Ryton PPS bearing grade must change significantly at very high temperatures, above 300 C
Where can I get data on mechanical properties for this temperature ?

Nothing useful from polymer supplier was forthcoming.
Does this material degrade gracefully, get soft or turn to ??
I need only modes strength at temperature and have only minimal loading.



 
Cheveron was non-responsive
if RYTON only "softens" at up to 350C, my application as a thermally insulating support for a heatshield in a zero g vacuum (space) should suffice.
thanks for response
Some additional testing will be required (but not at zero g)
the bearing grade (carbon filled) provides electrical conductivity I need
 
It melts around 285ºC so your bearing will be runny.
