Improved thermal insulation paper
Description
Superwool®XTRA Paper is made of Superwool®XTRA bulk fibres and organic binders. Superwool®XTRA paper is speciallyprocessed to offer excellent performance in high-temperatureapplications.
Superwool®XTRA paper provides stability and resistance to chemicalattack and is unaffected by incidental spills of oil or water. Thermal andphysical properties are restored after drying. It has excellent thermal insulation characteristics and exceptional handling properties.
Very flexible and resistant to tearing, Superwool®XTRA Paper is particularly suited to all applications requiring further processing (laminated composites, die-cutting, rolling, folding).
The organic binder burns out cleanly on the first firing at approximately300°C (572°F), with ignition starting at 180°C (356°F).TypePaper manufactured from high temperature insulation wool.
Classification temperature
1400°C (EN 1094-1) 2600°F (ASTM C892-17)
The maximum continuous use temperature depends on the application.
Melting point
Superwool®XTRA has a melting point of 1650°C (3000°F).
