ActivePlastics - Polyether polyols - Part 3: Determination of hydroxyl number
塑料 聚醚多元醇 第3部分：羟值的测定
Application Summary AI generated
This standard specifies the test method for determining the hydroxyl number of polyether polyols, which is a key parameter indicating the concentration of hydroxyl groups in the material. It is applied in the quality control and formulation of polyurethane raw materials, particularly for flexible and rigid foams, coatings, and elastomers. The method is used by manufacturers and testing laboratories to ensure consistent reactivity and performance in downstream polyurethane production processes.
