Understanding PEEK 450CA20: Material Properties Explained

Before diving into procurement decisions, let's establish what PEEK 450CA20 actually is. PEEK (Polyether Ether Ketone) is a high-performance thermoplastic known for exceptional mechanical strength, chemical resistance, and thermal stability. The 450CA20 designation indicates a specific grade containing 20% carbon fiber reinforcement, which fundamentally changes the material's properties compared to unfilled PEEK.

The carbon fiber addition serves two primary purposes: it significantly improves mechanical strength and stiffness while also providing electrical conductivity. This conductivity is what makes 450CA20 suitable for ESD-safe applications. The volume resistivity of approximately 10^5 ohm-cm places it in the conductive range, allowing static charges to dissipate safely rather than building up to dangerous levels ^[2].

The thermal performance is particularly noteworthy. With a heat deflection temperature of 315°C, PEEK 450CA20 maintains its mechanical properties in environments where most engineering plastics would soften or fail. This makes it invaluable for aerospace applications where components may experience extreme temperature variations during flight cycles.

PEEK 450CA20 is a 20% carbon fibre reinforced grade of PEEK. Typical applications are for systems requiring higher strength and stiffness with excellent wear resistance and low coefficient of thermal expansion. It is chemically resistant to a wide range of chemicals and has good hydrolysis resistance ^[4].

Electrical Properties: What Makes It ESD-Safe

ESD (Electrostatic Discharge) protection is critical in aerospace, semiconductor manufacturing, and medical device applications. A static discharge of just a few hundred volts can damage sensitive electronic components or ignite flammable atmospheres. Understanding how PEEK 450CA20 achieves ESD safety helps buyers specify the right material for their needs.

Materials are typically classified by their volume resistivity: conductive materials (10^0 to 10^5 ohm-cm), dissipative materials (10^5 to 10^12 ohm-cm), and insulative materials (10^12+ ohm-cm). PEEK 450CA20's 20% carbon fiber content brings it into the conductive-to-dissipative transition range, allowing charges to flow to ground rather than accumulating on the surface ^[2].
