Material Notes:
TECAPEEK® ST is a multipurpose semi-crystaline material from the polyaryletherketone family based on PEKEKK that features improved mechanical properties at higher temperatures. The benefits of TECAPEEK® ST compared to standard TECAPEEK® are that of a higher heat distortion temperature (HDT), better strength and stiffness of machined components and a higher flexural strength combined with a higher glass transition point.Excellent mechanical properties at higher temperaturesHigh heat distortion temperatureExcellent chemical resistanceLow moisture absorptionElectrically insulatingEasy to machine (unfilled)Good dimensional stabilityHigh purityTarget industries for TECAPEEK® ST are Oil and Gas, Semiconductor, Chemical and Automotive, crude petroleum extraction and drilling. Possible applications include turbocharger impellers, seal rings and other down hole parts, gears, and test sockets.Information Provided by Ensinger Inc.
