What is Instamorph?


InstaMorph is an non-toxic, lightweight polyester thermoplastic (woah, that’s a mouthful!). That didn’t help? Ok, how about we tell you some of the properties of InstaMorph that we think you’ll like.

InstaMorph becomes moldable at a relatively low temperature (66°C / 150°F) and solidifies at room temperature. This property alone make it ideal for use for lots of projects and skill levels.

InstaMorph can be remolded again and again simply by reheating it. Make a mistake? No problem! Want to tweak it a bit? Just reheat it!


No messy chemicals here. Just heat InstaMorph in hot water, in the oven, or using heat gun and mold it with your hands (be careful there) or any other tools you might have. See the instructions on using InstaMorph for more detailed information.

The possibilities are endless! InstaMorph even has it’s own specially formulated pigment coloring pellets to help you dye your white InstaMorph into any color you desire. InstaMorph doesn’t stick to much, but will readily bond to some other plastics like ABS (think Lego bricks), acrylic, polycarbonate, polyester, PVC, and vinyl plastics.


InstaMorph is only really limited by your imagination (and what a strong, lightweight plastic would be appropriate for). Still stumped? Check out the dozens of ideas and projects that have users have contributed over the years.
