Silicon Carbide Diesel Particulate Filter Substrate
Product Description:
Our Silicon Carbide (SiC) DPF Substrate is a high-performance ceramic carrier specially developed for diesel engine exhaust aftertreatment systems.Ideal core filter component for diesel exhaust purification, particulate filtration and environmental emission compliance.
Made of premium silicon carbide material, this filter substrate features extreme high temperature resistance, excellent thermal shock resistance and high mechanical strength. Its precise honeycomb porous structure can efficiently capture soot, particulate matter and black smoke from diesel exhaust, realizing effective smoke removal and emission reduction.
Compared with traditional cordierite substrates, SiC filter substrate owns better thermal conductivity and longer service life, stable performance under long-term high-temperature working conditions. Custom size & custom structure are available to meet various demands of trucks, engineering machinery, generators and heavy-duty diesel equipment.
Product Feature:
1.Higher carbon loading capacity
Supports high carbon loading up to 10g/L, can accumulate more soot and particulate matter before regeneration, extending service intervals and reducing frequent cleaning.
2.Superior high temperature resistance
Withstand extreme operating temperatures, ideal for high-temperature regeneration of diesel engines.
3.Outstanding thermal shock resistance
Low thermal expansion coefficient, no cracking under rapid heating and cooling cycles.
4.High thermal conductivity
Uniform heat distribution, more stable and efficient regeneration performance.
5.High mechanical strength & vibration resistance
Adapt to harsh working conditions for heavy-duty trucks and construction machinery.
6.High filtration efficiency
Effectively capture diesel soot, black smoke and fine particles for exhaust purification.
