Automobile Honeycomb Ceramic Substrate For Gas Filter (ALL SHAPES)
The material for catalytic converter substrate-honeycomb ceramic is cordierite.The natural cordierite exists very rare in nature,so most of cordierites are man-made substances.The major features for such cordierite are low thermal expansion coefficient,good thermal shock resistance,high anti-acid,anti-alkali and anti-erosion function and good mechanical strength.
The usual CPSI for catalytic converter substrate is 400.The shape of honeycomb ceramic can be round,racetrack,ellipse and other special shape according to customers’requirement in order to meet the different cars model requirements.
