TECAPEEK ST
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 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.
