Co., Ltd. is a professional manufacturer of ceramic substrates, diesel particulate filters (DPF), catalytic converters, catalyzed DPFs, diesel oxidation catalysts (DOC), VOC oxidation catalysts, metallic substrate catalysts and other similar products in China. And we have cooperated with Phitecs GmbH in Germany for years. In 1980s, we began to produce different kinds of industrial ceramics, such as ceramic substrates for auto-catalysts, honeycomb monoliths for RTO applications and related products. In the early 1990s, we began to develop diesel particulate filters (DPF), catalytic converters, diesel oxidation catalysts (DOC), catalyzed DPFs (CDPF), VOC oxidation catalysts and metallic oxidation catalysts. As a result of continuous development, we now obtain many patents of coating technology in the world. At present, we have 2 R&D centers and 3 factories worldwide. Over 90% of our products are exported to North America, EU, ...[More]Korea and some Southeast Asia countries.
