How Polyurethane is Produced

Polyurethane Foams are made from poly-alcohols and disocyanates.

How Polyurethane is produced

Polyurethane is produced by combining a diisocyanate and a dioland two monomers through a chemical reaction.

The chemical reaction point is the  "urethane" which is the ester from a carbamic

R' - NH - C - OR 

The polyurethane is the reputition of this group in a micro-molecular chain and may be obtained by the polymerization reaction of a polyalchol with a poly-isocyanate

n HO-R-OH + n OCN - R' - NCO - - (R-O-C- R'-NH-C-O) n - 

This produces a material whose variations can be stretched, smashed or scratched and remain fully indestructible. Depending on the type of diisocyanates and diol or polyol constituents used will result in the polyurethane taking a liquid, foam or solid form each with advantages and limitations.
