Just an FYI Upate for the Chem Majors out there. 
Found my info packet on Tenite, also commonly known as Tenite Acetate, a Cellulose Acetate compound.
Max Temp for Short Durations = 180°F, 120°F long term (but not years stored in an attic or basement!)
Heat of Deflection (start of deformation) = 52-105°C (125.6 - 221°F)
My attic at home hits 120°+ easily in the typical Chicago Summer!
Tenite starts to flow/creep at 55-95°C (131-203°F)
Even long-term heat from the tubes in a radio will do a number on
a Tenite grille or pushbuttons or knobs. Witness the Tenite Philco
pushbuttons and dial escutcheons that disintegrate on the 41 and 42
model high tube count consoles.
