About Our Products

　　The polyester polyols belongs to the fragrant kind of polyester polyols, by PA, DEG, Hexylene glycol and NPG and so on responds after the catalytic esterification but becomes. Mainly applies in thermal insulation, construction and refrigeration industries, such as Pipe Insulation, Water Heaters, Appliances, Vending Machines, Aerospace and Spray Foam etc. Performance characteristics of Our Products are following:

　    •  Stable properties, white color and very fine foam
　　•  Good tenacity and good sound insulation
　　•  Good activeness in reaction and good adhesiveness
　　•  Good in heat, cold and oil standing
　　•  Good in flame retarding
　　•  Able to reduce obviously thermal conductivities

STEPANPOL PS-3152 ：

is a diethylene glycol-phthalic anhydride-based polyester polyol.This product can be used in rigid isocyanurate boardstocks and low density, pour, spray, high density and packaging polyurethane foams. It can also be used in formulating urethane coatings, adhesives, sealants, and elastomers

STEPANPOL PS-2412 ：

is a modified phthalic anhydride-based aromatic polyester polyol.Rigid polyisocyanurate boardstock blown with HCFC-141b/water (with or without R-22), or blownwith hydrocarbons; extender for polyurethane foams.This product can be used for production of polyis ocyanurate board stock meeting industry requirements for commercial roofing and residential sheathing applications. Its high aromatic content contributes to polymer rigidity and heat resistance. As a result of its pure raw material base, this polyol offers low color, low viscosity, and consistent performance.
