Yeah, it's only rated to 200 degrees. I'm just going to see if it will be suitable. From the material specs it appears it will as long as the motor doesn't overheat. But hey, what's 12 degrees really...?
Here's some information on the housing material;
KYNAR PVDF
THERMAL PROPERTIES:
Melting point : 352° F

PVDF is a high molecular weight thermoplastic polymer with excellent chemical inertness. It is highly resistant to oxidizing agents and halogens and is almost completely resistant to allphatic, aromatics, alcohols, acids and chlorinated solvents. It is resistant to most acids and bases.
PROPERTIES:
Mechanically strong. High dielectric strength. Thermally stable. Resistant to low temperatures. Stable to ultraviolet and extreme weather conditions. Self-extinguishing and non-toxic.
