Plastics. Polyols for use in the production of polyurethane. Determination of hydroxyl number Ingestion-build-266356 - freezer to microwave usage1 Scope This document specifies two methods for the measurement of the hydroxyl number of polyols used as polyurethane raw materials. It is necessary to know the hydroxyl content of polyols 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. Method B is intended for polyether polyols,
