Ok, in looking at the outgassing of polystyrene (pink/blue board), I came across this stuff.
The "outgassing" hazard might not actually exist in the way commonly stated. Surfboard makers, signmakers, and aircraft builders have spread a "myth" of outgassing. It's actually delamination of their applied coverings from silicone used on the *outside* of the pink/blue board. Epoxy, tape, and fiberglass mixed with adhesives of many types do not stick to silicone. Now, the environmentalists complain about raw Styrene exposure of the *factory* workers. And the exposure of nearby populations to the "offgassing" from the plants *making* the polystyrene. The "offgassing" from these plants/factories also mess with the ozone layer. This is the true "offgassing". Also, if you cut pink/blue polystyrene with a hot knife, you are remelting the plastic. Thereby releasing styrene "gases" locally in your face. By itself, pink/blue board should not emit anything just sitting there. I would still like to see an exact study document that proves "spontaneous outgassing" from pink/blue polystyrene. That may not be forthcoming, for the reasons stated above. -- You received this message because you are subscribed to the Google Groups "hexayurt" group.
