Polyurethane Foam Combined Polyether for Sandwich Panels

Overview

This combined polyether is a fully formulated polyol component for rigid polyurethane foam used in continuous or discontinuous production of sandwich panels with metal facings. It gives good flow, adhesion and low thermal conductivity. It contains polyether polyols together with catalysts, foam stabilizers and blowing agents, and is foamed by mixing with polymeric MDI at the ratio given in the technical data sheet.

Also known as

Combined polyether; Polyol premix (polyol side of a two-component rigid foam system)
