Ceramic
Substrates
& Filters
Industry-leading ceramic catalyst substrates and diesel particulate filters engineered for the most demanding global emissions standards — Euro 6d, EPA Tier 3, China 6, and beyond.
Product Portfolio
Two Core Product Lines
From catalyst carriers to wall-flow particulate filters, our portfolio covers the full emissions control spectrum.
Ceramic Substrates
Celcor® Family — 4 Products
Cordierite honeycomb catalyst carriers in Standard Wall, Thin Wall, Ultra-Thin Wall, and Large Frontal Area configurations. From 200 to 900 CPSI — optimized for every gasoline and diesel application.
Particulate Filters
DuraTrap® Family — 4 Products
Aluminum titanate and cordierite wall-flow filters for diesel and gasoline PM capture. AT LP, AT HP, Heavy Duty, and GC gasoline variants covering all vehicle classes.
Core Technology
Engineered at the
Cellular Level
Our honeycomb ceramic architecture maximizes geometric surface area while maintaining structural integrity across extreme thermal cycles. Every parameter — cell density, wall thickness, porosity — is optimized for your specific application.
Cordierite & Aluminum Titanate
Ultra-low CTE materials engineered for extreme thermal shock resistance across rapid temperature cycles.
Precision Cell Geometry
Wall extrusion precision to ±0.01 mm enables consistent cell density from 200 to 900 CPSI.
Asymmetric Cell Technology (ACT)
Inlet cells larger than outlet cells optimize soot capacity and pressure drop for catalyzed filter systems.
