Refractory felt SUPERWOOL 607 HT FELT

Price: on request

Superwool HT Felt is an insulating felt, obtained by hot pressing. It is made from Superwool HT fibres, bonded with an organic binder which begins to burn out at 180°C. This special binder makes Superwool HT Felt particularly suitable for die-cutting operations. Semi rigid, it is neither brittle nor dusty. Superwool HT Felt optimises the manufacture of complex, die-cut shapes to close tolerances. Made from chemically stable fibres, lightweight and very insulating, Superwool HT Felt is a multi-purpose product.

felt manufactured from high temperature insulation wool.

Classification temperature:
1300 0C (ENV 1094-3)

The maximum continuous use temperature depends on the application. Unaffected by most chemicals except strong alkalis, phosphoric acid and molybdenum. For further advise please contact your local Morgan Thermal Ceramics partner.
