NEW DEVELOPMENT AT BAYER

摘要

Bayer MaterialScience has developed the new thermoplastic polyurethane(TPU)Desmopan~R DP 6580A MVT(Moisture Vapour Transmission)for the production of films used to coat fabrics.The material's main feature is its unusually high water vapour permeability which,in the case of a 15 mu m film thickness,amounts to 5,400 grams per square meter per day at 38 deg C and 90% relative humidity according to DIN Standard 53122.
