Honeycomb Ceramic Catalyst Substrate
Honeycomb ceramic catalyst substrate is used for gasoline vehicle catalyst converter of the exhaust gas purification treatment after coating catalyst. It can catalyze and purify the exhaust. The main material of the honeycomb ceramic catalyst substrate is cordierite. It can catalyze and purify the exhaust gas of the vehicle. We could provide 300cpsi, 400cpsi, 600cpsi honeycomb ceramic catalyst substrate. The height is within 200mm. The shape of the cross section could be round shape, ellipse shape, runway shape, pear shape or other shapes as per requirement of customers.
