Polymorph pellets are also known as polycaprolactone (PCL). These small, milky white, bead-like pellets are more than what meets the eye. For when submerged into boiling water, the granules soften and fuse together forming a mass of clear material with endless possibilities and applications.


Polycaprolactone (PCL) is a biodegradable, thermoplastic. Thermoplastics are polymers that become pliable above a specific temperature – in the case of PLC, the relatively low melting point of 60°C. The polymer chains that form the backbone of PLC are linked by very weak bonds; bonds that rapidly weaken further with increased temperature, eventually yielding a viscous liquid from what was once a solid-state polymer. The amorphous nature of its polymer chains means the properties of PCL can change drastically without its structure becoming brittle or damaged. From solid to liquid and back again, PCL can be continuously shaped and reshaped to your heart’s content.  


The biocompatibility and ideal degradation rate when placed in physiological conditions has made PCL an ideal candidate for use in an array of medical applications including: long term implantable devices, controlled release drug delivery, suturing and scaffolding. In addition to its medical applications, PCL has many uses within manufacturing and prototyping processes. When in a solid state, PCL has the physical properties of a very tough, nylon-like plastic. Its seemingly effortless transition from tough plastic to mouldable putty makes PCL ideal for small-scale modelling, repair, rapid prototyping and as feedstock for FDM 3D printing.
