These products are made from chamotte and refractory clays.
Their high-temperature firing gives them excellent refractory properties (refractoriness under load and creep) as well as improved overall characteristics.
These characteristics help them perform in more severe environments (aluminium industry, cement works, calcination and incineration) while maintaining a competitive quality / price ratio.
