Products details:
1: Polycaprolactone (PCL) is a biodegradable polyester, This polymer is often used as an additive for resins to improve their processing characteristics and their end use properties. Being compatible with a range of other materials, PCL can be mixed with starch to lower its cost and increase biodegradability or it can be added as a polymeric plasticizer to PVC.
2: Polycaprolactone is also used for splinting, modeling, and as a feedstock for prototyping systems such as a 3D Printer, where it is used for Fused Filament Fabrication (similar to the Stratasys’ Fused Deposition Modeling technique).
3: Polycaprolactone (PCL) is a biodegradable polyester, the most common use is speciality polyurethanes. Polycaprolactones impart good water, oil, solvent and chlorine resistance to the polyurethane produced.
