Polyurethane Foam Combined Polyether for Home Appliances

Overview

This combined polyether is a fully formulated polyol component for rigid polyurethane foam used to insulate refrigerators, freezers and similar appliances. It gives fine closed cells, low thermal conductivity and good dimensional stability. 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)
