Voici le plastique polymorphe !!
"PCL also has many applications in the hobbyist market (sold under various tradenames, such as "InstaMorph", "Plasty Craft", "Friendly Plastic", "ShapeLock", "PolyMorph", "Plastimake", "Protoplast", "Plaast" etc.). It has physical properties of a very tough, nylon-like plastic that softens to a putty-like consistency at only 60 °C, easily achieved by immersing in hot water. PCL's specific heat and conductivity are low enough that it is not hard to handle by hand at this temperature."

Pinaise ça a l'air bien ça..seulement je ne trouve pas le vrai non de ce plastique.
thermo plastique polymorphe, friendly-plastique...mais je ne connais toujours pas le vrai nom.
Je sais juste qu'il fond à 60°C et que l'ont peut le remodeler à l'infini.

polymorph pellet, polymorph plastic ça semble bien marcher.
