PU Coating Performance Testing and Characterisation
topic
PU coated fabric performance characterisation measures hydrostatic pressure resistance by Suter test, water vapour permeability by gravimetric cup or desiccant method per ISO 11092, flex cracking resistance by Bally flexometer or Maeser flex tester, peel adhesion between PU and substrate layers, and surface abrasion resistance by Martindale tester, with test results compared against application-specific specifications for each end use from outdoor apparel to footwear and upholstery.
Role
Verifies PU coated fabric performance against the technical specifications required for each application through standardised testing that measures the waterproofness, breathability, and durability properties that determine suitability for outdoor apparel, footwear, and upholstery applications, with comprehensive performance characterisation being required for customer technical approval and for validating that process changes maintain the established performance profile of approved products.
