Hello,
This may not be your answer,but I know that design temperature for a plastic part in a car room,is 90 deg. C .
this is for a black plastic part during hot summer when all windiws are closed.i hope this answer help you.

In analyzing failures of fire-retardant treated plywood roofs, it was found that roof surfaces under dark shingles in open sun in the southern part of the US reached 150-160 deg F.
FRT wood is tested at that temp to establish strength degradation factors.
