XF-2402N
XF-2402N is a premium-grade aromatic polyester polyol engineered specifically for demanding rigid foam applications. Formulated as a transparent, highly consistent viscous liquid, it serves as the foundational reactive component for rigid polyurethane (PUR) and polyisocyanurate (PIR) panel systems. This formulation is meticulously designed to support both continuous and discontinuous insulated panel manufacturing lines, delivering exceptional structural integrity for cold room panels, architectural wall panels, roofing insulation, and composite sandwich panels.
Manufactured under strict ISO 9001, ISO 14001, and ISO 45001 certified management systems, every single batch undergoes rigorous 100% factory testing before dispatch. This ensures that critical chemical properties remain highly consistent, preventing unexpected variations during your foam pouring or spraying processes. The distinct aromatic ring structure inherently boosts the char-forming capability of the foam, providing a reliable foundation for meeting stringent international fire safety standards while maintaining excellent thermal insulation.
The versatility of XF-2402N allows it to be deployed across a wide spectrum of thermal management and structural insulation projects. It has been successfully utilized and validated in major international benchmark projects, including large-scale European cold storage facilities and extensive Indian pipeline insulation networks, demonstrating exceptional weather resistance and structural support.
Proven in extreme low-temperature environments, the resulting foam maintains core stability, prevents thermal bridging, and significantly reduces energy consumption for industrial freezers.
Delivers the precise cellular structure required for commercial refrigeration units, ensuring long-term thermal efficiency without degradation over time.
Provides excellent compressive strength to withstand external environmental loads, wind pressure, and foot traffic during the installation of architectural envelopes.
Optimized for high-speed double-belt lamination, ensuring rapid curing, even distribution, and smooth flow without clogging mixing heads.
Offers excellent flowability to completely fill complex mold cavities before the foam sets, eliminating internal voids and ensuring uniform density.
Formulators and production managers value this aromatic polyester polyol for its exceptional operational reliability and chemical synergy. Backed by our dedicated product application center and senior R&D team, we offer specialized custom formulation services. We can precisely adjust core parameters such as hydroxyl value, viscosity, and acidity to match your specific manufacturing requirements.
Blowing Agent Compatibility: Exhibits smooth integration with pentane and other hydrocarbon blowing agents, creating a stable emulsion that prevents phase separation in the holding tanks.
Improved Green Strength: Accelerates curing during panel lamination, allowing for faster demolding times and increased daily output on the factory floor.
Good Dimensional Stability: The rigid polymer matrix prevents foam shrinkage or warping, even when exposed to severe temperature fluctuations.
Enhanced Flame Resistance: The inherent aromatic structure naturally promotes char formation upon heat exposure, acting as a physical barrier against flame spread.
Fine Cell Structure: Produces micro-cellular foam with high closed-cell content, trapping blowing agents effectively to improve overall insulation performance.
Good Adhesion to Metal Facings: Creates a strong, permanent chemical bond with steel and aluminum substrates, preventing delamination over the panel's lifespan.
These precise characteristics are absolutely critical for PIR panels that demand high compressive strength to bear structural loads, low thermal conductivity for superior energy ratings, excellent fire performance, and stable foam processing on high-speed lines.
Understanding the exact physical specifications is vital for calibrating your metering equipment and ensuring optimal reaction kinetics. The PS-2412/2402 series is manufactured with tight tolerances to guarantee predictable expansion and curing rates. Below are the standard physical parameters that define the handling and processing behavior of this transparent liquid at room temperature. The controlled viscosity ensures smooth pumping through standard mixing units without causing excessive backpressure, while the strictly managed moisture content prevents unwanted side reactions with isocyanates.

Developing the perfect polyisocyanurate (PIR) matrix requires a delicate balance of multiple chemical components. To simplify your procurement and testing workflow, we provide a comprehensive one-stop auxiliary material supply. Alongside our premium polyester polyols, we supply perfectly matched polyurethane catalysts (including TEDA and PC series) and high-efficiency flame retardants (such as TCPP and TEP). A common PIR panel formulation using this polyester polyol may include:
Component | Parts by Weight (pbw) |
|---|---|
Polyester Polyol PS-2402N/2412 | 60–80 |
Polyether Polyol | 20–40 |
Cyclopentane | 10–18 |
Silicone Surfactant | 1.5–2.5 |
PIR Catalyst Package | 3–8 |
Flame Retardant | 10–20 |
Polymeric MDI | Index 220–320 |
The exact formulation depends on several critical operational factors:
Target panel density and weight requirements
Specific regional fire rating requirements and building codes
Whether the manufacturing process uses a continuous vs discontinuous line
The choice between pentane or HFO blowing agent systems
The required lambda value (thermal conductivity) for the final product
Transitioning to aromatic polyester polyols like XF-2402N yields significant operational and economic benefits for panel manufacturers. Beyond the technical upgrades, this product offers a compelling investment return. It delivers the same, if not superior, foaming efficiency and thermal insulation performance as top-tier Western brands, but allows procurement teams to reduce comprehensive raw material costs by 10% to 20%. Crucially, this cost optimization can be achieved without the need to modify your existing production lines. Compared with standard polyether polyols, it provides:
Better Fire Performance: Meets strict building safety codes by significantly reducing the heat release rate during combustion.
Higher Char Formation: Creates a dense carbonaceous crust when exposed to fire, protecting the underlying foam core from thermal degradation.
Higher Rigidity: Enhances the load-bearing capacity of the final panels, allowing for longer spans between supports in building construction.
Improved Thermal Resistance: Maintains exceptional R-values over decades of use, resisting the gradual loss of insulating gas.
Better Dimensional Stability at Elevated Temperatures: Prevents panel deformation or blistering even when dark-colored metal facings are exposed to intense summer sunlight.

Proper handling and environmental control are essential to preserve the chemical reactivity of the polyol. We offer standardized, secure packaging options designed for safe international transit and easy warehouse handling. The material is supplied in heavy-duty 200KGS/DRUM or high-capacity 1000KGS/IBC totes, ensuring it remains uncontaminated by ambient moisture during shipping.
XF-2402N has a certified retest period of 12 months in unopened containers. Storage in sealed containers at temperatures of 60-95 °F (15-35 °C) is highly recommended. Prolonged exposure to temperatures below this range may cause temporary viscosity increases, requiring gentle warming before use, while excessive heat could compromise long-term shelf life. Always ensure drums are tightly sealed immediately after partial use to block atmospheric humidity.
