1. Good dimensional stability, compared with general engineering plastics, the linear expansion coefficient of phenolic fabric is lower about 1/2, compared with nylon, its water absorption is also smaller.
2. High temperature resistance, phenolic fabric has higher thermo-chemical and stability compared with commonly used engineering plastics. The long-term use temperature of general engineering plastics is about 80-90℃, while PFC can be as high as 120-130℃, which expanding the range of use.
3. Good wear resistance, compared with bronze, phenolic fabric’s hardness is lower, has good wear resistance, easy to close, and will not grind the shaft. As a precision bearing, the complex grinding process can be avoided.
4. High load capacity, compared with commonly used engineering plastic, phenolic fabric has higher mechanical strength, such as compressive strength, which is about 2-4 times than the for normal engineering plastics. Compared with bronze, its specific gravity is only 1/4, so it also has higher specific strength.
5. Even in the case of harsh lubrication conditions, it also has outstanding compatibility. Such as frequent opening and closing, intermittent movement, swing movement and other cases of friction between the fluid power lubricating oil film is difficult to form, it can still maximize the use of trace grease, so as to greatly extend the refueling maintenance cycle and service life.
6. Good hydrophilic properties, it can work safely in water cooling or in water for a long time under the condition of no oil, without a set of complicated lubrication sealing device.
7. Proper elastoplastic, phenolic fabric is an elastoplastic material. Compared with bronze, cast iron and other materials, it is easy to assemble, but also has the function of absorbing vibration and noise, reduce the impact force of the machine in motion, so as to delay the damage of the machine. Compared with general engineering plastics, it is not easy to produce plastic deformation and affect its supporting function.
