Carbon Fiber PPS

Carbon fiber PPS combines a semi-crystalline PPS base with carbon fiber reinforcement, significantly increasing tensile strength and stiffness while improving dimensional stability. It maintains mechanical integrity at elevated temperatures – up to a 220-260 °C range depending on formulation – and offers exceptional resistance to fuels, solvents, and acids under normal operating conditions, a level of chemical resistance rivaled among plastics only by PTFE. Unfilled PPS is inherently flame retardant and reliably achieves a UL94 V-0 rating without additives; however, whether the carbon-fiber-reinforced grade retains this exact rating can vary by manufacturer. Its low moisture absorption and strong stiffness-to-weight ratio make it a compelling lightweight option for tooling, though its moderate impact toughness makes it more brittle than materials like nylon or polycarbonate, especially in thin-walled or stress-concentrated designs. Carbon fiber PPS suits industrial jigs and fixtures, high-temperature tooling, and rigid structural components in electronics or automotive applications.
