Main refractory product used in the production of ceramic articles, Estiva batts are manufactured in cordierite and cordierite-mullite through the extrusion, slip casting and pressing processes.

Regardless of how they are made, our batts have excellent dimensional stability, high flexural strength under normal and application temperature, and excellent thermal shock resistance.

To maximize the useful space of ceramic load to be fired, our staff evaluates the conditions of use of each project to propose the best solution, seeking to reduce weight (refractory mass-inert), improving the firing cycles and reducing energy consumption.

Batts can be manufactured in a variety of shapes and geometries, such as: hollowed and solid, flat or ribbed, bore-gride or with special designs (such as cuts, grooves, etc.) to suit customer needs.
