MaxWool 3000 High Temperature

MaxWool® 3000

Polycrystalline Wool Blankets

MaxWool 3000 is a high-temperature insulation blanket produced from polycrystalline fibers that are needled for strength, providing a product that has exceptional performance at very high temperatures. MaxWool 3000 exhibits almost no shrinkage and excellent insulating properties up to its rated maximum use temperature of 3000°F (1650°C). Produced with a mullite chemistry (72% Al₂O₃; 28% SiO₂), MaxWool 3000 is thermally stable at elevated temperatures, and should be considered for use in applications above the temperature rating of ceramic fiber blankets.
