Polyurethane Foam Chemical Formula

Polyurethane Foam Chemical Formula. The stoichiometry of the starting materials must be carefully controlled as excess isocyanate can trimerise, leading to the formation of rigid polyisocya… A polyurethane foam made from such a formulation has a density of from 50 to 110 kilograms per cubic meter (kg/m 3) as determined by the astm d 3574 method.
