Gaskets & EMC Products

Bovill & Boyd have been supplying huge numbers of Gaskets into all sorts of industries for many years. Gaskets come in a large variety of forms to suit many different applications. We can provide a comprehensive range to suit your specific requirements as illustrated below.

Softcut Gaskets

Softcut is a general term for gaskets that have been produced in any flexible material.

As part of the 4BG Group of companies our production facilities for soft cut gaskets are among the most varied in the gasket industry.

• Skilled hand fabrication
• Conventional Hydraulic Presses
• CNC Operated Milling Cutters
• Laser Cutting
• Water Jet Cutting

We can produce small prototype quantities up to large production runs in a bewildering number of materials including:

• Non-asbestos
• Graphite Rubbers
• PTFE & Expanded PTFE
• Papers
• Felt
• Corks 
• Mica and mica laminates

Production is not limited to straightforward flat cut parts. We can also form parts into various shapes. Material such as Leather is still used to produce cup washers for valves for instance and electrical insulation materials are often produced with bends and creases to give a continuous electrical resistant barrier inside many pieces of equipment.

Screen Printed Gaskets are a specialised type of gasket. The basic concept of a screen printed gasket is that a fine bead of silicon is applied to a carrier material. This type of gaskets is best used on very intricate applications such as valves and hydraulic applications.

We also supply conductive / non conductive elastomer seals and gaskets in silicone / fluorosilicone typically used in EMC applications.

If you require some design input we are only too happy to help in whatever way we can. Our experience in this industry will allow us to make recommendations of suitable materials for your application. Why not give us a try?

Bovill & Boyd supply a wide range of EMC products manufactured from conductive elastomers typically used for shielding electronic enclosures and connectors to achieve electromagnetic compatibility.

Bovill & Boyd offer electrically conductive elastomer gaskets, that can be corrosive resistant, environmentally sealing and cost effective, with sealing levels up to IP68.

A variety of materials to suit customers strict requirements, can be fully moulded into complex shapes, extruded into specific profiles or standard cord or flat gaskets, cut from sheet.

Gaskets can be fitted with compression stops to prevent overtightening of screws.

We have a full range of connector gaskets, including Mil spec.

Total Environmental & RFI Protection  

The Duo- Seal offers a compact , space -efficient gasket. Comprising two different materials (a conductive and non-  conductive silicone or fluorosilicone ), the duo seal can offer environmental , chemical and RFI protection in one easy to assemble solution. The Duo- Seal is consistently used by our military and aerospace customers, on applications where high performance and environmental protection cannot be compromised.

This is backed up with a statement from our customer “ The Duo -Seal is a fit and forget seal”

Up to IP68 sealing

Total galvanic protection achieved

Compact use of single groove

Flame retardant capability

Can be designed to suit hardware

Our product range includes extruded and moulded conductive silicones / fluorosilicones for environmentally harsh requirements.

For less harsh environments we can provide various solutions including vent panels, finger strips, fabric wrap & conductive foams.

We can also offer Flame Retardant materials when required.

Dependent on environment, we can help guide you to the product most suitable for your application. All of our EMC products can be custom made and tailored to suit specific requirements. Please contact us for more information.
