Superwool XTRA Paper is manufactured using our patented Superwool XTRA composition and technology. Superwool XTRA Paper, our newest innovation does not form respirable crystalline silica and is designed to offer excellent performance in demanding high temperature applications.
Superwool XTRA has excellent thermal and mechanical insulation properties and handleability is exceptional. Extreme flexiblility and high tensile makes Superwool XTRA Paper ideally suited to applications requiring further processing (laminated composites, die-cutting, rolling, folding as examples).
Superwool XTRA Paper provides stability and resistance to chemical attack and is unaffected by incidental spills of oil or water. Thermal and physical properties are restored after drying. An organic binder burns out cleanly at approximately 300°C (572°F) upon initial firing, with ignition starting at 180°C (356°F).
