Betaflex Fibre Jointing

Here at Advanced Seals & Gaskets Ltd we supply and convert a multitude of materials including many plastics, foams, rubber, cork, sponge and papers, many of which can be used in very specialist sealing, electrical insulating or gasketing applications.

One such group of products offered from our vast catalogue are made using various types of fibre jointing, which includes betaflex fibre jointing or Betaflex 69. Betaflex fibre jointing can be manufactured in continuous rolls 1100mm wide and in various thicknesses from 0.25mm, 0.4mm, 0.5mm, 0.8mm up to 1.6mm.

Our onsite conversion facilities which consists of various saws, presses and slitters, allows us to take Betaflex materials and convert them into finished parts including pads, washers, gaskets or strips - all of which can be supplied laminated with a choice of our many self-adhesives.

    What Is Betaflex Fibre Jointing?

    Betaflex is an asbestos-free cellulose based paper with an NBR binder, recognised by its dark grey/black colour, used in fibre jointing applications for electrical insulation- restricting the flow of electric current, by supporting electrical conductors - without allowing the current to pass through. Fibre jointing materials like Betaflex are made up of fibre strands held together with a resin, creating a strong and compressible material, which can be supplied in pre-cut finished parts or taken in roll form as they give the customer and end-user the flexibility to be able to cut their own sheets, strips, gaskets, washers, etc out as and when they are required.

    Why Use Betaflex Fibre Jointing?

    Using the right type of gaskets and sealing materials has become crucial for many industries to ensure harmful chemicals and emissions are kept contained as Health & Safety rules are tightened.

    Betaflex Fibre Jointing is a high quality material offering low compressibility and good elastic recovery, often used in the production of seals or gaskets in industrial sectors where there is a risk of exposure to oils, petrols, diesel fuel, water, antifreezes etc and where there will be temperatures of up to 180°C for short periods of time.

    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

    Using Betaflex fibre jointing materials offer a number of advantages to users, Betaflex can be used within temperatures of up to 180°C (short term), suitable for use industrial sectors and applications where there is a risk of exposure to oils, petrols, diesel fuel, water, antifreezes, etc.

    Betaflex fibre jointing components can be used for electrical insulation applications where they restrict the flow of electric current, by supporting electrical conductors - without allowing the current to pass through, crucial when ensuring the health & safety of users and people around the appliance. Betaflex fibre jointing materials are manufactured in form, given customers the option and flexibility of taking the material in full rolls lengths, cut sheet or converted cut finished parts.
