Introduction：In general, the accuracy of PTFE product is not easy to control because its coefficient of linear expansion is higher than that of metals, and its one of volume transition temperature is around room temperature causes volume changes approximately 1 to 2%. Moreover, thin-walled PTFE products are known to be difficult to machining because not only PTFE is flexible and elastic material, but also residual stress remains after molding sometimes deform due to frictional heat generated during the machining process or due to aging after machining. Such deformation could influence dimensional accuracy.
PTFE is commonly used for hydraulic liner seals in just about every industry that uses them. From guide rings to chevron sets, PTFE hydraulic linear seals have a reputation for durability and excellent tribological performance.
In this blog post, we are going to discuss why PTFE is so popular for hydraulic linear seals.
