EURO 6 Honeycomb Ceramic Catalyst Passenger Car
Product Description
What Are Honeycomb Ceramics?
Honeycomb ceramics are advanced porous industrial ceramic materials featuring a unique multi-channel structure that delivers:
✔ Ultra-low thermal expansion – Maintains structural integrity under extreme temperatures
✔ High porosity (400-600 CPSI) – Maximizes surface area for optimal exhaust gas treatment
✔ Exceptional thermal shock resistance – Withstands rapid temperature fluctuations
Why Choose Ceramic Substrates for Automotive Catalysts?
Specially engineered for automotive exhaust emission control, our honeycomb ceramic carriers provide:
• Superior mechanical strength – Resists vibration and mechanical stress
• Long-term high-temperature stability – Reliable performance in 800-1000°C environments
• Low backpressure design – Improves engine efficiency while reducing emissions
Premium Material Composition
Our substrates are manufactured from:
• Cordierite (2MgO•2Al2O3•5SiO2) – Industry-standard material with near-zero thermal expansion
• Mullite & Aluminum Titanate – Enhanced thermal durability for extreme conditions
• High-purity talc, kaolin & alumina – Ensures consistent quality and performance
Manufacturing Excellence
Precision-engineered through:
1. Advanced extrusion molding – Creates uniform honeycomb channels
2. Strict sintering process – Guarantees structural stability
3. Quality-controlled coating – Ready for precious metal catalyst loading (Pd, Pt, Rh)
