Celcor® Standard Wall
Proven cordierite performance for automotive catalyst carriers
The Celcor® Standard Wall substrate is the cornerstone of automotive emissions control, featuring cordierite ceramic material with an extremely low coefficient of thermal expansion (CTE). This enables exceptional thermal shock resistance during rapid temperature cycling in catalyst light-off events. Available in 400 and 600 CPSI configurations, these substrates provide the geometric surface area necessary for optimal catalyst loading and conversion efficiency in both gasoline and diesel applications.
