We are Beihai Huihuang Langjie Environmental &Tech (Corp) Co,.Ltd,the manufacturer of Foam ceramic substrate.
Foam ceramic substrate is a third-generation porous ceramic product after the common porous ceramics and cellular porous ceramic product, which has the characteristics of small resistance, high strength, high-heat resistance, erode resistance.
Foam ceramic substrate is coated with the alumina, rare earth and the noble metal ( Pd, Pt and Rh), the SiC foam filter accomplishes the goal of purification of the automobile.
The advantages which suprior to the honeycomb cremaic substrate made of cordierite are at following aspects: faster thermal mass, higher intension and etc. The density of Sic foam flter can be designed by the engine emission capacity to reduce the back presssure, which can be 10, 15,25 30, 50 and 60 PPI.
