            Features of PEEK sheet

            2021-07-19

            The density of the pure PEEK sheet is 1.3g/cm3. peek polyether ether ketone is a special engineering plastic with excellent properties such as high temperature resistance, self-lubricating, easy processing and high mechanical strength. It can be manufactured and processed into various mechanical parts, such as automobile gears, oil screens, and shift start disks. Wait. If the PEEK material is added with glass fiber, carbon fiber or HPV (graphite, carbon fiber, PTFE), the density is about 1.45g/cm3.

            Features of PEEK sheet:
            1. The injection molding shrinkage rate of PEEK plastic raw materials is small, which is very good for controlling the dimensional tolerance range of PEEK injection molded parts, so that the dimensional accuracy of PEEK parts is much higher than that of general plastics;

            2. The coefficient of thermal expansion is small. With temperature changes (caused by changes in ambient temperature or frictional heat during operation), the size of the parts changes very little;
            3. Good dimensional stability. The dimensional stability of plastics refers to the dimensional stability of engineering plastic products during use or storage, because the activation energy of polymer molecules increases, which causes the chain segments to curl to a certain extent;

            4. PEEK has outstanding heat-resistant hydrolysis properties, and has low water absorption in high temperature and high humidity environments, and there will be no obvious changes in size due to water absorption of general plastics such as nylon;
