Polycaprolactone (PCL) is a biodegradable polyester with a low melting point of around 60°C and a [[glass transition temperah starch to lower its cost and increase biodegradability or it can be added as a polymeric plasticizer to PVC.
Polycaprolactone is also used for splinting, modelling, and as a feedstock for prototype Fused Deposition Modeling systems such as RepRap.
