1 Side 25mm Fiberglass Needle Mat Sewn with Silicone Coated Fabric
The general transition from asbestos to glass fibres has resulted in an increasingly wide range of applications for needle mat – a mechanically (rather than organically) bonded glass fibre insulating blanket.
A 100% fibreglass matt, the felt is manufactured in web form and mechanically needled together to form thicknesses of 6 mm, 12,5 mm and 25 mm. Long textile fibres have been accurately chopped to provide maximum density, high insulation and strong physical properties at temperatures up to 648ºC (1200ºF).
Needle mat is non-corrosive, non-combustible, non-alkaline and chemically stable. Its excellent heat resistance, flexibility and low thermal conductivity makes it an effective,
low-cost replacement for asbestos mats, millboard refractory paper and other similar products.
Needle mat products are being used for increasingly complex applications in oil refineries, steam and gas turbines, exhaust systems on diesel tugs, tankers, pleasure yachts, Coast Guard and Navy vessels.
They are used to relieve stress at welding points, on valve flange covers and for acoustic absorption applications. In addition, needled blankets act as insulators for automotive thermostatic switches, on floor pans over catalytic converters and in luggage compartments.
In nuclear power plants, these blankets reduce labour costs during removal for inspection and service, and reduce re-insulation costs associated with poor-fitting rigid block.
