Versaperm Vapour Permeability measurement

Sizzling seals and frozen flanges
Sealing under high and low temperatures & pressures

Packaging, Protection and Permeability




High and low temperatures and pressures are demand masters for seals to work under. O-rings, bonds, mastics, joints, flanges, and enclosures often play a critical or even safety critical role in everything from aerospace and engines to industry and icy environments. Seals are important in almost every product and piece of equipment sold worldwide, high and low pressures and temperatures, just magnify the problems. 

Most seals are designed to keep out water vapour or other contaminants, including hydrocarbons CO2, greases and gases.  All of these are affected, often dramatically, by temperature and pressure.

Versaperm’s high and low temperature and pressure vapour permeability systems measure how effective materials and seals are across a very wide range of temperatures and pressures, from -80 to 1100 C and from 0-300 bar. The systems work for every single vapour in general use* allowing designers and manufacturers to test materials, seals, components, enclosures across all standard and most non-standard environmental and operational conditions. This allows them, effectively, to eliminate sealing problems.

The Versaperm equipment is typically accurate in the PPM (Parts per Million) to PPB ranges and can test several products at the same time.  It can simulate diurnal, seasonal cycles and operational cycles.

Seals perform very differently under different conditions, and even more so under extreme or super-critical ones.  Such conditions are surprisingly common, for example in engines, cold storage and when using super-critical fluids, such as CO2 which is widely used due to its abilities to purify materials.

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.
