Application
The VIP 6A-GM Water Vapour Transmission Rate Tester is a high-efficiency, intelligent instrument designed for the precise determination of water vapor transmission rates in plastic films, composite films, and various packaging materials. This equipment is widely used in medical, construction, and packaging industries to ensure material performance and quality.
Compliance Standards
- ISO 2528
- GB 1037
- GB/T 16928
- ASTM E96
- ASTM D1653
- TAPPI T464
- DIN 53122-1
- JIS Z0208
- YBB 00092003
Applications
- Films: Plastic films, composite films, geomembranes, coextruded films, aluminized films, aluminum foils, and breathable waterproof films
- Sheeting: Engineering plastics, rubber, and building materials (e.g., PP, PVC, PVDC)
- Paper and Paper Board: Paper, aluminum foil paper, and Tetra Pak materials
- Textiles and Nonwovens: Waterproof breathable fabric, non-woven fabric for diapers and hygienic products
- Extended Uses: Artificial skin, medical products, solar back-sheets, LCD monitor films, paint films, cosmetics, and biodegradable films
The gravimetric method involves generating a consistent humidity difference between two sides of the test specimen at a controlled temperature. Water vapor permeates through the material, and the rate of transmission is determined by measuring changes in the specimen’s weight over time.
