Heating Vinyls / PVC Materials and Toxic Dioxins
Where can I go to get expert advice on heating Vinyl/PVC Products past the heat range listed on the data sheet?
I am butting heads with someone right now regarding heating "Sign" vinyl to 300 plus degrees in a heat press when the data sheet gives an upper range of 150 degrees. From what I have read and have been told, dioxins will be released if you heat vinyls past their heat range. This could be a huge health risk if the heat press is heating up sign vinyl in smaller rooms or offices.
The topic gets confusing when car wraps are done all the time by using heating torches, etc... I have heard that people that do car wrap are aware of dioxins being released but are less concerned because usually a car wrap is done in out in an open area.
To add to the confusion, some vinyls are meant to handle higher temperatures like heat press vinyl for apparel so the assumption is being made, by this person, that it's OK to heat press all vinyls now.....
This person is also saying that dioxins are only released when vinyl is burned like in a laser but again I have read that simply heating vinyl will release dioxins.
I made it to a couple different forums and it seams people are split right down the middle on the topic. Half the people say relax/no big deal and the other half get really wound up over it saying this is a very toxic thing to do!
Are there any experts on this topic here? Or what have you heard?
Thank you,
