| Company Description |
|
Kemtron Ltd is a specialist manufacturer of RFI/EMI shielding gaskets and components and has been providing customers with excellent solutions for more than 30 years.
Electronic devices are becoming more and more complex in the developing world and thus may be more susceptible to electromagnetic interference (EMI). RFI/EMI shields are commonplace for isolating components from one another and no one is better suited to creating solutions than Kemtron Ltd. Kemtron Ltd, based in Braintree, Essex, is known and respected globally for its quality and reliable products which are utilised in some of the most demanding industries in the world such as defence, aerospace, information technology, communications, electronics and more.
Kemtron Ltd's team of skilled engineers have years of experience in the industry and offer a trusted service to their customers. Engineers work closely with customers to create the very best shielding and environmental sealing programmes for the ultimate performance when meeting EMC shielding and environmental sealing requirements. Our technical advisors are located in different areas to respond to all RFI/EMI shielding enquiries quickly and efficiently. Our technical team will be happy to arrange a visit or discuss options with you over the phone in the first instance.

Kemtron Ltd's electrically conductive elastomer materials are suitable for many customer applications across a wide temperature range. Our conductive elastomers are manufactured from silicone and fluorosilicone and are loaded with highly conductive particles such as silver plated aluminium,
silver plated copper, nickel coated graphite and pure nickel. Our conductive elastomers are available in standard and custom configurations including extruded profiles, 'o' rings, moulded components, and flat sheets for die cut gaskets. The properties of our conductive elastomer materials enable resistance to compression, fuel oils and solvents.

All electronic equipment emits and receives some form of electrical interference. Our knitted wire mesh gaskets are created to produce high levels of EMI shielding performance in magnetic and electric fields. Our knit meshes are available in the following wire types: monel, stainless steel, solid mesh and tin plated copper clad steel. Knitted mesh gaskets can be supplied as solid mesh or knitted over elastomeric cores with or without environmental seal in continuous lengths or fabricated to custom designs.

|
Our solid and sponge silicone variants consist of vertically oriented monel or aluminium wires up to 140/sq cm. They combine excellent EMP survivability with a high level of effective RFI/EMI/EMP shielding. The wires are ideal for use as access panels, seals and connector gaskets and are available as sheet stock, strip or can be die cut to meet customer's individual design requirements. Different materials are available in varying thickness to accommodate most design requirements. Self-adhesive backing and compression stops or collars can be fitted to prevent over compression and fluorosilicone versions are available for use in environments where fuels/oils/ hydraulic fluids and other contaminants are present.

|
Our range of EMI shielding vent panels are designed to allow air-flow whilst preventing the transmission of electromagnetic interference. Our commonly used vent panels are made from aluminium or steel honeycomb panels mounted in an extruded aluminium frame. Honeycomb vent panels are used for applications for high level of air flow and shielding performance such as
in heating and ventilation systems, generators, engines and cooling high power systems. Our honeycomb panels are available in a range of thickness to meet different shielding requirements and protective grills are available for vulnerable areas together with dust filtration foams. Many
plated or painted finishes can be specified.

|
Our conductive fabric over foam gaskets are formed by wrapping a conductive fabric such as nickel/copper, silver plated polyester or nylon fabric over an open celled urethane core and are designed for shielding in various electronic enclosures. We supply various profiles such as rectangular, D shape and low compression/deflection C shape seals. These ranges provide excellent EMI gaskets with low compression sets and excellent abrasion resistance for high cycling and wiping applications. Most meet UL94V-0 and are available as strips, cut to length or die cut.

We supply conductive and non-conductive elastomer silicone compounds that are deposited as a gasket directly to the enclosure by XYZ CNC technology. The dispensing machine deposits the gasket by following a pre-determined CNC path to provide accuracy and repeatability. This process is advantageous in many ways: materials are one-component room curable, small gasket land is required, there are low set-up costs, no material waste, excellent EMI shielding, it can be applied to metal and plastic components, and more.
Form in place gaskets can be very intricate to suit enclosures with little space for a traditional gasket such as thin walled multi compartment housings providing an EMI and environmental seal.

The shielding of optical windows is created by embedding
finely woven metal mesh made from fine stainless steel or copper wire mesh.
Meshes are made to various sizes and thickness and can be coated and blackened
to prevent surface reflections. Shielding and screening of optical windows can
also
be reached by the application of a transparent vapour deposited conductive
coating such as Indium Tin Oxide or Gold to the surface of the optical
substrate. Our EMI shielded windows are commonly requested for display services
or inspection panels where they provide optimum transparency and
EMI shielding.

We supply high quality single component RTV (room temperature vulcanising) silicone adhesives that are electrically conductive. Our Kembond range of adhesives are available with a range of fillers such as silver and nickel coated graphite which are designed to be used as a thin bond between two components. Caulking compound can also be supplied to fill larger gaps and voids, surface imperfections or to hold conductive gaskets in position. Our Kembond RTV adhesives are available in standard manual or pneumatic 10ml syringe barrels for direct application. We also supply two component electrically conductive epoxy adhesives for use with most common substrates.
