Combined polyether for spraying

Combined polyether for spraying is a key raw material used in polyurethane spray foam insulation systems. It is mainly composed of polyether polyols, which are polyol compounds containing ether bonds (-O-), the hydroxyl group (-OH) in its molecular structure can react with isocyanates. In addition, combined polyethers also contain catalysts, such as tertiary amine catalysts, which regulate the speed of foaming and gelling reactions. Blowing agents are also an important component, common physical blowing agents are hydrofluorocarbons (HFCs), etc., but with the improvement of environmental protection requirements, some new environmentally friendly blowing agents are gradually being used. Foam stabilizer can make the foam more uniform and stable in the formation process, and prevent the collapse and co-foaming of the foam.
