GOODFELLOW is offering a new series of fiber-based insulating products it reports are safe to use and retain their properties even at elevated temperatures. The alkaline earth silicate Superwool® 607® HT occupies only minimal space as it provides superior insulation for melting and heating furnaces, ladles, and covers, and other uses in foundries and other industrial applications like glass and ceramics manufacturing, and petrochemical processing, and in civil construction.

Fiber-based insulation products typically have had health issues associated with their use, Goodfellow acknowledges. But, the Superwool 607 HT was developed to be a safe-to-use alternative material with low biopersistence, meaning that inhaled fibers are removed from the body by natural processes.

Superwool 607 HT has very low thermal conductivity, so it achieves significant energy savings in minimal amount of space; low shrinkage, which avoids hot spots; high classification temperature (1,300°C); good strength; and thermal stability.

Goodfellow supplies specialty materials for scientific and industrial uses, and specializes at supplying small quantities (a few grams to a few kilos) of metals and materials for research, prototype development and specialized manufacturing applications. Superwool is available through Goodfellow under license by its developer, Morgan Thermal Ceramics.
