How can you making polyol of mdi foam?

Answer 1

To make a polyol for MDI (methylene diphenyl diisocyanate) foam, you typically start by reacting a polyol with additives like surfactants, blowing agents, and catalysts. The polyol can be derived from various sources, including petrochemical feedstocks or bio-based materials. The mixture is then blended and processed to achieve the desired viscosity and properties, which will later react with MDI to form the foam. The resulting polyol must be carefully formulated to ensure optimal performance in the final foam product.
