Our knitted wire mesh has many uses in both existing and new horizon electrochemical industries such as fuel cell production and the latest generation of battery developments. Knitted wire mesh is a strong, flexible and resilient material, created from a web of interlocking wire loops, that offers utility in applications where harsh environmental conditions preclude the use of other materials.
The flexibility (ability to be bent without breaking) and malleability (the ability to withstand plastic deformation without fracture) of our products can be designed according to customer needs. Through a careful selection of materials, mesh structure, and tooling design, we can produce mesh components in an almost limitless range of shapes including sheets (blankets), highly flexible hollow mesh tubes, and 3-dimensional rigid structures such as prisms, cubes, spheres and doughnuts, etc.
Resilience can be defined as the ability of a material to absorb energy when deformed and to release that energy on unloading. The feature is particularly beneficial in applications such as seals (often incorporating resilient cores), gaskets and vibration isolators for use in both high and low temperature environments. Our engineers can work with customers to select the materials and manufacturing methods required to configure a product that will perform to the most exacting specifications.
Materials can be selected and processed, in any of a huge number of possible variants, to produce knitted mesh components that will withstand the conditions experienced in the most arduous of operational environments. Corrosion resistance and fatigue tests at up to 1,000°C can be conducted on-site with products typically being used in aerospace, automotive, refractory, cryogenic and marine environments.
High Surface Area
Knitted mesh can be processed from a wide variety of materials to produce densely packed components with high surface area per unit weight or volume. Surface areas of >30,000 m2 per m3 of compressed material can be achieved which is equivalent to >5 m2 per kg of stainless steel. In cost terms this feature of knitted mesh compares very favourably to other technologies and is utilised in applications such as catalyst substrates or where rapid heat transfer from a fluid is required.
A feature of knitted wire mesh is its ability to conduct an electric current. The specific conductance and heat retention and dissipation characteristics, together with the type of wire and its cross-sectional area, are key selection and design criteria. The wire can be insulated by a variety of materials with the most common uses being in heating and security applications.
Crimped knitted mesh is a conductive, compressible fabric where its resilience, heat & corrosion resistance and excellent geometric properties, render it an ideal media for the electrical contact and compensation elements used in alkaline electrolysis processes within the Chlor-Alkali, Fuel Cell, Power-to-Gas and the Water Electrolysis industrial sectors.
Such elements, manufactured from a conductive metal that is resistant to electrochemical attack, can be used to optimise the electrical & pressure contact between cells, divider stacker plates and membranes & diaphragms in electrolysis cell stacks & modular cell cartridges. You can contribute to the circular economy, improve your environmental credentials and enhance your corporate social responsibilities by selecting our recyclable and eco-friendly mesh products.
We coat steel to enhance its corrosion resistance or to modify its physical properties
Increasingly, the Chlor-Alkali industrial electrolysis process requires zero-gap technology. This utilises an elastic element in the design of the electrolysis membrane cell which assists in minimising volt drop and making the current distribution uniform – our range of crimped nickel meshes are ideal for these applications.
Power to gas
In the same way that other technologies utilise the industrial electrolysis process, Power to Gas systems may also require conductive and corrosion resistant elastic elements in their design – our range of crimped nickel meshes are ideal for these applications.
Some electro-chemical energy conversion devices that produce electricity, water and fuel, require an electrolyte resistant compressible element to optimise electrical & pressure contact between fuel cell components – our range of crimped nickel meshes are ideal for these applications.
