    What Are Betaflex Fibre Jointing Gaskets?

    Betaflex is an asbestos-free, cellulose based paper with an NBR (Nitrile) binder, recogniseable by its dark grey/black colour. Betaflex and components cut from the material can be used in fibre jointing applications such as sealing and for electrical insulation.

    Fibre jointing materials like Betaflex are constructed from fibre strands held together with a resin, creating a strong and compressible material, which can be cut into intricately shaped gaskets, as well as pads, washers and strips which are placed between two surfaces to create a seal, cushioning or insulation. Most people automatically choose sponge or rubber when looking for a compressible material for gasketing applications, however ‘fibre’ based materials like Betaflex could also be considered.

    Why Use Betaflex Fibre Jointing Gaskets?

    Gaskets are an important component in almost all industries whether it’s for cushioning, sealing, insulating or gap-filling. Making the right material choice when designing such gaskets has become crucial especially where they need to ensure harmful chemicals and emissions are kept contained as Health & Safety regulations are tightened.

    Betaflex Fibre Jointing is a high quality material offering low compressibility and good elastic recovery, with sheets of material often being used in the production of gaskets for use within industrial sectors where there is a risk of exposure to or the need to seal against the leakage of oils, petrols, diesel fuel, water, antifreezes etc which would cause other materials to degrade and breakdown, resulting in gasket failure.

    Betaflex gaskets can often be found as seals for use where there is high volume fluid flow, such within plumbing, industrial pumps or as automotive transmission seals.

    The Benefits of Using Betaflex Fibre Jointing

    • Can be machined into a range of components
    • Low compressibility
    • Excellent electrical insulating properties
    • Resistance to oil, petrol, fuel, water, antifreezes, etc
    • Short term operating Temperature up to 180°C

    Other Grades of Fibre Jointing Available:

    When choosing ASG for your fibre jointing applications, you are sure to be offered a number of material options, thanks to our network of material manufacturers and suppliers - some of our other popular materials include:

    Ceramic Fibre material is constructed using ceramic fibres and an organic binder, designed for extreme temperature applications reaching up to 1250℃. Ceramic fibre pads have excellent strength and flexibility, excellent insulating properties and thermal resistance.

    Gasket Paper pads have a high resistance to petrol, oil and water, therefore often utilised within automotive applications (within fuel/oil pumps and filters). It is not recommended for industrial use due to its lack of resistance to chemicals and heat.

    Graphite foil is available in a number of grades, and is an excellent sealing material suitable for high temperature and high pressure liquid, steam, gas and chemical transfers. Graphite foil pads can be used where there is exposure to oil, petrol and gas - even nuclear or power generation applications.

    Millboard is made using a material composed of ceramic fibres, clay, insert fillers and binders. Although these padss can not be used with direct flame, they can handle temperatures of up to 1037℃.

    Non-asbestos fibre - Non-asbestos fibre has been designed to not only replace the original ‘Asbestos’ material, but also to be a more superior product with countless desirable properties as the material is manufactured in various formulations, each giving a combination of properties suited for different applications. Non-asbestos fibre can be blended with nitrile, thus giving fuel and oil resistance properties, with EPDM to create a potable water safe product or with PTFE for chemical resistance, they can also be supplied with a graphite coating to give steam and non-stick resistance properties.

    Presspahn is manufactured using kraft wood pulp, giving its distinctive ‘buff brown’ colour. Presspahn pads have excellent physical and mechanical properties, generally used as electrical insulation.

    Vulcanised fibre material is laminated plastic composed of only cellulose, with great mechanical strength and conformability. Vulcanised fibre gaskets can work in temperatures up to 110 ℃ anything more will result in the material fibres burning or breaking down.

    Advantages Of Using Betaflex Fibre Jointing Gaskets

    Using Betaflex fibre jointing gaskets offers users a number of desirable properties and advantages. Betaflex can be used within applications where temperatures reach up to 180°C (short term) and are suitable for sealing within industrial applications where there is exposure to or risk of leakage of oils, petrols, diesel fuel, water, antifreezes, etc.

    Betaflex fibre jointing gaskets can also be used for electrical insulation applications where they restrict the flow of electric current, ensuring the health & safety of users and people around the appliance. Betaflex fibre jointing materials can not only be supplied as converted finished components, but also as full rolls or sheets, giving customers the option and flexibility of being able to cut their own parts as and when required.
