properties after service at 260 °C (500 °F), useful properties at -240 °C (-400 °F), chemical inertness to nearly all industrial chemicals and solvents, and low friction and anti-stick surfaces. Dielectric properties are outstanding and stable with frequency and temperature. Molded products have moderate stiffness and high elongation. Teflon ® PTFE 7A X resists ignition and does not promote flame spread. When ignited by flame from other sources, the contribution of heat is small and with little smoke. Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions. Typical Applications Many end products are fabricated from moldings of Teflon ® PTFE 7A X, including skived film and sheet, gaskets, packings, mechanical seals, bridge or pipeline bearing pads, shaft bearings, electrical insulators, piston rings, expansion bellows, diaphragms, and chemical linings. The use of fillers provides a wide choice of modified mechanical properties.
