Versaperm Vapour Permeability measurement


How to avoid the next crash!
Permeability measurements for the Aerospace & Automotive industries


Aerospace permeability

Permeability is vital in real-world applications as it dramatically affects characteristics such as whether systems leak, components rust or fuel tanks explode, it also controls print- and paint-ability along with the shelf life of food & pharmaceuticals.  It is critical to the quality control of a huge range of products and processes.

It can be vitally important that parts of a car, aircraft, missile etc don’t permit hydrocarbons or water to leak as this can catastrophically affect the computers, components and safety of a vehicle.  It’s also a legal requirement in most countries.

Design problems usually occur not through leakages, but because hydrocarbons and vapour water can permeate through a component’s materials, barriers and walls.  Getting it wrong can be disastrous; getting it right can avoid a crash course in testing!

Conventional gravimetric permeability measurements on components, materials, assemblies, tanks, pipes and seals are slow and expensive, taking days, weeks or even months - and they are not always either accurate or consistent.  Versaperm’s permeability measurement equipment, however, is fast, accurate and gives consistent results under a range of physical conditions. Accuracies are in the Parts Per Million (PPM) range for many materials and gasses.

Versaperm’s system can optionally be configured to measure permeability for a variety of gasses including hydrocarbons, solvents, oxygen, carbon dioxide, helium and water vapour.  The equipment is automated and easy to use.

Versaperm also offers a laboratory testing service and technical consultancy for companies that test too few samples to make the purchase of equipment viable.
