ShreeCera Vacuum formed Ceramic Boards and Shapes are rigid products made from Ceramic Fiber which is mixed with organic and inorganic binders with or without mineral fillers. The key feature of this product is that it contains no asbestos element and high strength due to long resilient filament structure and binder system. This gives it very high insulating value, makes it resilient and chemical resistant.
