I doubt that there is a general answer. In any case, the heating may alter the plastic chemically, so that either it will not burn anyway, or the retardant will not stop it burning. I think you have to ask what happens with plastics A to Z with retardants 1 to 10, and get 260 answers (or not). -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
