Note1: Herein the “Humidity” means the humidity difference between the two sides of the film specimen. The humidity in the test chamber is 10%~30%RH accordingly.

Note2: Herein the “Humidity” means the humidity difference between the two sides of the film specimen. The humidity in the test chamber is 10%RH-98%RH when the temperature is 15 to 40 °C, 10%RH-90%RH when the temperature is 45 °C, 10%RH-80%RH when the temperature is 50 °C, 10%RH-70%RH when the temperature is 55 °C.

Principle

Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Application

This instrument is applicable to the determination of water vapor transmission rate of:

Basic Applications	· Films Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
· Sheeting Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC
· Paper and Paper Board Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials
· Textiles and Nonwovens Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products
Extended Applications	· 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
· Medical Products and Accessories Including plasters, aseptic wound protecting films, face masks and scar sticks
· Solar Back-Sheets Including solar back-sheets
· LCD Monitor Films Including LCD monitor films
· Paint Films Test water vapor permeability of various sorts of paint films
· Cosmetics Test water vapor permeability of cosmetics
· Biodegradable Films Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films
