Polymorph - 50g
Description
Caprolactone Thermoplastic (also commonly called ShapeLock, Friendly Plastic, Instamorph or
Polymorph) is a biodegradable polyester plastic with a low melting point of around 60°C. When solid it
has physical properties of a very tough, nylon-like plastic, but it will melt into a putty-like consistency at
only 60°C. It's specific heat and conductivity are low enough that it is not hard to handle at this
temperature. This makes it ideal for small-scale modeling, part fabrication, repair of plastic objects, and
rapid prototyping where heat resistance is not needed. Though molten caprolactone readily sticks to
many other plastics, if the surface is cooled, the stickiness can be minimized while still leaving the mass
pliable.
Instructions
An easy way that we recommend to shape this Thermoplastic is to heat up some water close to boiling
and toss the granules in. When they become close to clear in color fish them out (NOT WITH YOUR
FINGERS!!!) with a spoon or other such sacrificial item. Wait a little until they cool down a bit and then
start shaping it all with your hands (maybe use some gloves if it's too hot). If you'd like to re-shape it,
just toss the plastic in the water and try again.
Qualities
 Reusable - Just reheat and remold, endlessly recycle-able
 Super Tough, Safe and Non-Toxic
 Machine-able - Easy to saw, drill, tap and mill
