HOW TO GET TESTY WITH US
Anti-sogginess testing for industry and research
Water vapour permeability technology experts Versaperm are offering a fast and economical testing service to determine
the often critical permeability of a material or product. Because of vapour, tubing and containers leak, products go soggy, paper jams in printers, chemical and
biological reactions occur, contact lenses hurt and the Quality Control (QC) function can be seriously degraded.
Water vapour is omnipresent and, more often than not, degrades products and results. Versaperm can test the
permeability of a huge range of materials and enclosures - from foil laminates to tubing and from paint to packaging, paper and pizzas. They can also provide
measurements of the equilibrium relative humidity (ERH) of substances that might otherwise be decomposed by normal water content measuring techniques.
The company has substantial testing and R&D experience and is always interested in the challenge of measuring the
leakage rates of new designs. Leakage can be measured under a range of temperatures.
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.
The service is considerably faster and more accurate than using conventional gravimetric techniques, which can take
days or even weeks.
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!
