ISO-25761 › Plastics - Polyols for use in the production of polyurethanes - Determination of basicity (total amine value), expressed as percent nitrogen
The following bibliographic material is provided to assist you with your purchasing decision:
The method specified in ISO 25761:2014 measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to amine-based polyols, polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures of batch-to-batch uniformity and may be used to estimate reactivity in polyurethane reactions.
