POLYOL - ISOCYANATE: POLYURETHANE CHEMICAL. Polyol is one of the two main components used to produce polyurethane foam. It is not a single pure substance—it’s usually a blend of several ingredients designed for specific foam types. In simple terms: Polyol is the “soft part” of polyurethane foam. Key features: Usually a thick liquid Can be polyether polyol or polyester polyol Determines: Flexibility (soft foam like mattress) Rigidity (hard foam like insulation) Isocyanate is a highly reactive chemical that contains –NCO groups. In simple terms: Isocyanate is the “hard/reactive part” that makes everything bond together. Common types: MDI (Methylene Diphenyl Diisocyanate) → used for rigid foam TDI (Toluene Diisocyanate) → used for flexible foam (e.g., cushions
