STEPANPOL PS-2352 is a modified aromatic polyester polyol designed for use in rigid foam applications. Compared to other aromatic polyester polyols, Stepanpol PS-2352 provides improved compatibility with a variety of blowing agents, allowing for increased processing latitude and improved strength and insulation properties. Additional applications include polyurethane coatings and encapsulants.

Applications include rigid polyisocyanurate boardstock blown with HCFC-141b/water (with or without R-22), or blown with hydrocarbons and modifier copolyol for polyurethane foams. This product can be used for production of HCFC-141b-blown and HCFC-141b/water-blown polyisocyanurate boardstock meeting the requirements for roofing and sheathing. Low hydroxyl number for economical isocyanate usage. High aromatic content.
