Fibermesh-450 achieves four zero Early Fire Hazard Indices when tested in accordance with AS 1530:Part 3-1976 (same as BS 476 : Part 5, 6, 7-1967) for non-combustible material.
Exposure to an atmosphere of 50 C and 95% relative humidity for 96 hours results in moisture absorption of less than 0.2% by volume. Should insulation become wet, full thermal efficiency will be restored on drying out.
Water repellent grade according to BS 2792 section 12 is available to order.
Fibermesh-450 is faintly alkaline and is incapable of corroding steel, copper, or aluminium. To maintain this condition, protection must be provided against contamination from external sources. When tested in accordance with BS 3958:Part 5-1969,results in range of pH 7.5-8.0. Fibermesh-450 contains less than 15ppm soluble chlorides which minimize the risk of external stress corrosion cracking in austenitic stainless steel. Stainless mesh may be specially ordered for applications where galvanized mesh is not suitable.
Fibermesh-450 blanket is designed for maximum flexibility. It will essentially retain its thickness, while conforming to virtually any irregular shape.
Retention of the fibres by the wire mesh prevents any cracking or breaking.
Because the fibres in Fibermesh-450 are stitched to the wire mesh, the blanket is especially resistant to fall out under conditions where vibration is present.
Fibermesh-450 is particularly useful in situations involving both vibration and high temperatures where standard bonded insulation materials are less resistant to the effects of vibration.
Fibermesh-450 is designed particularly for flexibility. It does however have reasonable resistance to compression when subjected to normal compressive load.
