Aluminised Silica Sleeve will reflect up to 95% of heat, with no organic flame contribution and provides a tough, impermeable, heat reflective coating that allows the silica fabric to be used in a variety of demanding applications Aluminized Silica Sleeve is specifically designed for protective apparel and shields used in environments that pose serious fire risk or safety hazards associated with hot works or radiant heat sources. The base silica fabric will supporting continuous operating temperatures of 2300°F (1260°C) with peak temperatures to 3000°F (1650°C). Although the aluminum layer is considered to be sacrificial at temperatures above 600°C the aluminum will withstand continuous operating temperatures in the 315°C range with no significant degradation. However, long term exposure at temperatures above 315°c will ultimately degrade the adhesive used to laminate the aluminum to the cloth substrate.
