Honeycomb Ceramic Substrate
Cordierite honeycomb monolith with extremely low thermal expansion, high specific surface area and rapid light-off, used as the carrier medium for oxidation and reduction catalyst.




Honeycomb Ceramic Substrate
Product Overview
PRUITING® advanced honeycomb substrate is made from cordierite material and can be used at temperature up to 1350 °C. Because of its nature of crystallization, crystal-chemical formula cordierite has extremely low coefficient of thermal expansion. High specific surface area, low pressure drop, rapid light-off time and reliable & durable performance are achieved through high cell density of 400 and 600 CPSI.
Honeycomb-like structure with thousands of parallel channels forces exhaust gases into the turbulent flow regime resulting in better contact between emission and precious metal, enhanced mass-transfer conditions, and higher conversion efficiency.
All of these make our ceramic honeycomb an ideal catalyst substrate media for oxidation & reduction catalyst. Current, our typical substrate are available in a variety of sizes with the different shapes, such as: round, elliptical, race track and so on.
