Non-Asbestos Fibre Pads
Here at Advanced Seals & Gaskets, we can supply pads manufactured from a variety of materials including special types such as non-asbestos fibre, a material that was developed as a replacement for Asbestos itself which is considered a dangerous substance and illegal to use.
Non-asbestos fibre pads are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one-off samples to multiple batches runs.
Non-asbestos fibre pads can be supplied as loosely cut parts or kiss-cut on rolls for small pads where a high quantity is required or for use on fast-paced assembly lines. Pads are often taken for use with sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration. Non-asbestos fibre pads are preferred in applications where there is exposure to extreme heat, water, petrol and natural gases.
What are Non-Asbestos Fibre Pads?
Pads are often used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities. Non-asbestos fibre or CNAF (compressed non-asbestos fibre) is just one of many fibre jointing materials on offer, from which we are able to produce pads.
Non-asbestos materials are produced using fibre and carbon, then bonded with a rubber (polymer) agent, each formulated to meet the needs of different applications. Non- asbestos fibre pads are cut from sheets in thicknesses ranging from 0.25mm up to 4mm and supplied as squares or rectangles with the option of radius corners, and also as circular or oval-shaped pads or ‘discs’.

ASG takes great pride in producing high-quality pads from a wide range of materials such as EPDM, neoprene, PVC, cork, acoustic foam, solid rubber, polyethylene, polyurethane to name a few. Onsite production enables us to produce bespoke pads, within a minimal lead time whilst remaining cost-effective. Please get in touch with our team for further information on the many materials we offer.
Why use Non-Asbestos Fibre Pads?
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.
The material used to manufacture non-asbestos fibre pad 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.
Non-asbestos fibre pads can be commonly found within high-pressure applications such as compression chambers, air compressors, marine environments, diesel engines and in oil, gas, chemical and fuel processing industries.
Benefits of Non-Asbestos Fibre Pads
- Water/steam resistance (selected grades)
- Chemical Resistant
- Fuel Resistant
- Impermeable To Gas
- Available in a range of grades
- Excellent Seal
Advantages of Using Non-Abestos Fibre Pads
The various grades of non-asbestos fibre materials come with countless advantages and properties that are ideal for many industries. Non-asbestos fibre pads are preferred in applications where there is exposure to extreme heat, water, petrol and natural gases.
Non-asbestos pads can be supplied in specifically cut shapes, easily produced using one of our many presses, kiss-cut machines and even our oscillating knife for larger/thicker gaskets, all available plain or coated with one of many self-adhesives.
Advanced Seals & Gaskets work with a number of material manufacturers, meaning our customers benefit from more choice, 2 of the most popular types are detailed below.
Novus is a compressed non-asbestos fibre-based material, usually manufactured with a polymer binder rubber, which has excellent sealing abilities. This material is ideal for a number of general-purpose applications, displaying a great resistance to the majority of fuels, oils and acids. Within the Novus non-asbestos fibre material, pads can be produced in a choice of grades, each can be identified by its colour. Each grade of Novus is manufactured using a different combination of fibres and binders to give a set of unique properties, levels of resistance and working temperature ranges.
**the temperatures given are to be used as a guide only - as this can vary depending on factors such as the material thickness and pressure levels**
Novus 10 is a black material consisting of carbon fibre and nitrile rubber. It has a maximum operating temperature of 435°C, with good steam and creep resistance, suitable for use oils, fuels and refrigerants.
Novus, a yellow material consisting of aramid fibres and nitrile rubber. It has a maximum operating temperature of 400°C, with good resistance to general chemicals, steam, oil, fuel and gas. It has excellent water (hot and cold) resistance and is WRAS approved for potable water applications.
Novus 26 is a green material made up of aramid fibres and natural rubber. This grade has an operating temperature of 300°C, with good swell control when exposed to oil and is resistant to water, ideal for automotive applications.
Novus 30 is orange in colour, consisting of both aramid fibres and inorganic, with a nitrile rubber binder. It has a maximum operating temperature of 400°C, with good all-round resistance to water, steam, oil, fuel, chemicals and gas.
Novus 34 is manufactured white in colour, using a combination of aramid fibres, inorganic fibres, special additives and nitrile rubber. This grade has a maximum working temperature of 450°C, with good resistance to gases, solvents, oils and high-pressure steam.
Novus 45 is a blue material containing recycled synthetic fibre jointing and nitrile rubber. Novus 45 has a maximum operating temperature of 300°C, with good resistance to milder chemicals, low-pressure steam, fuel and oil.
Klinger is another popular non-asbestos fibre material from which ASG can cut and supply pads. Klinger is manufactured in a variety of grades each suited for a range of environments and applications, each grade is produced using a combination of materials chosen to produce a product with various high-level resistances and a range of maximum working temperatures. Generally, pads manufactured using Klinger will have good resistance to water, petrol, oils, solvents, gases, steam and some acids/alkalis. Klinger materials can often be found in sealing applications within oil, gas, petrochemical, power generation and aerospace industries.
