Ceramic Fibre Washers

Advanced Seals & Gaskets Ltd sources the highest quality materials for use in specialist sealing, insulating and gasketing applications and as such makes them one of the UK’s leading washer and gasket manufacturers and suppliers.

One such material is Ceramic Fibre Jointing Paper, also called Ceramic Fibre Paper. Ceramic Fibre Jointing Paper is manufactured in thicknesses between 1mm and 8mm, widths of up to 1260mm and various roll lengths of 40meters to 330 meters depending on the thickness from which washers can be cut.

Our Ceramic Fibre Washers are produced on-site using drawings, samples or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. Depending upon the size and quantity of washers required, one of many presses or kiss-cut machines can be used to manufacture the final product, from one-off samples to multi-thousand batch runs.

Our Ceramic Fibre washers can be supplied plain or with a choice of finishes including foils or self-adhesives, depending on the size and quantity of the gasket, they can be supplied as loosely packed parts, or kiss-cut on rolls.

    What are Ceramic Fibre Jointing Paper Washers?

    Ceramic Fibre Jointing Paper is manufactured using a combination of papermaking techniques, ceramic fibre (alumina silicate) and organic binders. The binders are carefully selected to ensure they do not release unpleasant odours or toxins when they burn during application. The process of manufacturing this material ensures an accurate thickness and uniform structure is formed to ensure the reliability of cut products including washers.

    When cut into a ring with an outer diameter (OD) and inner diameter (ID) measurement, they form a washer. Fibre Jointing washers can be placed between two surfaces creating a level surface, acting as a spacer or placed between a nut or bolt to spread the pressure when tightened.

    Why use Ceramic Fibre Jointing Paper?

    One type of washer manufactured by ASG are those manufactured using Ceramic fibre paper, which is an extremely flexible, lightweight material with a uniform fibre structure offering resistance to thermal shock, fire and provides exceptional tensile and dielectric strength.

    When used with naked flames, once ignited, the binding agents in these washers will burn out, leaving the fibres behind which act as a thermal barrier at temperatures up to +1260°C.

    Ceramic fibre jointing paper washers can be used as a replacement for asbestos (the original toxic type) such as for boiler or pipework insulation in very high-temperature environments.

    Benefits of using Ceramic Fibre Jointing Paper

    • Works in temperatures up to +1260°C.
    • flexible and lightweight.
    • Insulates against thermal shock and vibration
    • Easy to cut.
    • Asbestos free
    • Some chemical resistance
    • Low thermal conductivity

    Where can Ceramic Fibre Jointing washers be used:

    • Wrap around pipework
    • High Temperature gasket applications
    • Seals in ovens, kilns, furnaces and boilers
    • Fire protection
    • Automotive heat shielding and silencer insulations
    • Molten metal transfer systems
    • Expansion joints

    Advantages of using Ceramic Fibre Jointing Paper Washers

    Washers manufactured using Ceramic Fibre Jointing Paper offer a number of advantages, mainly the materials ability to perform in temperatures up to +1260°C, therefore can be used in applications where there are extreme high temperatures, open flames or sparks.

    Ceramic Fibre Jointing Paper washers can be used as electrical or high pressure insulation, refractory or hot top linings, heatshiedling (crucial in the automotive and aerospace industries), as shielding or high temperature washers.

    Ceramic Fibre Paper is manufactured in a range of roll lengths and thicknesses, making it suitable for converting in very large or small washers.
