Solving Critical Manufacturing and Materials Problems

Almost every product has an outer case, enclosure, skin or package and you would think would keep things in or out, right?  Sadly not.  For example, underground electronics in a leakproof silicone case will fail within days because water, as a vapour, can pass (or permeate) through it almost as if it wasn’t there.  Then the vapour condenses inside as liquid water and causes problems.

The same is true for virtually every product in any enclosure, as all gases can permeate through all materials, just at different rates.  The very act of manufacture, moulding, bending or joining can easily make things even worse by a factor of 4! .  The answer lies in testing enclosures and the materials – and that’s where Versaperm comes in.

Versaperm’s range of systems can measure this problem for just about any material, enclosure or structure for virtually any gas – including water vapour, CO2, hydrocarbons, greases and oxygen.  It is fast, accurate and gives consistent results over a wide range of physical conditions.  Accuracies are usually in the Parts Per Million (PPM) to Parts Per Billion range.

The latest computer-controlled Versaperm systems are highly automated making them easy and quick to use.  They can include full control over an exceptionally wide range of temperatures and pressures.

Vapour permeability issues cost the UK several billion pounds a year.  Problems range from electronics that fail, to drugs that lose potency, equipment that jams, products that “go-off” and a whole set of problems caused by things that aren’t sealed with the correct material.

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


* E.g.  Radon is a proscribed gas and it is only legal to measure it in properly licenced and safe laboratories.
