Manufacturing Processes:Extrusion molding, high-temperature sintering, CNC cutting, surface finishing, and optional precious metal catalyst loading. Features:High thermal stability, uniform cell structure , low pressure drop, customizable diameter/length/CPSI. Customization:Cell density (100–600 CPSI), size (Ø50–Ø200mm), material (cordierite, SiC), coating options (Pt/Pd/Rh), and private label packaging. | |||||||||
Product Introduction
The ceramic catalyst substrate is the functional core of automotive emission control devices such as catalytic converters, DPFs, and GPFs. It features a honeycomb monolith structure with thousands of small square or hexagonal channels, which allow exhaust gases to pass through while providing a large surface area for catalytic reactions or particulate filtration.
Made primarily from cordierite or silicon carbide, these substrates are engineered for high thermal resistance, low thermal expansion, and structural integrity under high-load conditions. Their surface is often coated with precious metal catalysts (platinum, palladium, rhodium) depending on the emission standards to be met.
This substrate supports the efficient conversion of CO, HC, and NOx in gasoline vehicles, as well as particulate matter filtration in diesel and direct-injection engines. Its precision structure also ensures minimal backpressure, allowing for stable engine operation.
Features & Benefits
The honeycomb ceramic structure delivers excellent mechanical strength, uniform flow distribution, and high cell density options ranging from 100 CPSI to 600 CPSI (cells per square inch). It ensures optimal catalytic efficiency while minimizing pressure drop across the exhaust system.
OEMs and converter manufacturers can benefit from the modular size options and reliable performance in mass production. Whether for Euro 6, EPA Tier 3, or China VI compliance, this substrate forms the foundation of certified emission systems.

FAQs
Q1: What's the difference between cordierite and SiC substrates?
Cordierite is more cost-effective and ideal for gasoline vehicles. SiC is preferred for diesel systems due to higher thermal resistance and particulate filtration efficiency.
Q2: Are these substrates suitable for Euro 6 or EPA use?
Absolutely. They are designed for compliance with the latest emission standards when integrated with certified catalyst formulations.
Q3: Can I request private labeling or custom packaging?
Yes. We support OEM/ODM cooperation with logo printing, carton design, and pallet packaging for bulk export.
