Honeycomb Ceramic Monolith for RTO
Product Introduction
Cordierite is magnesium aluminum silicate material, which has very low linear expansion, low coefficient of thermal expansion and excellent thermal shock resistance. Cordierite also has excellent mechanical strength, porosity standards, and excellent performance in cost-effective extrusion and dry pressing forms.
Cordierite honeycomb is divided into two types: porous and compact.
