P & P Technology Ltd is a specialist manufacturer of EMI and RF shielding and screening products. From attenuation vents and windows to knitted wire mesh and conductive wrapped fabric gasketing, we have all your EMC compliance requirements covered.
Established in 1989, P & P Technology Ltd has more than 20 years of experience designing and manufacturing specialist shielding and screening products, making us well placed to offer bespoke solutions to guard against a range of climatic and environmental conditions.
In a relatively short time, P & P Technology Ltd has grown to become one of Europe’s leading manufacturers of radio frequency and electromagnetic compatibility shielding products. Today we’re able to offer our customers a diverse range of vents, strips, tapes, wires, mesh and gaskets.
At our production facility in Essex we manufacture a huge range of shielded windows, vents and gaskets, almost all of which can be completely customised according to your requirements. An ISO 9001:2008 accredited quality management system ensures all standards are met and product quality maintained.
We are able to provide a fast and efficient response to virtually all shielding problems, and can offer a range of services to help you achieve compliance with the EC Directive on Electromagnetic Compatibility (EMC).

Aluweave is a highly conductive gasket medium produced by filling a woven aluminium mesh with silicone, fluorosilicone or neoprene rubber. It is ideal in situations where thicker EMI gaskets are unsuitable - however, because it is woven, Aluweave is unsuitable for ‘landwidths’ of less than 3mm for die-cut gaskets.
Aluweave is available in two thicknesses (0.4mm and 0.5mm) and is generally supplied in pre-cut gaskets constructed in accordance with customer requirements. It can also be supplied in sheet form.
In situations where the vents may be exposed to the elements they can be fitted with ‘slant’ honeycomb, which has a downward facing aperture to prevent the entry of rainwater. This has the added benefit of directional airflow and increased attenuation due to the higher aspect-ratio of the cell structure.
Exshield conductive gaskets are made from silicone-containing metal powder fillers which combine to offer high levels of attenuation with outstanding environmental shielding and conductivity. Customers can choose from a variety of filler materials, from nickel to pure silver – the choice of material depends on the application you have in mind. Also available are fluorosilicone variants for use in the presence of hydrocarbon contamination.
Exshield was initially developed for high performance shielding in military applications. However, the introduction of low cost fillers has made them accessible to the commercial sector, meaning they are now used in a variety of applications where environmental and EMI screening is required but where space restrictions or stringent environmental protection necessitates a small cross section profile.
Offering a cost-effective solution to EMC shielding, our conductive foil tapes can be used to seal joints on enclosures and for ground termination between panels in shielded rooms. Tapes are available in copper and aluminium, both of which have a conductive adhesive for fixing.
We also offer bake and peel conductive foil tape, which is commonly used as an alternative to selective plating or chromate conversion on painted surfaces. The tape is fixed in place prior to painting – once painting and baking are complete, the peel off mask can be removed to expose a conductive foil surface to which an EMC gasket may be fixed.
As well as gaskets for electromagnetic shielding, P & P Technology offers a full range of non-conductive gaskets for use in applications where only an environmental seal is required. Non-conductive gaskets produced by P & P Technology are supplied complete as labelled and bagged kits. They can be die-stamped according to customer requirements, with or without a self-adhesive backing. Custom jointed O-Rings are also available.
Non-conductive gaskets are typically made with silicone, neoprene or EPDM. These are available in fire retardant variants to UL94-V0 and UL94-HF1. Carbon loaded silicones are also available for ESD applications.
