Al2O3 Ceramic Substrates Cellular For Catalytic Converters
Description:
After coated with catalysts, this product is applied in catalytic converter of gasoline vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V.
Benefits of Products:
● Thin wall thickness
● Low pressure drop
● High surface area
● Height compressive strength
● Low thermal expansion coefficient
● Good thermal impact resistance and thermal shock resistance
● Excellent compatibility with various active composition in catalyst
●Good performance in cold start, low ignition temperature, quick temperature rise, little air resistance, and high conversion efficiency.
