Which wear resistance is better, polyurethane or nylon?
Thread Content
I saw that many materials require wear resistance, such as nylon cords for car tires, nylon socks for socks, polyurethane for hydrocyclones, polyurethane for so-called tendon bottoms, etc., please tell me: Is polyurethane or nylon better for wear resistance? Thank you! This post was last edited by QXZ-1966 on 2009-2-22 09:12 ]
How should I put it, even if it is a wear-resistant requirement, the choice of materials is not only a matter of wear resistance, but also depends on the specific application.
I agree with what Floor 2 said, the key depends on the application environment.
Just considering the difficulty of grinding, of course nylon is better. Polyurethane has advantages in high temperature resistance and elasticity. The price of polyurethane is also expensive.
It depends on the application in which aspect each has its own advantages and disadvantages, which can be improved through modification.
It should start from the actual application, and the wear resistance of the two is different.
In terms of high temperature resistance, nylon should be better than polyurethane in most cases (it also depends on the type of nylon/polyurethane). Choosing polyurethane generally depends on its good wear resistance and elasticity, as well as a certain degree of heat resistance. If you focus on the wear resistance of materials, you can generally consider PTFE, PPS, POM, PI, PA, PU ； The specific choice of materials must be determined based on the specific use environment and functional requirements, such as the use temperature range, possible exposure to chemical substances, mechanical properties, etc.
