- Product
- Polyurethane Foam Combined Polyether for Pipes
Overview
This combined polyether is a fully formulated polyol component for rigid polyurethane foam used to insulate pre-insulated pipes. It offers good flow in long pipe sections 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)
