| 牌号简介 |
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. |
大金聚四氟乙烯（聚四氟乙烯）成型粉末是优良的，精细切割树脂，非常适合各种苛刻的化学，机械，电气和非黏性表面应用。这些聚四氟乙烯树脂完全氟化，具有所有氟聚合物的最佳热、电和化学性能，其连续工作额定值为500°F（260°C）。Daikin聚四氟乙烯成型粉末有均聚物和改良的细切削等级。Daikin聚四氟乙烯成型粉末可在260°C（500°F）以下的温度下连续使用，在更高的温度下可短期使用。它们还具有优异的低温强度。Daikin聚四氟乙烯成型粉完全惰性，除高温、高压元素氟气、熔融碱金属和三氟化氯外，其他所有化学品均能对其进行侵蚀。非极性分子结构使大金聚四氟乙烯成型粉成为高频绝缘材料的理想选择。在较宽的频率范围内，介电常数和损耗因数均较低。在正常使用条件下，大金聚四氟乙烯成型粉具有任何固体材料的最低摩擦系数。而且，这些产品的不粘特性阻止了大多数材料粘附在它们上面。化学/机械填料、垫片、隔膜、波纹管、耐腐蚀衬里、管道部件、泵部件、O形圈、V形圈、衬套、滑动轴承等。电气/其他绝缘刮削带、绝缘套管、端子、连接器、插座、垫片、电子零件、实验室设备等。 Daikin PTFE (polytetrafluoroethylene) molding powders are excellent, fine cut resins, well suited for a variety of demanding chemical, mechanical, electrical and non-stick surface applications. These PTFE resins are fully fluorinated and have the best thermal, electrical, and chemical properties of all fluoropolymers with a continuous service rating of 500°F (260°C). Daikin PTFE molding powders are available in homopolymer and modified fine cut grades. Daikin PTFE molding powders can be used continuously at temperatures up to 260°C (500°F) and for short periods of time at higher temperatures. They also possess excellent low temperature strength. Daikin PTFE molding powders are completely inert to attack by all chemicals except hightemperature, high-pressure elemental fluorine gas, molten alkaline metals and chlorine trifluoride. The non-polar molecular structure makes Daikin PTFE molding powders ideal for use as high-frequency insulating material. The dielectric constant and dissipation factor are uniformly low over a wide frequency range. Under ordinary conditions of use, Daikin PTFE molding powders possess the lowest coefficient of friction of any solid material. Also, the non-stick properties of these products prevent most materials from adhering to them. Chemical/Mechanical—Packings, gaskets, diaphragms, bellows, corrosion-resistant linings, piping components, pump parts, O-rings, V-rings, bushings, slide bearings, etc. Electrical/Other—Insulating skived tape, insulating sleeves, terminals, connectors, sockets, spacers, electronic parts, laboratory equipment, etc. |
