XF-235 Polyester Polyol for Sandwich Panels

XF-235 is an oligomeric polyester polyol specifically formulated for the production of sandwich panels. With a hydroxyl value of 230-245 mgKOH/g and acid value ≤2.0 mgKOH/g, it delivers consistent reactivity and dimensional stability. Its low moisture content (≤0.15%) ensures predictable foaming behavior, making it a reliable choice for manufacturers seeking uniform panel density and thermal insulation performance.

Key Selling Points

  • Precise hydroxyl value 230-245 mgKOH/g: Ensures consistent cross-linking density for uniform sandwich panel cores.
  • Low acid value ≤2.0 mgKOH/g: Reduces potential corrosion and improves storage stability of the polyol blend.
  • Moisture ≤0.15%: Minimizes undesirable side reactions during foaming, enhancing reproducibility.
  • Viscosity 10500±1500 CPS at 25°C: Facilitates reliable pumping and mixing in automated sandwich panel lines.
  • Proven in sandwich panel applications: Supports thermal insulation and stable foaming in normal production conditions.
