In‑house formulation and compounding provide the capability to tailor materials to match application requirements.
The science of compounding is regarded by many as a ‘black art’ with technologists worldwide striving to perpetuate this mysticism. Although many manufacturers may base their compounds and seals on the same polymer, the end results can be vastly different performance characteristics - in extreme cases as disparate as short-term failure compared with long-term reliability.
Working with a partner renowned for materials expertise as well as application specific knowledge can go a long way in helping to extract the maximum benefits of elastomer performance. At our Materials Technology Centre in the UK, we develop and compound our own elastomer materials, holding over 300 unique formulations including many bespoke developments for specific industries and customer applications.
Having the capability to formulate and compound our own materials gives us total control and traceability through every stage of the manufacturing process. Coupled with our comprehensive testing facilities for both materials and end products, this offers customers total peace of mind the our solution will perform as required.
Hydrogen presents a new and unique set of challenges. Materials need to be tested and evaluated, with selections supported by evidence.
A range of industry leading materials specified by OEMs and third party and validated to the toughest of the industry's test and approval regimes.
USP Class VI and FDA 21 CFR 177.2600 compliant elastomers for use in sealing duties of biopharmaceutical processing applications.
James Walker holds a respected reputation as a leading force in the application of materials technology to provide effective solutions to operational issues in critical nuclear applications.
Our O-ring range includes metric and inch sizes to a range of international, national and industry standards, manufactured in a variety of general and high performance elastomers to suit the vast majority of industrial and specialised applications.
Our global reputation for elastomer technology makes us the first port of call for end-users and equipment OEMs involved in both sub-sea and land-based production and exploration, with the vast majority of products we manufacture being proprietary technology, providing specific benefits to individual customers.
Whilst a decision on the proposed PFAS regulation, and the likely timeline for implementation, are still being considered by the ECHA, James Walker is proactively looking at, and qualifying, alternative materials and working with its suppliers to ensure sealing materials are available that will offer the required levels of performance and be compliant with any proposed regulations.
