Plastics & Rubber Permeability Testing
When it comes to the permeability of gases and vapours, many plastic and rubber products are fairly poor at keeping them in or out – and prove a considerably worse barrier than they do to liquids. This makes a vital difference in their physical properties – not just as sealants, but also in the way they handle, print and perform in their day-to-day working lives.
Our permeability meter can measure the permeability of plastic and rubber seals, material samples, containers and finished products for water vapour, hydrocarbon and a wide range of other gases, including O2, N2, CO2 and He.
Our latest range of permeability measurement equipment and permeability sensors provide fast and accurate measurement - usually in the parts per million range, (parts per billion with some gases). Conventional gravimetric techniques take several days or weeks, but using our plastics and rubber permeability testing equipment takes from as little as 30 minutes for some materials.
Permeability in Plastics and Rubber applications
A wide range of plastic and rubber products require testing for permeability as, although they present a high permeability barrier to most liquids, many are very poor at preventing the flow of vapours.
