Product Description
Easy to melt and shape into your creation
Polly Plastics Moldable Plastic is perfect for making plastic parts without injection molds or 2-part epoxy systems. Just heat the pellets in hot water above 150 degrees F for 2-3 minutes until they turn from white to clear. Remove them from the water and you can mold them into any shape you desire. Upon cooling, they will be strong and permanent. If you change your mind, you can reheat and modify until you get it right. Since this plastic is so strong, you can drill it, sand it, varnish it or superglue it to something else. Safe to use.
Polly Plastics Moldable Plastic is great for crafts, art projects, home repair, model making, toys, cosplay costumes/masks and prototyping. Use it make custom parts, handles, grips, hooks, brackets and cases. We’ve included an Idea & Instruction booklet to help you get started and inspire your creativity.
Add color by melting a few Polly Plastics Color Pellets (sold separately) along with the moldable pellets. Or you can add powder paint or alcohol dye (available at craft stores) to the molten plastic. Alternatively, apply acrylic paints or special spray paints for plastics after your part has cooled. Add a polyurethane top coat to lock in color. You can even color the surface with permanent markers.

I used these product in place of rice that I had used in a crafting class to make gnomes. The rice I realized would attract rodents so I wanted it gone. This works perfectly! I didn’t obviously try melting or molding but now I know it’s available. It was a bit pricey but since it kept me from tossing a craft that I had done with my granddaughter it was worth it! The pellets are tiny smaller than rice, if that matters to you.

Plastic once formed on ball vise and heated up a bit and piece to be engraved is pushed into plastic - holds thin pieces very well. Much better than clay and can be reheated to release piece and then used again.

Recovering from hand surgery. Zero ability to grasp or make a fist. These pellets are similar to those used in my OT's office for therapeutic exercises and are excellent for this purpose. So glad to have found them! Thank you!

This stuff is hard to melt down. If you go to hot and burn it the fumes will make you very very sick. Known as polymer flu.Symptoms are identical to the flu but worse in my opinion. Stay safe out there.

This stuff is neat. Very easy to use. I recommend an electric kettle and starting with really hot water and letting it cool to a handleable temperature after becoming translucent and removing from the water. Although I did read the instructions, without thinking I donned my vinyl food service gloves. I barely poked the softened material before realizing that was a bad idea. It would have stuck to it. So I quickly removed them and carried on.Now, the reason I bought these thermoplastic pellets (in addition to just being the crafty sort of individual) is for an off label use. The instructions clearly state that it is not for internal use and I accept any liability in my usage of it. With that disclaimer in mind, it does work for making a mold of your teeth. It doesn't taste bad or like anything actually while molding it to teeth. I can imagine that it could very well stick pretty well to teeth if you swished cold water around and it really set up, but that's not what I'm trying to do with it. I love that you can just keep warming it back up to reuse it. I can see using it for many different prototypes and quick fixes where you need to replace a lost piece. Done with one modeled item? Make a mistake? Remelt it and make it into something else. It is fairly flexible when cooled, but solid, not brittle. I tested it by bending several times and it didn't break. Excess material needed to be cut away. They say it can be sanded but I haven't tested that yet. It is white in color but is not fully opaque. I can't wait to try coloring it! And now that I have a better idea of its material qualities, I can't wait to see what uses I will find for it. The 7oz I purchased will go a long way but I can definitely see myself reordering!

...of a dumb person. That dumb person is me.Once upon a time, a complete idiot put a non-dishwasher-safe water bottle into the dishwasher and washed it. The bottle emerged warped, and thankfully the lid still screwed on so it was usable, but the bottom had shrunk so the plastic in the center stuck out, making it unable to stand upright. The child who owned the water bottle was none too pleased. That left the dumb person with a conundrum. How to fix the water bottle?Then, a flash of inspiration. The dumb person sought out and purchased a bag of Polly Plastics pellets, having used a similar plastic in the past for making silly things like props and monster teeth for LARPing in their youth. In the old days, this friendly plastic came in strips and was a hassle to heat and shape. The Polly Plastics pellets, however, were very easy to use - with only boiled water from a kettle, the dumb person was able to put some pellets into a coffee mug that the water bottle fit snugly into, heat them with the water, then pour off the water and jam the water bottle into the mug. After twisting it to and fro a few times, the dumb person easily extracted the water bottle and was delighted to find that it now sported a crude-but-functional flat bottom.The child was pleased, and the dumb person was now slightly less dumb, and could almost be considered innovative. Please note that the water bottle certainly now cannot go into the dishwasher as melting Polly Plastics pellets would surely wreak havoc, but fortunately this water bottle is very distinctive and the lesson has certainly been learned.Since repairing the water bottle the child has absconded with the bag of Polly Plastics pellets, as they are working on cosplay and were very keen to use it to make teeth and claws and all sorts of thingamajigs. Thank you, Polly Plastics, as your pellets have positively saved the day.

I'm going to need to order a couple more packages before I can truly say that I have enough to make what I want, but damn, this stuff really works. The instructions say that it'll be ready to mold in a couple of minutes, but it only took mine an absolute maximum of 30 seconds!

Well I like how easy it is to shape to my needs. Sucker is hot AF tho! Be careful when handling it when out of the water. I let the water drip off for about 3 seconds with 2 gentle shakes. What I didnt like was, it stuck to the bottom of my pot and my tongs I used. I'm not sure of it's the type if pot I have but I let it cool down a bit and I was able to just wipe the pot clean. My tongs however I had to pick a bit to clean it off. I am using this product to to refill my polymer 80% lower I messed up on while milling. I'll try to give an update when I remill the lower. Hope it works. But so far excellent product.
