PEEK plastic material has excellent dimensional stability, which is very important for some applications. Changes in environmental conditions such as temperature and humidity have little effect on the size of PEEK parts, which can meet the use requirements under conditions with relatively high dimensional accuracy requirements. 1.PEEK plastic raw materials have a small shrinkage rate during injection molding, which is very beneficial for controlling the dimensional tolerance range of PEEK injection molded parts, making the dimensional accuracy of PEEK parts much higher than that of general plastics; 2. The thermal expansion coefficient is small. With the change of temperature (which can be caused by the change of ambient temperature or the friction heat generated during operation), the dimensional change of PEEK parts is very small; 3. Good dimensional stability. The dimensional stability of plastics refers to the dimensional stability of engineering plastic products during use or storage. This dimensional change is mainly caused by the increase of the activation energy of the polymer molecules, which causes the chain segments to have a certain degree of curling; 4.PEEK has outstanding resistance to thermal hydrolysis. It has very low water absorption in high temperature and high humidity environments, and will not have the situation where the dimensional changes are obvious due to water absorption like general plastics such as nylon; http://www.chinaPEEK.com If you have needs, you can visit our company’s official website.
