Answer 2

plastics are made from 2 chemicals Polyol and Isocyanate combined they cause a reaction and harden. depending on the density desired the combination is adjusted, usually your polyol is the softer of the 2 compounds so less iso= softer plastics more iso and less poly creates harder plastics.
