Advanced Seals & Gaskets Ltd source materials of the highest quality from a network of reputable material suppliers, from across the world for use in specialist sealing, insulating and gasketing applications.
One such material is Betaflex, usually used in fibre jointing applications. This material is manufactured in continuous rolls 1100mm wide and in various thicknesses from 0.25mm, 0.4mm, 0.5mm, 0.8mm up to 1.6mm from which strips can be cut. Our state of the art onsite conversion facilities consists of various log cutter, presses and slitters, allowing us to take rolls or sheets of Betaflex material and convert them into finished cut betaflex fibre jointing strips in a choice of lengths and widths.
Log cutters and slitters are ideal where rolls or coils of strip or betaflex tapes are required, where the end users can cut off lengths to suit each individual application, small strips are generally produced using a press into individual pre-cut lengths or even kiss-cut on a roll for each of use and for very high volume runs - all of which can be supplied laminated with a choice of our many self-adhesives.

What Are Betaflex Fibre Jointing Strips?
Betaflex fibre jointing is an asbestos-free cellulose based paper made with an NBR binder, recogniseable by its dark grey/black colour. Betaflex and components cut from them are used in fibre jointing applications or electrical insulation- restricting the flow of electric current. Fibre jointing materials like Betaflex are constructed from fibre strands held together with a resin, creating a strong and compressible material.
Betaflex 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.
Why Use Betaflex Fibre Jointing Strips?
Using the right material when designing gaskets and seals has become crucial for many industries where they need to ensure harmful chemicals and emissions are kept contained or where there is a risk of fire caused by electricity as Health & Safety regulations are tightened.
Betaflex Fibre Jointing is a high quality material offering low compressibility and good elastic recovery, with strips of material often being used as sealing or gasketing components in industrial sectors where there is a risk of exposure to oils, petrols, diesel fuel, water, antifreezes etc which would cause reactions and damage to other materials, resulting in gasket failure, and where there will be temperatures of up to 180°C for short periods of time.
Betaflex strips can often be found used as seals where there is high volume fluid flow, as industrial pump gaskets or automotive transmission seals.
The Benefits of Using Betaflex Fibre Jointing Strips
- Can be machined into a range of sizes
- 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 Strips
Strips made using Betaflex fibre jointing offer a number of advantages to users. Betaflex strips can be used in applications where temperatures reach up to 180°C (short term) and are suitable for sealing within industrial sectors and applications where there is a risk of exposure to or risk of leaking oils, petrols, diesel fuel, water, antifreezes, etc.
Betaflex fibre jointing strips 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 are manufactured in roll form, giving customers the option and flexibility of taking the material in full rolls lengths to cut down themselves or in pre-cut finished parts ready to be used straight away.
