High Temperature Thermoplastics Achieve Higher Performance with LFT Process from PlastiComp
WINONA, MINN., USA — PlastiComp boosts properties of high-temperature polymers such as PPS, PES, PEI and PEEK, with proprietary long fiber technology. PlastiComp, Inc. announced the successful application of its long fiber thermoplastic (LFT) technology to high temperature polymers such as PPS, PES, PEI, and PEEK reinforced with carbon fibers. These new composite materials have potential for further penetration into traditional metal applications requiring very high modulus.
“Our proprietary technologies for the hot melt impregnation of the reinforcing fibers with high temperature polymers, and subsequent consolidation into molded parts yield tensile modulus values of 4-6 Msi,” explains Eric Wollan, PlastiComp’s Chief Operating Officer. “Through tailored fiber weight-fractions (40-50%) and long fiber-length retention in the molded parts we have attained a balance of properties for mechanical performance at elevated temperatures.”
According to laboratory testing, high-temperature polymers achieve higher performance with the PlastiComp LFT process. The table on page 2 demonstrates the favorable properties of Long Carbon-Fiber reinforced PES and high-impact Nylon 6,6 from PlastiComp.
“After several years in composite applications at prior technology firms, I am excited about the capabilities of the PlastiComp process to bridge the gap between composites and metals. It is well suited to a wide range of fiber-resin combinations. It can be seamlessly integrated with existing production methods such as injection and extrusion-compression molding and filament winding.”
PlastiComp’s new high-performance materials are targeted for metal replacement in military, industrial, and aerospace applications. In addition to light-weighting, the materials can also be customized for EMI shielding and thermal properties.
