Fibre Jointing

Fibre Jointing Sheet

ASG offers a wide range of non-metallic sheet materials, thanks to a broad network of suppliers and material manufacturers, some of which are designed to meet the requirements of specific applications. One such range of products on offer from our extensive catalogue are fibre jointing sheets, which consists of a varied choice of material types each with its own unique properties to meet particular application demands and environments. Each material type is manufactured in various sheet sizes and thicknesses as standard, however as we carry out all our conversion in-house, we can cut these down to smaller sheets or in some cases supply the material in roll form (where available). Many of the sheets supplied by ASG  can be supplied either plain or laminated with one of our many self-adhesives, foils or with other materials to create composite sheets.


What is Fibre Jointing Sheet? 

Materials are often taken in sheet form as they give the customer and end-user the flexibility to be able to cut their own strips, gaskets, washers, etc out as and when they are required. Most people will instantly choose sponge or rubber when looking for a compressible material for sealing and gasketing applications, however in many cases, a ‘fibre’ based material could also be an option. Fibre jointing material is made of fibre strands held together with a resin, different fibres can be used to determine the gaskets compressibility, temperature range and strength.


Why use Fibre Jointing Sheets? 

With a raised awareness of environmental and health & safety issues, using the right type of gaskets and sealing materials has become crucial for many industries to ensure harmful chemicals and emissions are kept contained.  Fibre jointing materials are manufactured in a variety of types, using different fibre and binder compositions in order to meet an array of temperature, compression, insulating and chemical resistance properties.    Fibre jointing sheets generally have excellent resistance to chemicals and oils together with a high-temperature range and tensile strength, making them suitable for many industries.


Different Grades

When choosing Advanced Seals & Gaskets Ltd for your sheet materials, you are sure to be offered a number of options, each type of fibre jointing gasket have its own range of properties, colours, thicknesses, etc – our most popular include:

Betaflex is a cellulose-based fibre material, which is made using a nitrile binder giving it excellent tensile strength,  low compressibility, good elastic recovery and erosion resistance. Betaflex is used widely in the industrial and automotive sectors due to its resistance to oils. petrol, diesel and even antifreeze.

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

Gasket Paper has 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 gaskets can be used where there is exposure to oil, petrol and gas – even nuclear or power generation applications.

Millboard sheets are made using a material composed of ceramic fibres, clay, inert fillers and binders. This material can handle temperatures of up to 1037℃, however can not be used with direct flame.

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 gaskets 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 sheets are brown coloured material manufactured using kraft wood pulp. Presspahn sheets 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 can work in temperatures up to 110 ℃ anything more will result in the material fibres burning or breaking down.


Benefits of Using Fibre Jointing Sheets

Advanced Seals & Gaskets Ltd offer fibre jointing sheets in a range of materials, thicknesses, colours and finishes. Each material will provide insulation within certain applications and suitable for various levels of protection required. Some of the materials listed above are available in variants that can offer additional properties such as flame retardancy and higher chemical or temperature resistance for use in the most extreme environments.
