Non-Asbestos Fibre

Compressed sheet fibre jointing is designed for a wide range of industrial and original equipment applications where sealing performance and specification are essential. Reinforced fibres blended with elastomeric binders and inorganic fillers are what allows the Novus materials to offer outstanding performance in a range of industrial applications, including:

  • Chemical processing
  • Aerospace
  • Automotive
  • Water

The sheets are manufactured using the calendaring process, in which a mixture of fibres, filler and binders is compressed between two rollers under loads. A variety of these components can be formulated using this process and so materials can be designed to function over an extensive range of fluids, pressures and temperatures.

The suitability of compressed fibre sheet grade in a given application is dependent on a number of factors, including:

  • Chemical resistance
  • Temperature
  • Pressure capability

To assist our customers in making informed choices regarding the suitability of a product for a particular application, these materials are subjected to a range of tests specified by statutory regulations and customer requirements.

  • BS 7531 is a key approval standard, providing a method for selecting compressed fibre grades based on performance characteristics
  • A material that meets the requirements of BS 7531 can be considered high quality, high-performance materials
  • BS 7531 defines two standards for materials: Grade X and Grade Y
  • Grade X is the higher specification and requires the material to meet a range of property criteria, allowing the material to be used in high temperature and other demanding applications
  • Grade Y also defines a range of property criteria, but the requirements are less demanding than those of Grade X
Graphite

Flexible graphite materials are universal sealing products consisting of pure carbon. The crystalline structure has been considerably expanded through a special chemical and thermal procedure.

The expanded crystals are formed into foil by a multi-stage calendaring process. The thin flexible graphite foil can then be laminated into thicker sheets to manufacture a range of sealing products.

This process can also be used for other forms, such as packing sets. Graphite has outstanding resistance to both high and low temperatures and is chemically resistant to most media. Thanks to its high compressibility and unlimited storage life, graphite is ideal for numerous applications.

PTFE

Polyterafluoroethylele (PTFE) is almost chemically inert, being attacked only under extreme conditions. For example, molten alkali metals, certain fluorine compounds at elevated temperatures and nuclear radiation.

In this respect, PTFE is useful as a gasket material, unfortunately, the material has a tendency to creep under load and has limited use in such applications. Modified PTFE materials include the benefits of PTFE and allow them to be utilised at higher compressive load and higher temperatures.

PTFE can also be used as an envelope to more conventional compressed fibre gasket material insert. This combines the chemical resistance from PTFE with the stress retention and recovery properties of the insert.

Semi-Metallic/Metallic

Spiral Wound Gaskets

Spiral Wound Gaskets consist of a ‘V’ shaped metal strip, which is spirally wound together with a soft filler material, normally graphite, PTFE or Hi-Temp.

The metal strip provides outstanding recovery whilst the flexible filler ensures excellent sealing. Defending on the application, the gasket can be specified with outer and/or inner rings.

Kamprofile Gaskets

Kamprofile Gaskets are made up of a metal core, usually stainless steel, with concentric grooves on either side. A sealing layer is normally be applied to both faces and depending on the service material, the layer can be graphite, PTFE, Novus Sheet material or metal (aluminium or silver).

Kamprofile Gaskets are ideal for both standard pipe and heat exchanger applications.

Corrugated Gaskets

Corrugated Metal Gaskets consist of a corrugated metal core, normally stainless steel, with a soft facing layer applied per face. The corrugations are there to provide resilience and reduce the dealing surface area, whilst the soft layer ensures outstanding sealing, even at low loads.

Corrugated Gaskets are particularly suited to being a replacement for metal-jacketed gaskets.

Metal-Jacketed Gaskets

Metal-Jacketed Gaskets consist of soft filler material, encapsulated in a metallic material. The filler material provides the gasket with compressibility and resilience, while the jacket provides compressive strength and blow-out resistance.
