聚四氟乙烯(PTFE)的低摩擦性能在载荷方面的应用由于有的设备的摩擦部分不宜加油润滑，比如

在润滑油脂会被溶剂溶解而失效的场合或者造纸、制药、食品、纺织等工业领域的产品需要避免润滑油

沾污， 就使填充PTFE材料成为机械设备零件无油润滑（直接承受载荷）的理想材料。这是因为该材料

的摩擦系数是已知固体材料中低的。其具体用途包括用于化工设备、造纸机械、农业机械的轴承，用

作活塞环、机床导轨、导向环；在土木建筑工程广泛用作桥梁、隧道、钢结构屋架、大型化工管道、贮

槽的支承滑块，以及用作桥梁支座和架桥转体等。

　　4、聚四氟乙烯(PTFE)在电子电气方面的应用

　　PTFE材料固有的低损耗与小介电常数使其可做成漆包线，以用于微型电机、热电偶、控制装置等；

PTFE薄膜是制造电容器、无线电绝缘衬垫、绝缘电缆、马达及变压器的理想绝缘材料，也是航空航天等

工业电子部件不可缺少的材料之一；利用氟塑料薄膜对氧气透过性大，而对水蒸汽的透过性小的这种选

择透过性，可制造氧气传感器；利用氟塑料在高温、高压下发生极向电荷偏离现象的特性，可制造麦克

风、扬声器、机器人上的零件等；利用其低折射率的特性，可制造光导纤维。

DAIKIN AMERICA, INC.

填料

产品说明：

Daikin PTFE (polytetrafluoroethylene) molding powders areexcellent, fine cut resins, well suited for a variety of demandingchemical, mechanical, electrical and non-stick surfaceapplications. These PTFE resins are fully fluorinated and have thebest thermal, electrical, and chemical properties of allfluoropolymers with a continuous service rating of 500°F (260°C).Daikin PTFE molding powders are available in homopolymer andmodified fine cut grades.

Daikin PTFE molding powders can be used continuously attemperatures up to 260°C (500°F) and for short periods of time athigher temperatures. They also possess excellent low temperaturestrength.

Daikin PTFE molding powders are completely inert to attack by allchemicals except hightemperature, high-pressure elemental fluorinegas, molten alkaline metals and chlorine trifluoride.

The non-polar molecular structure makes Daikin PTFE molding powdersideal for use as high-frequency insulating material. The dielectricconstant and dissipation factor are uniformly low over a widefrequency range.

Under ordinary conditions of use, Daikin PTFE molding powderspossess the lowest coefficient of friction of any solid material.Also, the non-stick properties of these products prevent mostmaterials 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.
