Aramid Fibre Gaskets & Sheet

Compressed Fibre Sheet Jointing/Gasket Material (also know as Non-Asbestos Fibre Sheeting, CNAF etc.)

William Johnston & Company Limited have manufactured aramid fibre joints, seals and gaskets for over 25 years. One of the first manufactures in the UK to move away from asbestos as a core material, William Johnston & Company Limited continue to lead the way in innovation with aramid fibre sheet sealing technology.

What are aramid fibres?
Aramid fibres are man-made high-performance fibres, with molecules that are characterised by relatively rigid polymer chains. These molecules are linked by strong hydrogen bonds that transfer mechanical stress very efficiently, making it possible to use chains of relatively low molecular weight. The term “aramid” is short for “aromatic polyamide”. Aromatic polyamides were first applied commercially as meta-aramid fibres in the early 1960s, with para-aramid fibres being developed in the 1960s and 1970s.Aramid fibres share some general characteristics that distinguish them from other synthetic fibres:

• High strength
• Good resistance to abrasion
• Good resistance to organic solvents
• Non-conductive
• Low melting point
• Low flammability
• Good fabric integrity at elevated temperatures

When combined with an elastomeric binder they provide the basis of aramid fibre sheet jointing. William Johnston & Company Limited stock, convert and support aramid materials from:-
