產(chǎn)品說(shuō)明:
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.
Target industries for TECAPEEK® ST are Oil and Gas, Semiconductor, Chemical and
Automotive, crude petroleum extrb and drilling. Possible applications
include turbocharger impellers, seal rings and other down hole parts, gears,
and test sockets.
