Non-Asbestos Gasket Materials

non-asbestos gasket material

Non-Asbestos Fibre materials are so-called because they fill the gap in the range of gasket materials previously occupied by asbestos. Asbestos, although now known to be a dangerous material, had excellent heat resistance properties, which is why it was utilised so widely in high temperature applications. When asbestos was outlawed, replacement materials were needed; and so these asbestos-free, or non-asbestos, materials were developed to perform the same function, but without the corresponding danger to human health.

These materials are now commonly comprised of aramid fibre (Kevlar) and non-organic fibres, which are in turn blended with different polymers to meet different applications: most commonly nitrile rubber, for fuel and oil resistance. These materials can also be graphite coated for non-stick and steam resistance, mixed with PTFE for excellent chemical resistance, or with EPDM for potable water applications.

Common Industries Utilising Non-Asbestos Fibre

  • Oil and Gas
  • Chemical Processing
  • Petrochemical Industry
  • Process Industry

General Properties of Non-Asbestos Non-asbestos materials generally have very good heat resistant properties. They are also good for use in applications that put them into contact with water, petrol, or natural gas.

As such, non-asbestos materials are used in air compressors, diesel engines, pipelines, and many other general industrial and marine environments.

We stock Novus (Flexitallic) and Klinger and Garlock non-asbestos materials.

Is Non-Asbestos the Best Material for My Application? If you are unsure as to which material is best for your application then you can consult our guide to gasket materials. Material specifications can be downloaded here.

Alternatively, we are always happy to offer technical help and advice and so if you require assistance then please do not hesitate to contact us.

Certification & Traceability: Both certification and traceable certification can be supplied with your material, should it be required by you or your customer. Traceable certification lists the batch number and cure date/ manufacture date of the material. Please contact us to request certification at the time of order. Traceable certification cannot be retrospectively supplied on orders that have already been fulfilled.

We are ISO 9001 and ISO 14001 quality certified.
