NASB Mica: This consists of Mica flake bonded with silicone resin which is then reinforced with specially tanged stainless steel. This material is used in hot dry gas applications and is suitable for temperatures up to 1000 DegC.
Graphite: Available with or without steel tang. This material has excellent chemical resistance along with good sealing and load bearing properties. Suitable for temperatures up to 500 DegC.
NASB7Y: Made to specification, BS7531 GRADE Y (DIN28091 FA-AM1-0). High quality compressed non asbestos fibre jointing sheets based on aramide and special mineral fibers mixed in a NBR rubber matrix. This material offers high stress relaxation (BS7531 Grade Y, DIN28091 FA-AM1-0), high compressibility and low gas permeability, excellent characteristics for universal services. Material suitable for use with air, water, oils, hydrocarbons, gases and common uses. Particularly suitable for use in compressors, pumps, valves and OEM equipment.
NASB8XG: Made to specification, BS7531 GRADE X (DIN28091 FA-AM1-0). High quality compressed non asbestos fibre jointing sheet made with aramide and high quality mineral fibres in a NBR rubber matrix. NASB8X has the lowest gas permeability value, with the highest tensile strength and the best flexibility. NASB8X is a high-tech product with the highest stress relaxation value (BS7531 Grade X, DIN28091 FA-AM1-0) in the market. Material suitable for many uses and most fluids. Graphite coated both sides.
NASB3: Manufactured from recycled aramid fibre jointing materials, including organic and inorganic synthetic fibres. This material can be used in a variety of applications as a competitive substitute for traditional compressed asbestos-free materials for joints in less demanding applications.
NASB5: This comprises both aramid and inorganic fibres, mixed with a blend of elastomers to give excellent resistance to many chemicals at elevated temperatures. The material is suitable for most medium range applications and can be used with oils, solvents, alkalis and organic acids (not Nitric or Hydrofluoric). It is also produced as NASB5G – graphite finish and NASB5MG – wire reinforced.
NASB6: Nasb6 is produced from a mixture of aramid and high quality mineral fibres bonded with a rubber NB and SBR matrix resulting in a material with exceptional flexibility and cutting properties. It’s controlled swelling in oils makes it’s a suitable choice for the Automotive and Industrial Machinery industries. In tests with major engine manufacturers it is far surpassing other materials in it’s band. Nasb6MG is also available, having a wire reinforcement layer, ideal for higher pressure or vibration areas.
NASB9: Manufactured from aramid and high quality mineral fibres mixed with a rubber NBR matrix. This material has high compressibility, good resistance to traction and low gas permeability which are excellent characteristics for many industrial applications, where high demand for resistance to temperature and pressure must be combined. Again Nasb9MG is produced with wire reinforcement.
NASB10: Similar to Nasb9, but with modified ingredients to give a highly robust jointing material which has been approved to the UK’s WRAS (Water Regulations Advisory Scheme) BS6920 – registration number 9903523.
NASB12: This is a premium grade non-asbestos sheeting, produced from carbon fibre and Nitrile rubber binder. It is suitable for steam up to 290°C and has excellent resistance to most chemicals. The material is recommended for use with oils, fuels, hydrocarbons, alkalis and refrigerants.
