POFI-Engineering: Nucleation unit for continuous lines

The production of rigid polyurethane foam requires two main liquid components, a polyisocyanate and a polymix (Polyol and a blowing agent). The blowing agent is usually added to the polyol with further auxiliary components such as activators (reaction accelerators), foam stabilizers and flame retardants.
