PLASTICS AND RUBBER INSTRUMENTATION
Fast accurate measurement of the World’s most damaging contaminant – and its most beneficial!

Versaperm Limited, a world leader in water vapour permeability is launching an entirely new instrument for the fast and accurate measurement of water vapour permeability in plastic and rubber materials, products and containers.

The majority of films, plastics, coatings and polymers are impervious to liquid water, but many of them allow water as a vapour vapour to pass straight through. This can cause widespread problems – from packaged drugs loosing effectiveness through to equipment failing, or cornflakes going soggy.

Water is both the world’s most damaging contaminant and its most beneficial substance. Water vapour is both omnipresent and highly invasive.

Using materials with inappropriate vapour permeabilities costs the UK alone considerably over £100M every year and needlessly reduces the active life and effectiveness of a huge range of preparations.

The Versaperm WVTR (Water Vapour Transmission) MK VI meters’ highly automated computerised control can cope with several samples at a time - and still give a reading in as little as 30 minutes for some materials. The conventionally gravimetric measurement technique takes several days and gives significantly less accurate / reproducible results.

The MK VI needs very little re-calibration and requires, at most, minimal training to give results that can be accurate to better than one part per million (with some samples a few parts per hundred million). Sensitivities are typically in the range 0.05 - 3200g/m2/day.

A wide variety of options is available, depending on the specific applications, but both single and multi-sample systems, plus a range of measurement chambers and sensors can be supplied for testing samples from the size of a thimble up to a pallet load and beyond.

As well as vapour transmission, the equipment can be used to measure the Equilibrium Relative Humidity (ERH) of substances - that might otherwise be decomposed by normal water content measuring techniques. Additionally the instrument can be configured to measure the diffusion rates of most gaseous elements (water, O2, CO2 etc).

The company also operates a laboratory service to measure permeability for companies where the volume or logistics of measurements does not demand a dedicated instrument.
