Product Description

InstaMorph is an advanced modeling compound that melts in hot water or air (140 deg F) and solidifies at room temperature. When warm, it acts like clay, but when it cools it resembles a strong plastic. Unlike other products that once they dry they are locked in that shape forever, InstaMorph can be reheated over and over again and re-molded into any number of configurations. When InstaMorph is heated to molding temperature, the pellets turn clear. Once the plastic cools, it returns to its original white color. Use it for making exciting art projects at school or at home. Create props, masks, or other costume pieces for Halloween or theater. Makes excellent brackets, parts, molds, or housings for your next project. Make your own action figures or accessories. Mold around existing handles or grips for an easy ergonomic solution. Make custom cases or stands for the latest electronic gadgets. Ideal for prototypers or makers who want a strong, reusable compound. Mold it with your hands, tools, or press around an object to make a mold. InstaMorph can be painted, machined, carved or attached to other materials. InstaMorph can also be dyed or impregnated with glow in the dark powder for other exciting project possibilities.

5.0 out of 5 stars Strong, easily moldable, has a scent December 27, 2011

By D. Alexander TOP 50 REVIEWER

InstaMorph is an interesting, if slightly finicky accomplice for all sorts of unexpected uses. The container yields BB-sized balls of mostly opaque white plastic, similar to the appearance of the robot skin in I, Robot. When dropped in a bowl of hot water, they'll turn transparent within fifteen seconds and stick together (and to the bowl). You can then drain the water and prod the resulting soft and sticky mass onto any wet surface to mold.

The plastic doesn't retain enough heat to burn. Molding properties are similar to modeling clay. It's very easy to join and smooth edges with your hands or flatten a piece as if it were cookie dough. You can manipulate the shape for about three minutes until it begins to harden. It'll take another ten minutes to reach final hardness, or you can speed the process by putting it in the freezer for a few minutes or running it under cold water.

Beware: InstaMorph gets extremely tacky once it begins to set. If you're molding it on surface that it's not supposed to stick to (e.g., the batteries under the battery door cover I just made) and you make a mistake, don't attempt to pull it off while it's still partially pliable. You'll just leave a plastic residue that'll be almost impossible to remove later. If you wait until it hardens, it'll come off in one piece and you can start again.

When totally hard, strength is similar to standard, non-specialized toy plastic. It is not at all brittle and will bend under load. While you can cut very thin (under 1/16") sections with scissors, it's almost impossible to tear at any thickness. I created a simple tube about 1" in diameter and 1/8" thick and was able to stand on it with minimal deflection.

You can't weaken the material with handling.... Even concerted rubbing doesn't put enough heat into it, though a fingernail can scratch it. If desired, the final product can be painted or epoxied to other surfaces. It's best not to store remnant pieces in thick shapes because they'll take much longer to heat through. Just make a thin pancake and cut it later with a pair of scissors.

The only negative of this product is that it has a noticeable, albeit subtle, scent. Handling will convey this scent to your fingers. I wouldn't go so far as to call it a residue, but any smell at all implies at least some material transfer. Given that the FDA approves medical grades for use in the human body, I'm not terribly concerned about health consequences, though I probably wouldn't attempt to microwave this product. Read more ›

4.0 out of 5 stars Great for making moldable plastic parts. April 11, 2011

I bought this to make a plastic windscreen for a digital voice recorder (DVR) I sometimes use while riding a bicycle. I found it very easy to draw on a piece of sheet metal the outline of a flat sheet shape that I would eventually bend to fit my DVR. I then placed the pellets on the sheet metal, to fill the outline, and placed the sheet metal over the top of a pot of boiling water. In a few minutes the pellets became clear, indicating that they are soft enough to mold. I could then add pellets where I had any areas not well filled by the initial bunch of pellets.

Once the flat shape was done, I put the sheet metal and InstaMorph shape into the freezer. A few minutes later I found that the InstaMorph released easily from the sheet metal. Next I heated a measuring cup with water to a temperature of 150F. I dipped the InstaMorph sheet into the hot water, waited for it to turn clear, and then wrapped it around the DVR (covered in plastic wrap, to avoid water damage and possible adherence by the InstaMorph). This all worked very easily.

I later warmed the InstaMorph windshield to flex it enough to have the desired friction fit to the DVR. It has reduced the effect of wind noise on the voice-activated microphone of the DVR. The windshield in plenty sturdy, too.

I recommend this product for such applications and look forward to other needs I may have for it in the future. When melted it is like modeling clay that will make a reasonably strong plastic part when it cools.

5.0 out of 5 stars Limited by creativity, only May 22, 2011

By Tugboat

I keep coming up with new uses for this stuff. It's incredibly stiff and strong for it's weight, and the complexity of shapes you can make is amazing if you have the patience and a few techniques. I use it in my workshop all the time for spacers and brackets to hang things, and I'm making a low-output heater unit now and this stuff may even be up to the task for that (might have to find something a little higher temp. But I'm re-ordering because my friends daughter came over the other day and we made crowns and such out of it and I sent them home with the rest of my container.

I wish I'd had this stuff as a kid.

I purchased this for the Imako Cosmetic Teeth Cover-up, but since receiving, I have been able to use it to temporarily fix a water main leak to my house and replace the broken plastic on my son's SUV sun visor to repair it. It has worked for everything I have tried it on! Amazing invention.

4.0 out of 5 stars Pretty cool for making quik plastic castings, for room temperature use. August 24, 2012

I ordered a small amount to try it out, and will definitely be ordering more. You can use this stuff to make a mold for other items, or use it as the finished product, assuming that product never gets too hot. At room temperature it's machinable, drill-able, it will take a screw, you can glue it, you can use your standard woodworking tools on it, what ever. I first tried to heat it in a double boiler, but heat transfer to the pellets in the center was going to take forever, so I just threw them in the boiling water, and had no problems. The stuff seems to self homogenize, and gets rid of air bubbles and water bubbles easily by itself. All in all, I'm impressed.
