Polly Plastics Moldable Plastic is perfect for making plastic parts without injection molds or 2-part epoxy systems. Just heat the pellets in hot water above 150 degrees F for 2-3 minutes. Remove them from the water and you can mold them into any shape you desire. Upon cooling, they will be strong and permanent. If you change your mind, you can reheat and modify until you get it right. Since this plastic is so strong, you can drill it, sand it, varnish it or superglue it to something else.
