polarizing filters

I would like to ask if any one knows where I could buy a pair of high
optical quality heat resistant polarizing filters. I am building a pair
of 35-mm film projectors for 3-d projection. They have lamp houses of
5,000w  xenon arc.
I had tried Hoya polarizing filters, they lasted 5 seconds and the 
centre part turns yellow and becomes transparent.
I used plastic ones from Reel 3d enterprises. They lasted as long as no 
direct bare xenon light focused on them, but , are there any higher
quality ones ?
