Plastics. Thermoplastic polyurethanes for moulding and extrusion - Distinction between ether and ester polyurethanes by determination of the ester group content Ingestion-build-44616 dark-room contrast ratio1 Scope This part of ISO 16365 specifies a method for the determination of esters including ester thermoplastic polyurethanes (TPU) and ether TPU for quality control without the necessity of sophisticated instrumentation and avoids or minimizes long term microbial testing for TPU materials. The method described is used to distinguish major TPU types and characterize TPU mixtures. The method is applicable to all linear polyurethanes based on 4,4
