Water Vapor Permeability & Absorption Tester GT-KC55
Application
Function 1: Under the standard stipulated (23 ± 2)°C and the (50 ± 5)% RH environment, to test water vapor permeability for vamp and upper shoe materials ( including surface and lining );
Function 2: To determine the coefficient of water vapor absorption on leather and non-leather upper. The equipment is basically composed by six stainless steel cups that are inserted in plastic base which maintain them in vertical position.
Function 3: Water Vapor Permeability and Absorption Tester to determine the resistance of a material to cracking or other types of failure at flexing creases. The method is applicable to all flexible materials and in particular leathers, coated fabrics and textiles used in footwear uppers.
