This document specifies two methods for the measurement of the hydroxyl number of polyols used as polyurethane raw materials. The hydroxyl content of polyols are determined to properly formulate polyurethane systems. Method A is primarily applicable to readily esterified polyether polyols. It is also intended for polyols which have significant steric hindrance, such as those based on sugars.…
