Coolmorph Thermoplastic

Coolmorph™ is a new thermoplastic polymer which melts at 42°C and consists of small off-white plastic granules. By heating these granules in warm water (usually form a hot tap or similar) the user can easily melt the pellets to form a transparent flexible material. Once melted the pellets fuse together, become transparent and soften, allowing the user to form the plastic by hand into unique shapes, easily and at a comfortable temperature. Coolmorph™ has unlimited uses, from prototyping new products, creating gadgets and toys to replacement parts and general DIY repairs. Coolmorph™ appeals to almost everyone and it's low melting point makes it easier and safer to use than ever before, allowing your imagination to create new and impressive products and gadgets, or for simply messing around with. Coolmorph™ can be used by kids from the age of 6yrs+ if supervised by an adult. Adding colour to Coolmorph™ or painting finished products allows an even more impressive range of shapes and ideas to be created.
