PU(Polyurethane)

A Class of very versatile polymers that are made into flexible and rigid foams, fibers, elastomers, surface coatings, surface coatings, and adhesives. They are produced by reaction a diisocyanate (a chemical with two functional groups of the type – NCO) with a diol (a chemical with two functional groups of the type – OH)

PUD(Polyurethane Dispersion)

– Assembly of polyurethane particles with hydrophilic (tend to associate with water molecules) groups in the main chain of molecules in water.
