How temperature and pressure effects your seals

    How temperature and pressure effects your seals


Some form of O-ring, seal, bonding, mastic or enclosure is in almost every product and piece of equipment sold worldwide.  The most common reasons for this are preserving and protecting by keeping out water vapour, hydrocarbons such as greases, CO2 or other contaminants. But all seals are affected in this task not just by the materials themselves but also by the twin factors of temperature and pressure.

Versaperm's vapour permeability systems can measurement how well they work for materials and seals across a very wide range of temperatures and pressures – from -80 to 1100C and from 0-300bar. It work for water vapour, grease, hydrocarbons, aromatics, CO2, solvents and every single vapour in general use. This gives designers and manufacturers the ability to test and effectively eliminate problems across almost all standard and most non-standard 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.
