Cervac Board

Cervac products are a family of rigid, high-strenth ceramic fiber boards manufactured in a wet vacuum forming process using Fiberfrax Refractory Ceramic Fiber (RCF), organic & inorganic binders. All Board products offer low thermal conductivity, high temperature stability, excellent resistance to thermal shock and chemical attack.

The Cervac board family exhibits excellent chemical stability, resisting attack by most corrosive gases. Exceptions are hydrofluoric, phosphoric, hydrochloric and sulfuric acids as well as concentrated alkalies. Not recommended for applications involving direct melton metal or liquied contact. Aluminium & Water Repellant variations also available. Variation Grades, Densities, Strength, Shapes & Sizes are available & can be manufactured as per requirment.
