High Purity Polyether Polyol for Premium PU Insulation Board Making

High Purity Polyether Polyol for Premium PU Insulation Board Making. Moderate stable viscosity with smooth flow, controllable cream and gel time, perfectly matching high-speed continuous insulation board production lines to lower reject rates. Ready pre-blended polyether containing all additives like surfactant, catalyst and flame retardant; no extra compounding needed to save labor and stabilize batch consistency. Creates foam with ultra-low thermal conductivity and over 92% closed-cell rate, offering remarkable energy-saving insulation effect for buildings and cold storage. High crosslink density brings great compressive strength and ultra-low shrinkage, preventing warping, cracking or deformation after long-term use. Flexible adjustable flame retardant performance, available in B2 standard grade and customized B1 fire-resistant grade to meet global construction safety codes. Strong resistance to moisture, hydrolysis and temperature cycling, maintaining stable performance in humid outdoor environments and extending the service life of insulation boards. Flexible formula customization based on customers target foam density, hardness and production processes.
