XF-2412
XF-2412 is a modified aromatic polyester polyol manufactured by Stepan Company, primarily used as a key raw material in rigid polyurethane and polyisocyanurate foam formulations. It is engineered to deliver enhanced performance characteristics in insulation and rigid foam applications compared with many standard aromatic polyester polyols.
Chemical Type: Modified aromatic polyester polyol.
Functionality: Polyester polyol (reactive component used with isocyanates to form polyurethane/PIR).
Liquid at Room Temperature: Yes.
| Property | Typical Value |
|---|---|
| Hydroxyl Value | ~240 mg KOH/g (indicates average functionality/reactivity) |
| Specific Gravity (25 °C) | ~1.24 |
| Viscosity (25 °C) | ~2,000–4,500 cP (moderate viscosity) |
| Acid Value | ~2 mg KOH/g (low acidity, helps consistent polyurethanes) |
| Flash Point | >94 °C |
| Form | Liquid |
XF-2412 is predominantly used as a component (polyol side) in the manufacture of rigid polyurethane (PUR) and polyisocyanurate (PIR) foams, where it contributes to:
Boardstock Insulation Panels (commercial, residential).
Pour-In-Place and One-Component Foams.
Rigid Bunstock Insulation.
Flexible-Faced Boardstock.
Tooling Foams.
The aromatic polyester backbone provides rigidity and heat resistance to the resulting polymer, making it suitable for structural foam applications.
Improved Flammability Performance & Stability: Compared with certain other aromatic polyester polyols, XF-2412 exhibits better fire performance attributes and B-side emulsion stability in foam systems.
Low Color & Consistency: Its raw material purity contributes to consistent processing and product quality.
Shelf Life: Typically has a 24-month retest period in sealed, unopened containers. Recommended storage is 15–35 °C to maintain quality.
According to the safety data sheet, XF-2412 is not classified as hazardous under typical criteria (though appropriate industrial hygiene practices should always be followed).
Parameters
XF-2412 is a high-performance aromatic polyester polyol widely used in rigid foam and insulation polymer systems to improve heat resistance, stability, and overall foam performance in industrial polyurethane/PIR applications.
| Characteristic | Value |
| Color | Colorless or pale yellow |
| Hydroxylvalue(mgKOH/g) | 260±10 |
| Acidity(mgKOH/g) | ≤1.5 |
| Moisture% | ≤0.10 |
| Viscosity(25℃,cps) | 8000±1500 |
