Ever tried to melt something plastic at home? It takes a fair amount of work. Not this new plastic product, though — it’ll go goopy just from taking a brief bath in hot water. A Japanese plastics company called Polysis is marketing a new product they call Haplafreely. It’s available as rigid sheets or as thin film on a roll, and it’s noteworthy for its ability to become malleable with a minimal amount of heat applied.
At 140 degrees Fahrenheit (60 degrees Celsius), Haplafreely becomes as squishy and moldable as clay. It doesn’t start firming up until its temperature drops to around 104 degrees Fahrenheit (40 degrees Celsius). At room temperature, it regains its original hardness. It’s very strong, too: Haplafreely has a tensile strength about three times that of ordinary rubber, according to Polysis.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
