Glass felt 1290

silicaneedle-punched non-wovenfor thermal insulation

Silica needle felt is a felt made of amorphous silica fibre mechanically bonded by a modern production method without the addition of binders. The base material of these felts is made up of high-quality silica fibres that give the product greater compactness, flexibility and resistance to the maximum operating temperature. The diameter of the fibres is over 6 micron and the length of the filaments is equal to 50 mm. Scentless, white in colour, non-inflammable, it is chemically stable and offers a good level of sound absorption. On request, the felt can be aluminiumized, aluminiumized and embossed, with adhesive, coupled with glass fabric, with adhesive, coupled with glass fabric and cut to specifications. Applications Nautical, naval and automotive industries for thermal insulation and sound-proofing, motorbike sector for mufflers and silencers, industrial use for thermal insulation, sound-proofing and for valves.
