wildtail97 Posted April 9, 2009 Report Share Posted April 9, 2009 Anyone know if its possible to very slowly melt down plastisol to a certain temp so you dont have to stir it? Any help or ideas would be great! Thanks in advance! Quote Link to comment Share on other sites More sharing options...
bear21211 Posted April 9, 2009 Report Share Posted April 9, 2009 Wildtail In my opinion regardless of how I melted it I would stir it some. If you have glitter or other additives in it you will have to stir it to keep everything suspended. Bear Quote Link to comment Share on other sites More sharing options...
Richard Prager Posted April 9, 2009 Report Share Posted April 9, 2009 (edited) Depending on what plastic and color I'm using, I usually nuke at high (8oz) 2-2:40 add glitter stir and pour. That's if you're not pouring salted sticks Edited April 9, 2009 by 152nd Street Baits Quote Link to comment Share on other sites More sharing options...
longhorn Posted April 10, 2009 Report Share Posted April 10, 2009 I think you always have to stir no matter what temp or what you're using to heat with. Quote Link to comment Share on other sites More sharing options...
gone2long Posted April 10, 2009 Report Share Posted April 10, 2009 I don't think you can get away without stirring it just goes with the territory, anything you add requires stirrring like color, salt, scent or glitter - remember that plastic goes through a gelatin state before it becomes pourable at this point you will always be required to stir.

wildtail97 Posted April 10, 2009 Author Report Share Posted April 10, 2009 Thanks guys. I have something that can keep its heat to +-1 degree. So I thought if you got the perfect heat maybe it wouldnt need constant stirring. How about after it has gone through its gelatin stage, once its heated through, would it stay that way without much stirring? I am planning on making some large batches for the first time. Thanks for the info guys! Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted April 10, 2009 Report Share Posted April 10, 2009 The big problem is that plastic is a poor conductor of heat. Even if you managed to get a good stable heat source, delivering heat evenly all around, without burning the plastic. It would still take a long time before the centre of the plastic volume reached the operating temperature. It would probably take hours just to raise the last 20 degrees. When you heat water in a pan, because the water is thin, it circulates by itself, hot water rising etc. This will not happen with the plastic because of its much thicker consistency, therefore the heat gets isolated around the edges. Constant stirring is required to mix the hot plastic around the heat source with the cooler plastic at the centre. Hope I didn't complicate it too much.

Unfortunately when it loosens up and becomes liquid that is when it requires the most stirring in order to keep your additives suspended.
