About this item

  • LIGHTWEIGHT & STRONG: InstaMorph is a lightweight polyester thermoplastic which acts like clay when warm, but when it cools, it’s a strong plastic. Mold it with your hands, tools, or press around an object to make a mold. It can be painted, machined, carved or attached to other materials.
  • REUSABLE PLASTIC: About 1 ounce of InstaMorph will form a one-inch cube of moldable plastic. It can be remolded again and again simply by reheating it. Make a mistake? Just reheat it!
  • GET CREATIVE: InstaMorph is ideal for makers, hobbyists, artists, fixers, cosplayers, tinkers, or anyone else that needs a custom part made out of plastic. You can create everything from masks, costume pieces, brackets, molds, toys, handles, grips or replacement parts.
  • EASY TO USE: Simply heat InstaMorph thermoplastic in hot water (150°F), in the oven, or using a heat gun and mold it with your hands, tools, or shape it around an object to create a plastic mold within minutes. Once the beads are clear, let the fun begin.
  • INSTAMORPH PIGMENT PACK: You can dye classic InstaMorph into any color you desire by by purchasing our color pack. They come in blue, red, yellow, and black.

"...Also, it cools rapidly, so you can use boiling water, fish it out with a spoon, wait about 30 seconds and start molding it in, then put the denture..." Read more

109 customers mention36 positive73 negative

"...No issues. If you have missing teeth. Get this. Yes it gets hard pretty fast. But not THAT fast. Just heat it back up. I just keep reheating mine...." Read more

"...first and only attempt so far at making myself my new tooth and it hasn't budged yet...." Read more

"...The plastic itself does get hard, like really hard after you've molded it into whatever, so this could be used as a replacement to whatever it is you..." Read more

Great for making retainers
I was clued into this product by a Youtube video demonstrating how to make a retainer out of this stuff. Unlike most people looking to make retainers, I still have my original upper and lower Hawley retainers from 20+ years ago, and yes I still wear them every night, and yes my teeth still look great!! I've had new dentists stare at me like I'm a rainbow-colored unicorn sitting in their chair.I was interested in getting a second set of retainers for short-term travel purposes, so I wouldn't have to move my original retainers from container to container, possibly forget to pack them, and there's always the risk losing them. My original orthodontist has retired by now, so I looked into how much it would cost to get a second set from an unaffiliated dentist/orthodontist and found I was not willing to shell out hundreds of dollars for something that would mostly sit idle except for a couple days' worth of travel a year.Enter this InstaMorph plastic. I wasn't sure whether to get the 3oz or 6oz size, and eventually chose the smaller one. Turns out 3 ounces was more than enough. I made my retainers quite thin for comfort, but I also have tons of beads left, even after accidentally wasting the first small spoonful by putting it into water that wasn't hot enough. You'll know the water isn't hot enough if the beads don't turn from opaque white to clear. If they stay opaque, they don't bunch up together, and instead stay loose and unusable. What I should have done at that point was add more, hotter water to get them to turn clear and bunch up together, but I wasn't thinking at the time and just dumped the whole mixture into the trash, Luckily, I had plenty of the stuff left to try again.My next attempt was successful, as with hot enough water, the beads turned clear and bunched up together such that I could scoop them out of the water in one piece and start to mold them. I basically rolled them into a log shape, then used a small plastic rolling pin to flatten the log out into a really thin rectangular piece, and then tried to mold the piece to my teeth. This took a long time and a ton of trial and error, and I was constantly refilling hot water and re-dunking the piece to get it more pliable again so I could roll it out even thinner, shape it to my teeth better, or cut off excess with scissors (it's way easier to get smooth cuts when semi-pliable than when hardened). Creating the upper retainer was a huge chore. The lower retainer went way quicker and easier, but I'm not sure if that's because I created the upper one first, because I wasn't fighting gravity, or some combination of both.In the end, I now have an extra set of retainers for those rare travel days, it only cost me about $10, and despite how long and how much effort it took, I am very pleased with how they turned out. There is some pliability in the plastic since I made them so thin, but that makes them more comfortable and I can tell they are plenty rigid enough still to hold my teeth in place overnight. Very happy with my purchase, and wondering what other nifty uses I can put the remaining beads to.
