ISO FDIS 16365-3

Description / Abstract: This part of ISO 16365 provides a method for determination of esters including ester thermoplastic polyurethanes (TPU) and ether TPU for quality control without the necessity of sophisticated instrumentation and avoids or minimize 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 on all linear polyurethanes based on 4,4'-diphenylmethane diisocyanate (MDI) and is intended e.g. to minimize long term tests related to microbe resistance and hydrolysis.
