Vapour permeability systems
02 December 2020
Some form of O-ring, seal, bonding, mastic or enclosure is in almost every product and piece of equipment to preserve and protect by keeping out water vapour, hydrocarbons such as greases, CO2 or other contaminants. All seals are affected not just by the materials themselves but also by temperature and pressure.
Versaperm’s vapour permeability systems can measure materials and seals work across a wide range of temperatures and pressures – from -80 to 1100˚C and from 0 to 300bar. The systems work for water vapour, grease, hydrocarbons, aromatics, CO2, solvents and other vapours in general use. This gives designers and manufacturers the ability to test and effectively eliminate problems across almost all environmental and operational conditions. The system can also simulate diurnal, seasonal and other changes.
The Versaperm equipment achieves results that are accurate in the PPM (Parts per Million) to PPB ranges. It can optionally measure several samples, seals, enclosures or products at a single time.
The company also runs consultancy and laboratory services that offers advice on permeability in complex cases or where the volume or logistics do not mandate a dedicated instrument.
