Thermal Ceramics, a business of Morgan Advanced Materials, has pioneered the development of low biopersistent (LBP) Superwool® fibres replacing Refractory Ceramic Fibre (RCF) in many applications across the temperature range up to 1450°C (2642°F). 

Our newest, patented Alkaline-Earth-Silicate (AES) LBP fibre, Superwool Prime, features:

Superwool Prime is patent protected and will support the expansion of our LBP Fibre product portfolio in the 1300°C (2372°F) classification temperature space by delivering a differentiated solution to our customers delivering energy savings, improved efficiency, and benefits for safety of employees and processes.

Thermal Performance is 18% better

Compared to Superwool HT, the thermal conductivity of Superwool Prime Blanket at 1000°C (1832°F) for 128kg/m3 (8pcf) density is 18% better.

The advantage increases up to 31% for 96kg/m3 (6pcf) density blanket and becomes significantly larger at 1200°C (2192°F).
