Urine-absorbing aids for incontinence — Polyacrylate superabsorbent powders — Part 4: Test method for estimation of the moisture content as weight loss upon heating (ISO 17190-4:2020)
This document provides a test method for the evaluation of mass loss upon heating for cross-linkedpolyacrylate superabsorbent powders.This method is applicable to powdered polymeric superabsorbent materials that are free-flowing underthe specified test conditions. Substances other than water that are volatile in this temperature rangewill interfere. The onus is on the polymer formulator/ producer to decide if such interference is possibleand either exclude the method from use, provide an alternative or modify the method accordingly.
