Plastic Condensate Pans melting or catching on fire when used with a furnace

Does anyone have any first hand knowledge of the evolution of plastic condensate pans and issues with them melting? It seems in the late 90's there was a black plastic pan but lately there is a grey almost fiberglass like pan being used. Can anyone share any experience with a furnace that caught on fire because of the melted plastic pan?
