Cordierite DPF

Cordierite DPFs provide an excellent filtration efficiency about 95%, effectively capturing diesel particulate matter to help to meet stringent emission standards.

Cordierite DPFs have a low coefficient of thermal expansion(CTE) ≤1.2×10-6 / °C, which makes them highly resistant to thermal shock. This property allows the DPF to withstand rapid changes in temperature during regeneration, ensuring durability and reliable performance.

Cordierite DPFs are more economical to manufacture compared to other materials such as silicon carbide. This cost advantage translates to a more affordable product without sacrificing performance, making it a budget-friendly choice for your business.

Honeycomb ceramic cordierite DPFs have a lower density (0.6-0.8 g/cm3) compared to other DPF materials, resulting in a lighter product. This weight reduction can contribute to improved fuel efficiency and overall vehicle performance.

Cordierite DPFs typically require a lower regeneration temperature (500-600°C) compared to other materials. This property can lead to lower fuel consumption and reduced emissions during the regeneration process

Silicon carbide DPFs offer outstanding filtration efficiency, typically ranging from 96-98%. This high level of performance effectively captures diesel particulate matter

With a mechanical strength, silicon carbide DPFs are more resistant to vibrations and impact compared to other materials like cordierite. This increased durability ensures reliable performance under various operating conditions.

Silicon carbide DPFs have a thermal conductivity of 20-25 W/m·K, which is significantly higher than cordierite DPFs. This property allows for improved heat dissipation, reducing the risk of overheating during regeneration and extending the filter’s service life.

Silicon carbide DPFs are highly resistant to chemical attack, making them suitable for use in harsh environments or with aggressive exhaust gas compositions. This feature ensures the filter’s long-term reliability and performance.

Due to their increased mechanical strength, thermal conductivity, and resistance to chemical attack, silicon carbide DPFs typically have a longer service life compared to cordierite DPFs. This extended durability can result in cost savings for your business over time.
