Versaperm Vapour Permeability measurement


Anti-sogginess testing for quality control

Water vapour permeability technology experts Versaperm are offering a fast turn-around, economical testing service to determine the often critical permeability of a wide range of industrial, pharmaceutical and retail products. Water vapour can, for example, cause product failure, slash shelf-life and can even be diagnostic of compositional changes.

Because of the need for speed in QA and production situations, Versaperm has developed its own technology and equipment that gives very fast, highly accurate results - usually turned around within 24 hours. Conventional gravimetric testing can take days, and even weeks to measure the sample.

The company uses its own-developed WVTR (Water Vapour Transmission) equipment, which can produce accurate and reliable results to better than one part per million - sometimes in the parts per hundreds of million range. With some materials these results can be achieved in as little as 30 minutes, but even with hard to measure foils, results can normally be turned around in a day. Sensitivities are in the range 0.05 - 3200gm/m2/day.

As well as standard testing on products such as films and foils, dry coatings, pharmaceutical packaging, small bottles, small industrial objects, Versaperm has the facility to test unusual or hard to measure objects such as building materials, large bottles and containers, large industrial objects and once, even a pizza!
