Product Overview
The material for catalytic converter substrate 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 catalystic converter substrate is 400. The shape of honeycomb ceramic can be round, racetrack, ellipse and other special shape according to the customera s requirement in order to meet the different cars models requirements. The major technical parameters for cordierite are as below: Thermal expansion coefficient: 1.6-2.0A 10-6/a i 20-800a i Absorption rate: 20-30% Inner wall thickness: 0.2A 0.02mm CPSI (cell pieces per square inch): 200-600 Bulk density: 0.5A 0.05g/cm3 Crushing strength: a Y14Mpa (on the top) a Y4Mpa (on the side) Soften temperature: a Y1360a
