MaxWool 2300 High Temperature

MaxWool® 2300

Refractory Ceramic Fiber Blankets

MaxWool 2300 high-temperature insulating blankets are made from long strand spun, high purity ceramic fibers forming a strong, flexible needled product which provides superior insulation properties for usage at higher temperatures.

The strong needling of MaxWool ceramic blankets derive in a completely inorganic product with no binder resulting in smoke or flame.

MaxWool 2300 is rated to 2300°F (1260°C) and is available in a range of thicknesses and densities.
