Vulcanised Fibre Gaskets

When it comes to gaskets, ASG pride themselves on the ability to source and supply a wide selection gasketing materials, from a broad network of worldwide suppliers, some of which are needed for specialist applications.  One such range of products on offer from our vast catalogue are various types of fibre jointing gaskets, with one type being Vulcanised Fibre Jointing, sometimes also called Vulcanised Fibre or Red Fibre (as the red coloured fibre is most popular and readily available in comparison to the black or grey counterparts).  Vulcanised Fibre is manufactured in sheet form usually at 1 metre by 1 metre or 1 metre x 2 metre in size, in a standard range of thicknesses from 0.5mm to 3mm from which gaskets can be cut or pressed. 

Our Vulcanised Fibre gaskets are manufactured in-house, meaning we can manufacture bespoke items to match our customer samples or drawings, from a simple rectangular picture frame gasket, to more complex and intricate shapes with notches or bolt holes.  Whether it's a small sample batch or a multi-thousand run, we have a machine designed to quickly and accurately produce perfectly formed gaskets every time, these include a range of presses, CNC and kiss-cut machines.

    What are Vulcanised Fibre Jointing Gaskets?

    Vulcanised fibre is manufactured using a blend of fibrous materials which can include wood pulp, paper and cotton which are passed through a zinc-chloride solution or sulphuric acid and heat-treated,  which causes the fibres to partially dissolve and bond under compression without the need for any bonding agents, creating a tough, resilient material, which lightweight and stiffer than most thermoplastics, ideal for gasket production.

    Vulcanised Fibre jointing gaskets sometimes take the form of a strip or pad, but are generally an intricately cut shaped piece of material placed between two surfaces to create a low-pressure seal preventing the leakage of liquids or air and to seal against the intrusion of dust and debris

    Why use Vulcanised Fibre Jointing Gaskets?

    Vulcanised Fibre gaskets demonstrate excellent mechanical strength and stability, they are lighter in weight in comparison to aluminum and compared to many plastics, are more environmentally friendly to manufacture as the material contains fewer chemicals and artificial binding agents. 

    Vulcanized fibre materials can withstand exposure to a variety of chemical solvents, oils, and grease without degrading and work between the temperatures of  -40℃ to +100℃.  Available in commercial, electrical and even WRAS approved grades, Vulcanised Fibre sheets can be found used to create gaskets for use in water dispenser systems and even found within electrical motors, home appliances and hand tools.

    The Benefits of using Vulcanised Fibre Jointing Gaskets

    • Temperature range  of  -40℃-100℃
    • Resistant to chemical solvents, oils and grease
    • Available in commercial, Electrical and WRAS grades
    • high mechanical strength and dielectric properties
    • Excellent anti-static and ageing properties
    • Good resistance to wear, fatigue and impact

    What can be used as an alternative to Vulcanised Fibre?

    Elephantide -  a pressed paper, recognised by its blue colour as it’s manufactured using blue cotton, suitable for low voltage insulation to insulate electrically hot items.

    NOMEX - is a synthetic aromatic polyamide polymer that provides high levels of electrical, chemical and mechanical integrity over a wide range of temperatures. Nomex offers chemical resistance to acids, alkalis, solvents and radiation, can be used with oils, resins, adhesives, refrigerants and is self-extinguishing

    VALOX - a flame retardant film, tested to UL94 VTM-0 which has very high compressive and dielectric strengths, very low water absorption, excellent dimensional stability and good chemical resistance. As it doesn't contain plasticisers it will not become brittle with age under normal conditions.

    Advantages of using Vulcanised Fibre Gaskets?

    There are many advantages to using gaskets manufactured using Vulcanised Fibre materials, some of which include the material being manufactured in a more environmentally friendly way in comparison to most other materials and in return doesn’t expose users to as many chemicals and can be used in direct contact with metals without causing corrosion. 

    As Vulcanised Fibre is available in several grades, it is highly versatile in the number of applications it can be used, from seals or washers in taps to components in electrical equipment, it also offers resistance to chemical solvents, oils and grease exposure and is mechanically very strong so the gaskets will not break or tear during use or conversion - unless the max temperature is exceeded which may cause burns or if used in very wet or humid conditions. 

    Other advantages of using Vulcanised Fibre gaskets include it’s resistance to wear, fatigue and impact, so often used for abrasion resistance, it has a wide working temperature range of -40℃-100℃ and often utilised in machinery, railway and aerospace industries.
