QB/T 4346-2012 (English Version) PDF

Scope: This standard specifies the classification, requirements, test methods, inspection rules and marking, packaging, transportation and storage of dry-process polyurethane films for fabric composites. This standard applies to polyurethane resin, colorants, and additives as the main raw materials, using release paper as the carrier, dry coating, and finally peeling off the polyurethane coating and the release paper for lamination with fabrics. of film.
