Polycaprolactone (PCL) - A polymer with a very low melting point
This polymer has a melting point of only 60°C, which means it can be shaped by hand after a few minutes in hot water. PCL can be reheated and reshaped again and again. It feels like nylon when hardened.
Polycaprolactone (PCL) is originally an industrial polymer with applications in, for example, hot-melt glue and laminating pouches. It is also used for model making and prototyping. It can be used to make moulds for reproduction. It is also used for jewelry making under the brand name Friendly Plastic.
PCL is non-hazardous and biodegradable; it can be coloured with fruit colours. Typical modulus of elasticity is ~440 MPa and tensile strength is ~16 MPa. PCL is resistant to water, oil, solvent, and chlorine. Polycaprolactone is also sold under the names Shapelock (US), Polymorph (UK), Instamorph, PlastiMake (AUS) and Friendly Plastic.
The material is delivered as granules that can be easily melted in hot water and shaped. We can sell any quantity, so please contact us if you need larger quantities or have questions.
All samples come with a laminated information card.
We are now also stocking polycaprolactone in the form of mesh and sheets. See the products here.
A new variant:
We also supply a new variant of polycaprolactone that melts at just 42°C. You have longer time to shape this material before it hardens and it is not as hot to touch when melted. Click here to learn more about this material.
