PTFE (Polytetrafluoroethylene) and PEEK (Polyether Ether Ketone) represent the pinnacle of engineering plastic technology. Both are classified as high-performance polymers, capable of operating in extreme environments that would destroy conventional engineering plastics.
PTFE Properties
PTFE offers virtually complete chemical resistance (inert against all common chemicals except molten alkali metals and fluorine), temperature range from -200°C to +260°C, coefficient of friction of 0.05-0.10 (lowest of any solid material), and excellent electrical insulation properties.
PEEK Properties
PEEK provides tensile strength of 90-100 MPa (3-5x stronger than PTFE), temperature resistance up to 250°C continuous, excellent creep resistance at elevated temperatures, and radiation resistance for demanding applications. Carbon fiber reinforced PEEK reaches 200+ MPa tensile strength.
選定ガイド
Choose PTFE for chemical resistance and low friction. Choose PEEK for mechanical strength at temperature. For engineering applications, our PA66-CF30 provides excellent strength-to-weight ratio.
