Product Summary

XF-390 is a medium-hydroxyl polyester polyol with 400±20 mgKOH/g, designed for PIR systems and sandwich panels where balanced reactivity and flow are essential.

Key Selling Points

• Hydroxyl value 400±20 mgKOH/g: balanced cross-linking for good mechanical properties and insulation.
• Lower viscosity (2000±500 cP at 25°C): excellent flowability and mixing with other components.
• Low acid value (≤2.0 mgKOH/g): reduces catalysis interference, ensuring consistent foaming.
• Moisture ≤0.15%: avoids CO2 blistering, improving foam homogeneity.
• Proven in PIR production system: satisfies high flame retardant and low odor requirements (based on scenario).
