Polymorph Mouldable Plastic Pellets 500g with 4 Free Colouring Sachets in Resealable Bag Made in UK, Red-Black-Yellow-Blue

For many people this will be one of those products you don't think you have a use for, until you get some... Ok so I am a bit of an unusual case, in that I am pretty much *always* making, fixing or modifying something - so I bought some of this knowing it would come in handy at some point. I wasn't wrong. So far I have used this stuff to take impressions of various things to create moulds, formed handles for tools which (apart from the missing handles) were otherwise fine, and created temporary 'scaffolds' as a way of forming close-fitting custom car parts. It is super easy to use - just dunk the pellets in hot water, wait for them to become clear, then squish the resulting goo into shape! It is very firm to handle, and of course the firmness increases as the plastic cools so it is best to work quickly (you've got a few minutes at ambient temperatures). Possibly the best thing about this plastic, particularly for those of you who will be making moulds, is that you can re-melt and mould as many times as you like! Brilliant! Once it hardens you can cut, file, sand and paint it to create permanent pieces...just don't make anything that's going to get hot or your masterpiece will turn into a sad little puddle. All in all, great stuff with loads of applications and the remouldability (that's a word, why shouldn't it be?) makes it great value for money. Get some!

This stuff is fantastic ....i love it , and so do the kids it can be re used over and over again .Polymorph has unlimited uses, from prototyping new products, creating gadgets and toys to forming replacement parts and general DIY repairs. This is the strongest Polymorph available on the market and its immense strength makes its DIY possibilities huge. Adding colour to Polymorph or painting finished products allows an even more impressive range of shapes and ideas to be created.. Polymorph is completely re-usable, allowing it to become flexible again once heated above 62°C, at which point it will revert back to a mouldable condition, allowing it to be re-formed into a different shape or product. Polymorph is completely biodegradable in soil conditions and is 100% non-toxic. It can be coloured using our powder additives or painted when hardIned. I have even looked at you tube clips of people making temporary teeth out of the stuff, and fake fingers for Halloween . I have realised though that if you use a lot of it and it sets into a large clump it is much more difficult to re melt , so i advise using smaller amounts if you want to re work the stuff.

Very good product, the beads are workable almost instantly when poured into boiling water making it very quick to get started. Models are very strong, really surprisingly hard to brake. My firs thought after creating a quick test model was to try and snap/bend/warp and generally try to destroy the small figure i had created to no great success. Bending the plastic resulting in it bending back to almost its exact original form, snapping just did not happen regardless of how hard I tried. A really great product for both children and for university/college product design prototypes. The reason I took one star away is that reheating a model to reuse to takes far longer than expected, although the beads can be heated in seconds in boiling water, sculpted solid models will take around 15 minutes to become malleable again. I even had to change the water for fresh hot water from the kettle. The models I created were probably roughly the same size as an average computer mouse and required 15-20 minutes in boiling water to be sculpted. This in no way made me regret my purchase, or would put me off buying more in the future, but the time to remold models was far longer than I expected. Regardless I would highly recommend this product, but would advise patience when looking to reuse the plastic from models

I've added a video, I apologise if the playback quality is really bad on Amazon, I don't know why that happens. I don't think I'm allowed to link to external videos here. PROS: - Super strong. I tried ripping a super thin (1mm x 5mm) flat ring after it had cooled and it was really difficult, even with pliers. In larger pieces I would consider it basically "indestructible" but obviously it would depend what you're trying to do with it. - Easy to shape to almost anything. - No odour. - When cooled it has a nice fairly smooth texture. HEAT: It melts in water that is 50c, but then cooling time is a bit too quick. 70c water was much better, melts faster and malleable for a longer time. For my hands 70c does not cause burns if I touch it for a short amount of time, but obviously you should be very careful when working with hot water, always monitor the temperature with a reliable thermometer and never stick your hand into the water. CONS: - Takes a bit of practice to shape it in time before it cools, especially when working with very small pieces, as they cool down much faster. Larger pieces are much easier and have a bit more work time. - I tried to mix a tiny amount of white and colour pellets, in my experience it was nearly impossible. Even with the small amount I was using (probably 10 white and 3 black), i found they just didn't mix, they just cool down too fast. I warmed the same piece up about 5 times and even tried cutting it up and squishing it with pliers and I tried mixing them while it was still inside warm water, etc. Nothing helped, the colour just mostly remained in separate areas. Maybe I was doing something wrong. I guess maybe you can just use the coloured pellets as they are, but then you wouldn't have a very large amount. CONCLUSION: Very pleased. Well worth the £14 or so for 500g. Great addition to a maker's tool kit, but I doubt I would recommend this as a thing for the average household.
