Description
Extended applicationInverted Cup Method Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate.
NOTE: inverted cups are required Artificial Skin Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test water vapor permeability of artificial skin Cosmetic Water vapor permeability of cosmetics Aseptic Films Aseptic wound protecting films, medical plasters and protective clothing materials LCD Display Water vapor transmission rate of LCD display and its relevant sheet Solar Back-sheets Water vapor transmission rate of solar Back-sheets and its relevant sheet Paint Film All types of paint films Biodegradable Films Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films
Technical specifications
