Good day everyone,

I'm looking for a polyimide called HTR-3.  It was distributed as
Selectilux HTR-3 by Merck in the late 80's and then as Probimide HTR-3
200 by OCG more recently.  It doesn't look like Olin carries it now
though?  If anyone knows of a supplier currently carrying the HTR-3
series polyimide, I would much appreciate hearing about it.

I am strongly considering the possibility that the HTR-3 series may no
longer be in production because it is quite old.  Does anyone know of
another polyimide with large thermal shrinkage during curing (>50%) and
a high coefficient of thermal expansion (>50 ppm/degree C)?  If so,
please let me know.

Thanks,

Mike Colgan
