1.1 Polyurethanes
Polyurethanes are the most widely used family of RIM processes.
A urethane is obtained by adding an alcohol to an isocyanate in the following reaction (ionic process):
In practice, the mixtures used, traditionally called components A and B, have the following typical composition:
A:...
