Bulk Fibre provides stability and resistance to chemical attack. Exceptions include hydrofluoric acid, phosphoric acid and strong alkalies (i.e. NaOH, KOH). Bulk Fibre is unaf­fected by incidental spills of oil or water. Thermal and phys­ical properties are restored after drying.

Although Bulk Fibre's basic fiber form offers an economical alternative for most applications, they can be engineered to meet the requirements of your most demanding application. Fiber diameter, shot content, fiber length and form can be altered as required to achieve desired properties for specific applications.

BTU-BLOCK products are a family of microporous insulation designed for use in high temperature industrial applications. Microporous insulation is a very high thermal efficiency mate­rial which has a thermal conductivity less than that of still air. These materials, consisting of fine diameter heat resistant particles, reinforcement fibers, and high temperature radiation blockers, address the primary modes of heat transfer in a novel way compared to traditional refractories. These compo­nents are appropriately sized and configured to create a microporous structure. This structure limits the number and movements of air particles, and creates a material of excep­tionally low thermal conductivity. At elevated temperatures, the radiation blockers are employed to minimize radiation heat transfer by again proper sizing and distribution.

Microporous materials offer benefits in industrial applications including:

Minimizing heat loss relates simply to energy saving, or reheat issues. For example, steel ladles containing back-up microporous insulation  have substantially  less solidified steel remaining in the ladle after the casting process is com­plete, which requires reheating.

Consistency of operating temperatures, which results in a more consistent final product or an easier process to reg­ulate and control.

Minimum space requirements for an equivalent tempera­ ture drop across the insulation component, microporous material may need as little as 1A the thickness compared to traditional fibrous material (at elevated temperatures). BTU-Block Board can be field fabricated to shape or supplied from Thermal Ceramics in intricate shapes or custom sized boards.
