Fibre Jointing Strip
ASG offers a wide range of cut non-metallic products, thanks to a network of suppliers and material manufacturers, some of which are needed for specific applications. One such range of products on offer from our vast catalogue are fibre jointing strips (or fibre sealing tape), which consists of a varied choice of material types each with its own unique properties to meet particular applications and levels of demand. Fibre jointing strips are all made to order, manufactured by our highly skilled workforce, using state of the art machinery including band saws, strippers, log cutters and even presses depending upon the size and quantity required – for very small strips in high volume runs, a kiss-cut option may also be available for faster production and time efficiency for the end-user. In-house production allows us to closely oversee the whole production process to ensure that we consistently produce high quality, competitively priced strips.
What is a Fibre Jointing Strip?
Strips are pieces of material often cut to a specific width and length as requested by our customers, in some cases available as continuous rolls/coils to be cut as when needed by the end-user, often used in a similar way to a gasket placed between two surfaces to create a seal, provide cushioning or insulation. 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 types of fibre can be used to determine the gaskets compressibility, temperature range and strength.
Why use Fibre Jointing Strips?
A raised awareness of environmental and safety issues means using the right types of 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 strips generally have excellent resistance to chemicals and oils together with a high-temperature range and tensile strength, making them suitable for many industries.
When choosing Advanced Seals & Gaskets Ltd for your sealing and insulation needs, you are sure to be offered a number of material choices, our most popular fibre jointing materials 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 strips are used widely in the industrial and automotive sectors due to their 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 strips have excellent strength and flexibility, excellent insulating properties and thermal resistance.
Gasket Paper strips 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 strips can be used where there is exposure to oil, petrol and gas – even nuclear or power generation applications.
Millboard strips are made using a material composed of ceramic fibres, clay, insert fillers and binders. Although these strips 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 strips 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 strips are manufactured using a brown coloured material manufactured using kraft wood pulp. Presspahn strips 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 strips can work in temperatures up to 110 ℃ anything more will result in the gasket fibres burning or breaking down.
Benefits of Using Fibre Jointing Strips
Advanced Seals & Gaskets Ltd offer fibre jointing strips in a range of materials, thicknesses and finishes, each material type providing resistances and insulation within certain applications and suitable for various levels of protection required, some of these benefits include resistance to high temperature and high-pressure liquid, steam, gas, chemicals, oils, petrol and diesel. They can also be used for electrical and thermal insulation applications. 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.
