PEEK round bar available in natural colour. PEEK is a special technical thermoplastic that is semi-crystalline and has high chemical compatibility.
Components made of high-temperature plastic PEEK natural in round bar has a melting point of around 341°C (646°F) and may function at temperatures as high as 260°C (480°F). Because it retains its physical characteristics, such as flexural and tensile strength, at a high level despite the harsh environment, this plastic is frequently utilized in hot water or steam conditions. Products made with this plastic enables the production of parts that are lighter, stronger, and able to last longer in harsh environments.

Our information and statements reflect the current state of our knowledge and shall inform about our products and their applications. They do not assure or guarantee chemical resistance, quality of products and their merchantability in a legally binding way. Our products are not defined for use in medical or dental implants. Existing commercial patents have to be observed. The corresponding values and information are no minimum or maximum values, but guideline values that can be used primarily for comparison purposes for material selection. These values are within the normal tolerance range of product properties and do not represent guaranteed property values. Therefore they shall not be used for specification purposes. Unless otherwise noted, these values were determined by tests at reference dimensions (typically rods with diameter 40-60 mm according to DIN EN 15860) on extruded and machined specimen. As the properties depend on the dimensions of the semifinished products and the orientation in the component (esp. in reinforced grades), the material may not be used without a separate testing under individual circumstances. The customer is solely responsible for the quality and suitability of products for the application and has to test usage and processing prior to use. Technical changes reserved.
