Ensinger Tecapeek® ST PolyEtherKetoneEtherKetoneKetone, Unreinforced
Categories:	Polymer; Thermoplastic; Polyketone; Polyetherketoneetherketoneketone (PEKEKK), Wear Resistant
Material Notes:	TECAPEEK® ST is a multipurpose semi-crystalline 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 temperatures High heat distortion temperature Excellent chemical resistance Low moisture absorption Electrically insulating Easy to machine (unfilled) Good dimensional stability High purity Target 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.
