Shame that hot water can be over 62C...

62 C is about the temeprature of a cup of 'hot' tea.

I've used this.
https://www.rapidonline.com/major-br...-1000g-87-0093

one of a new generation of polymers with all the characteristics of a tough, machinable engineering material, yet fuses and becomes easily mouldable between 30°C and 62°C.

I used a hot air blower to heat it up.

That would appear to be the same stuff.


So I wouldn't use it where the temperature is likely to exceed 30C

Hmmm , usually Polymorph is PCL, Poly Capro Lactone with meting point of 62C

http://remaponline.org.uk/remapedia/...tic-polymorph/

an ebay vendor also offers a low temp version at 42C

Never heard as low as 30C, standard polymorph certainly wont become soft in the hands.

PCL has very high impact strenght and can be used as press tooling.
