One key sign of a product’s success is often the number of imitations it spawns – many of which are inferior low quality, low cost alternatives that may well have the same appearance as the real thing but offer performance way below that which is acceptable.
To help protect its own products from such imitations, James Walker has perfected a method of positive material identification for its range of Devlon thermoplastics, including Devlon V-API which is commonly specified for valve seat use in critical valve assemblies.
PMI Technology is a microscopic additive incorporated within the Devlon material that can be identified from the smallest sample of material – including fine swarf shavings. The additive can also be detected in parts that may have been melted or burnt during use.
The properties of Devlon are not in any way altered or compromised by PMI Technology, though its inclusion now means that genuine Devlon can be identified quickly and easily.
In safety critical applications such as valves, it is vital that the material specified is the material used. Devlon V-API with PMI Technology gives manufacturers and end users the peace of mind that they are using genuine Devlon material – particularly significant in an industry where increased occurrences of counterfeiting are an unfortunate and unwelcome reality.
In addition to having a material sample analysed at the James Walker Devol manufacturing centre, customers are also able to request a site visit from James Walker personnel for tests using portable PMI analysers – ideal in cases where immediate results are imperative or the material may already be installed in an assembly.
