Non-asbestos fibre materials replaced the use of asbestos gaskets following the ban in the 1990s on the use of the toxic material across industry. Asbestos gaskets were commonly used in engines and heavy industry applications, such as high-pressure steam systems, because of the material’s excellent heat-resistance properties.
Modern fibrous materials, such as those supplied by Klinger, Novus and Flexiseal, are commonly manufactured using aramid fibre (Kevlar) blended with polymers for different applications.
The comprehensive range of Klinger CNAF (compressed non-asbestos fibre) materials are designed for a multitude of high-temperature applications.
The Novus range of non-asbestos fibre materials are suitable for high-temperature operations where oils, fuels and acids are used.
The products in the Flexiseal product range comprise compressed fibres and rubber binders for resistance to fire, steam, hydrocarbons and chemicals.
A flexible gasket material that is easy to cut, Latty Gold has very good resistance to mechanical, thermal and chemical loads.
A range of highly proven non-asbestos rubber-bonded gasket materials made from aramid fibres and special fillers.
Garlock’s aramid-based compressed non-asbestos (CNA) fibre sheet materials provide excellent thermal stability in a range of applications.
We manufacture non-asbestos gaskets as new or as replacements for existing asbestos material gaskets to suit the requirements of the customer. We use CAD design to create precision gasket profiles and cutting-edge manufacturing equipment to guarantee the accuracy of the finished gaskets over large or short runs.
Our experienced team can help clients with materials specification and prototyping and we offer cost-effective manufacture for small volume runs. All gaskets are supplied to recognised national and international standards.
Non-asbestos fibres include aramid, Kevlar and fibreglass. Aramid is often used for its excellent heat resistance and strength. The natural material is up to five times stronger than steel and twice the strength of glass fibre or nylon. It is also resistance to absorption and organic solvents, has good chemical resistance and low flammability.
Non-asbestos gaskets typically use elastomers such as nitrile, neoprene, or EPDM rubber as the binder material, with each elastomer offering specific advantages. For example, aramid fibres with a nitrile binder are a good choice for applications such as water and wastewater treatment, oil and gas production, food processing, pipe flange gaskets, and boiler gaskets.
