Are you heating and stirring in short increments?

Yes no more than a minute at a time

On initial heat I do mine for 1.5 minutes and then 20 second increments.

Before the plastic has a chance to set up after the initial cooking add some stabilizer and stir it in good so its in the plastic before you hit it with heat again. Also, the essential plastic doesn't need to be brought up to 350 or even 340 for the reheat. Try bringing it to 330 using 20 second shots and stirring between hits with the microwave. If the plastic is a lump turn it over between the shots of heat.

If your reheating I use scissors and cut up the plastisol and heat in short bursts . Im reheating 1/2 cup amounts . Cutting it up solved my burning issues. Also adding stabilizer is your friend��

It's the plastisol i had the same problem!! And i use stabilizer and a digital thermometer. Cub48

Something a lot of people over-look when they are working with ANY plastic in a microwave is that when you heat a cup to, say 350 degrees, the plastic will continue to cook to a higher temperature after it has been removed from the microwave. The larger the volume, the higher they after-cooking temp can get and the longer it will continue to cook. Essential is the most forgiving plastic there is when it comes to heat tolerance but if allowed to get too hot it like other plastics will turn. Stabilizer helps buffer any higher heat within reason. Its most likely not the plastic product but rather you need to figure out at what temp to remove the heat source from your plastic so that this after-cooking doesn't over-heat the plastic yet still gets it to conversion on new plastic or at what temp the re-melt has fully melted.

If you are using a microwave, cut a cardboard panel to fit the glass plate inside that your cups set on. These glass trays with a glass cup on it can create some real bad hot spots and the cardboard will help break that possibility up. Even the Pyrex cups can develop hot spots within the glass they are made of and if you are not aware of this you'll be toasting any plastic you put in there.

Most plastic issues are started at the operator.

I have never seen plastic rise in temp once the micro powers down. That would be new to me.
I Had a forum member in the shop just this morning, and we took a 1 1/4 cup of plastic, Initial time of 2:30, then another 30 before we ever stirred it. I then took it to 400 plus, and reheated it to 400 plus and we shot some clear baits.
Hes a essential guy as well. I was just showing off.

What most people don't realize is that heat stabilizer also separates, and you can not mix a box, that has no air pocket in it effectively.
