What is polymer clay made of?
Polymer clay is made from PVC powder, plasticizers, binders and fillers, lubricant, and pigments. As the temperature increases during curing, the powdered PVC softens in the plasticizer and the particles begin to absorb the plasticizer. Optimally, the particles will eventually fully fuse together and form a solid mass of plastic. If polymer clay is underbaked, the fusion will not be complete and the resulting clay mass will be weak. Underbaked clay is not only less flexible, it is susceptible to breaking and crumbling. Underbaked polymer clay can also have excess free plasticizer that can lead to cure inhibition in paints and glues, causing them to remain soft and/or sticky.
How hot does polymer clay burn?
Let me be very clear. Polymer clay does not burn unless it reaches temperatures near 350°F (176°C). (Fimo is a bit more sensitive.)

When the oven’s heating element cycles on and off, the heat radiating from it can be tremendous. If your project is close to the element, your thermometer could be reading the correct temperature but your project could still bubble and blacken. If you have burned polymer clay, you need to address your oven, not your baking times.
