Selective Catalytic Reductant
PD6976472251106000011
Selective Catalytic Reduction (SCR) is a highly efficient emissions control technology designed to reduce nitrogen oxides (NOₓ) from diesel engine exhaust. As a core component of modern diesel aftertreatment systems, it plays a pivotal role in meeting strict global emission standards and mitigating air pollution.
The SCR system operates by injecting a urea-based reductant—commonly known as Diesel Exhaust Fluid (DEF) or AdBlue—into the exhaust stream. At an optimal temperature range of 200-400°C, the reductant vaporizes and reacts with NOₓ on the surface of a specialized catalyst (supported by cordierite or silicon carbide substrates). This selective chemical reaction converts harmful NOₓ into harmless nitrogen (N₂) and water (H₂O), with minimal impact on other exhaust components.
Widely adopted in diesel-powered trucks, buses, construction machinery, generators, marine vessels, and industrial engines, SCR systems typically integrate with DOC (Diesel Oxidation Catalyst) and DPF (Diesel Particulate Filter) for comprehensive pollutant control. Together, these devices ensure compliance with standards such as Euro 4/5/6, EPA, and China VI, achieving NOₓ conversion efficiencies of 90% or higher while enabling efficient engine operation.
cordierite substrate
PD6976472251106000008
Cordierite substrates are ceramic carriers made from cordierite (2MgO·2Al₂O₃·5SiO₂), a material celebrated for its ultra-low thermal expansion coefficient, good thermal shock resistance, and cost-effectiveness. They stand out as reliable choices for temperature-fluctuation-prone applications.
With a thermal expansion coefficient as low as 1-2 ppm/°C (25-800°C), these substrates resist cracking even under rapid heating and cooling. They also offer moderate mechanical strength and chemical stability, suitable for both industrial and automotive scenarios.
Widely used as catalyst supports in automotive exhaust systems (three-way catalysts, diesel particulate filters), industrial catalytic reactors, and high-temperature gas filtration equipment, cordierite substrates can be customized into honeycomb structures, specific sizes, or porous formats to enhance surface area and reaction efficiency.
silicon carbide substrate
PD6976472251106000007
Silicon Carbide (SiC) substrates are high-performance ceramic materials renowned for exceptional thermal conductivity, superior electrical insulation, and extreme environmental resilience. As a advanced functional carrier, they outperform traditional ceramic and metal substrates in demanding scenarios.
Available in single-crystal (4H-SiC, 6H-SiC) and sintered grades, SiC substrates boast thermal conductivity ranging from 120-400 W/(m·K), withstand temperatures up to 1200°C+, and exhibit strong corrosion resistance. These traits make them ideal for high-power, high-temperature, and high-voltage applications.
Key applications span power electronics (EV inverters, renewable energy converters), semiconductor devices (SiC MOSFETs/IGBTs), aerospace components, and industrial heating equipment. They can be customized via precision cutting, drilling, polishing, or metallization to meet specific project requirements, enabling more efficient and compact system designs.
metal substrate

Metal substrates are base materials crafted from metals or metal alloys, valued for their excellent thermal conductivity, high mechanical strength, and strong processability. They serve as critical components for thermal management, structural support, and functional carrier applications across industries.
Common types include aluminum, copper, steel, titanium, and specialized alloys like aluminum-magnesium or copper-nickel. Each type caters to distinct needs—aluminum and copper excel at heat dissipation, steel offers robust structural performance, while titanium provides superior corrosion resistance.
Widely used in power electronics (such as insulated metal substrates/IMS), LED heatsinks, automotive components, aerospace structures, and printed circuit boards (PCBs), metal substrates thrive in vibration-prone, heavy-load, or high-heat environments. They can be customized via surface treatments (anodizing, plating, passivation), cutting, drilling, or grooving to meet specific project requirements.
vermiculite liner
PD6976472251106000005
Vermiculite liners are pads made from vermiculite, a mineral known for its exceptional thermal insulation, fire resistance, and sound absorption properties. These liners feature high-temperature resistance (up to 1000°C+), low thermal conductivity, and light weight, making them ideal for multiple applications.
Commonly used in industrial kilns to reduce heat loss and protect equipment, as fireproof partitions in buildings to slow down fire spread, and as soundproofing layers in vehicles and machinery rooms, vermiculite liners offer reliable performance in harsh conditions. Their porous structure also aids in sound absorption, adding to their versatility. Whether for thermal insulation, fire protection, or soundproofing, vermiculite liners provide an efficient and durable solution.
