Polymer Clay is PVC (polyvinyl chloride) plastic. Similar plastics are frequently used in today's plumbing and water piping. Tiny grains of PVC are mixed with plasticizers and pigments. When the clay is baked at the proper temperature (varying from 212 to 275 degrees Fahrenheit depending upon the make and color), chemical changes occur and the particles fuse into a solid mass without shrinking. If heated again, the clay will soften slightly but not melt (technically it is similar to "thermosetting" plastics, but still has some characteristics of "thermoplastics"). Sand with a light touch with 220 grit and hand finish with higher grit or steel wool. Any scratches or dings can be sanded out and refinished.
