Materials

British Gaskets Ltd provides a comprehensive range of materials for processing into Gaskets and Rubber Moulded components.

Gasket Materials

The manufacture on high temperature Mica laminated materials are manufactured under tight controls at our Sudbury Manufacturing site. We also offer our own range on Non-Asbestos gasket materials that are formulated to the latest requirements. High quality compressed sheets for gaskets made of mineral fibre, aramide and dispersed inorganic loads mixed in a matrix of type SBR rubber.

This material has got exceptional flexibility and behaviour on cutting what add to its characteristic of under-control swelling in oils making a material with good suitability for the automotive industry and machinery construction for general use. It has good resistance to compression, excellent adaptability and low gas permeability.

Rubber Materials

Over the last 80 years British Gaskets Ltd have developed over 600 compound formulations and manufactured components in all the common thermoset rubbers such as SBR, Neoprene, EPDM, Natural, and Nitrile; also in highly specialised polymers.

Many of these materials are produced with in the group using bespoke equipment: These include: K4 internal mixer, mill room & test laboratory; injection and compression presses from 20 tonnes to 500 tonnes capacity; and composite bonding of rubber to metal, plastics and fabrics. Some of which are listed below:
