Honeycomb Thermal Store Catalyst Ceramic - Beihai Kaite Chemical Packing Co.,Ltd.

Honeycomb thermal store catalyst ceramic is used for waste gas treatment(RTORCO) of the different requirements, selecting many kinds of new highly effective ceramic material to make. It has the following notable characters: large specific surface area, little resistance loss, small heat-expand and cold-contract coefficient, high water-absorbing ratio, good fracture resistance and moderate Millipore aperture.
