Conductive silicone
The Conductive Silicone Range was originally developed for high performance shielding mainly for military applications. However, the introduction of lower cost fillers has now made them accessible to the commercial sector.They are used where environmental and EMI screening is required but space constraints or stringent environmental protection necessitates a small cross section profile, often fitted into a groove or channel.Our E Range gaskets are constructed from silicone containing metal powder fillers which combine to produce high levels of attenuation with excellent environmental shielding and a high level of conductivity. Many types of filler, from nickel graphite to pure silver, are available to suit a wide range of applications. There are also Flurosilicone variants for use in the presence of hydrocarbon contamination.
The E Range is best used where mating surfaces are smooth and well machined. They should be mounted to provide adequate volume for the material to deflect under pressure and should be compressed by between 8 and 20% of their relaxed height for solid sections and between 20 and 100% of the height of the hollow centre of tubular sections. Moulded 'O' rings, gasket profiles and sheet materials all have their own compression characteristics according to how they are mounted and do not comply with the guidelines above.
EC Series
For the EC series extrusions, a round or D section profile, fitted into a correctly dimensioned groove or channel will provide the most effective sealing and shielding performance. Fixing with any form of conductive adhesive is not recommended as this is likely to have an adverse effect on the environmental sealing.
EM Series
Our EM Series rubber gaskets are produced in flat or profiled cross sections to suit specific applications.
ES Series
The ES Series can be produced in sheet form or as diecut flat gaskets.

Elastomer-cored knitted wire meshes
P & P Technology's KE Series elastomer-cored knitted wire meshes consist of two layers of knitted wire over a low-closing-force rubber or elastomer core and offer the same shielding effectiveness of all-mesh types.

Conductive adhesive
The one-part conductive particle filled room temperature curing silicone rubber adhesives is available using standard silicone and flurosilicone base compounds combined with a selection of particle fillers to produce a readily extrudable paste which self-cures when exposed to atmospheric moisture.

Connector Gaskets
P & P Technology manufacture a wide range of connector gaskets, including precision diecut gaskets made from a selection of materials, both conductive and non-conductive. Gaskets can be tailor made to meet individual requirements.

Attenuation vents
P & P Technology's VH Series of lightweight aluminium honeycomb attenuatung ventilation panels comprise of forms of conductive airflow media retained within an aluminium extrusion. They are designed for use in racks and other forms of commercial enclosure.

Aluweave - versatile gaskets
Aluweave is a versatile, highly conductive gasket medium produced by filling a woven aluminium mesh with either silicone, flurosilicone or neoprene rubber. It is particularly useful where thicker gaskets are unsuitable but, because it is woven, it is unsuitable for 'landwidths' of less than 3mm for diecut gaskets. Surface irregularities should not exceed 0.05mm.

High performance RFI vents & filter composites
P & P Technology's VP Series of honeycomb ventilation panels can be custom manufactured from steel, brass or stainless steel. When selecting the material, corrosion resistance relevant to the application environment should be considered along with the attenuation requirements.

Edge bonded shielded windows
A low cost range of windows offering the same high level of EMI shielding performace as our range of fully laminated windows (WF Series) but with edge lamination only.

Airfilters with dustfield
Our VF Series of RFI vents combine the benefits of an attenuation vent panel with the properties of a dustfilter in a single frame, unlike the VB Series which utilises separate units fixed together in-situ.

Shielded windows
Fully laminated (WF Series) screened windows combine the physical strength and optical clarity of laminated glass or plastic with the shielding effectiveness of fine wire gauze.

Silshield - Oriented wires in silicone
Our S Range silicone rubbers combine excellent environmental protection with a high level of shielding effectiveness. These products incorporate a matrix of vertically oriented wires which pierce both flat faces of the elastomer and provide around 100 contact points per square centimetre.

Vent/filter composites
P & P Technology's VB Series of EMC vents / filter assemblies are composites of the VH Series honeycomb attenuation vents and demountable dustfilter panels containing a demembraned polyurethene filter media.

Knitted mesh with carrier
Our KM series gasket strip and frame materials consist of a slotted aluminium extrusion carrier into which a solid or elastomer cored knitted mesh gasket is clamped. These ready-to-fit, semi-rigid gasketing profiles help to avoid the problems often encountered when fitting adhesive-backed or plain mesh gaskets.

Monex - expanded monel foil
Monex is expanded Monel foil filled with silicone rubber. The exposed foil surface provides excellent conductivity combined with good corrosion resistance. Monex is also 'thin' gasket medium, similar to Aluweave, and is particularly suitable for connector or waveguide gaskets where a pressure seal and EMI shield is required.

Twinstrip knitted or cored mesh gaskets
Twinstrip is a combination of knitted or cored mesh gasket with a non-conductive environmental seal. The wire mesh types used are Monel, Aluminium, TCS and Stainless Steel and the permutations of wire and elastomer combinations are almost endless providing a wide range of environmental, water, dust and pressure seals.

Fully laminated windows
Fully laminated screened windows combine the physical strength and optical clarity of laminated glass or plastic with the shielding effectiveness of fine wire gauze.

Knitshield KP Series Knitted Mesh
Knitted wire meshes are produced from a single continuous filament and produce very high levels of EMI shielding performance when evenly compressed between two metallic contact surfaces.

Metweave - Woven Fabric Gasketing
P & P Technology's MW Series of ultra soft-fabric wrapped shielding profiles utilises a highly conductive and durable impregnated fabric formed around a sponge or foam core to create a very versatile low compression gasket medium.

Conductive adhesive
The one-part conductive particle filled room temperature curing silicone rubber adhesives is available using standard silicone and flurosilicone base compounds combined with a selection of particle fillers to produce a readily extrudable paste which self-cures when exposed to atmospheric moisture.
