ملف:Polycaprolactone close.jpg

• Polycaprolactone from Dow Chemical in microwave oven. It is used in prototyping, dental impressions, absorbable sutures, and form fitting cutlery handles for disabled people, and melts at 136 degrees F.
• A "cool' effect is that they melt at low temperatures, moving from hard white plastic to transparent silly putty. The temperature is so low that you can stretch and mold it by hand into any shape and it becomes hard solid plastic when it cools.
