Esterification
Esterification is the process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water. This reaction occurs at high temperature and the presence of titanate base catalyst in the discontinuous esterification reactor.

Pre-polymerization
Prepolymers are frequently used in injectable two-component systems to improve handling properties or reduce toxicity. Isocyanate-terminated prepolymers are prepared by reacting an excess of a polyisocyanate with a polyol at 60–90 °C in the presence of a urethane catalyst, such as dibutyltin dilaurate. By varying the molar ratio of polyisocyanate:polyol, prepolymers with targeted NCO content and average molecular weight can be prepared. The NCO content of prepolymers typically ranges from 5 to 25 wt%, while less viscous quasiprepolymers typically have NCO content exceeding 25%

Polyurethane system
Polyurethane systems consist of two components, one of which is a mixture of polyols with additives and the other a diisocyanate. When mixed homogeneously, they react forming polyurethane. The first of the components of the system is the mixture of polyols with reactive -OH groups, containing catalysts, flame retardants, expansive agents and foam stabilizing agents. The second component of the polyurethane system is the Isocyanate, a bond of one or several NCO groups. The most common would be the aromatic types (MDI, TDI, PMDI), but there are also aliphatic types.
