HOW ARE SQUISHES MADE?
Well there are two ingredients that you need to make a squishy. These are made out of PU which stands for polyurethane. PU comes in 2 varieties Gummy Cast Soft and Gummy Cast Hard. They are both made from urethane resin.
Polyurethane was first researched in Germany by Friedrich Bayer in 1937.
FACTS ABOUT POLYURETHANE:
1.6cm-thick polyurethane insulation has the same insulation efficiency as a 1.34m-thick concrete wall!
the first polyurethane surfboard was made and used in the 1950s.
in 1973, roller skates were improved and popularised by the introduction
of thermoplastic polyurethane (TPU) wheels and, later, TPU boots. Today
they are known as Rollerblade's.
