Hangzhou Dadong Foreign Trade Co., Ltd.

Our company is a bamboo R&D center and a base fro the production, study, research and educational training under the State Forestry Administration, and currently is the specialized enterprise engaged in manufacture and deep processing of wood and bamboo active carbon of the highest developing capacity and output and best product quality in China. It developed the Chinese first continuous thermal extrusion-casting type active carbon filter core production line. It uses USA F500 standard base carbon and unique formulation and process, which increases the carbon content of filter core from 50% to at least 80%, eliminates the backwards technique of manual-preparation, fills domestic gap and is granted with several state patents (Patent No.: ZL 98114679.1, ZL01131145.2, ZL01259217.X, ZL 983099626.6 and ZL 98309961.8). Now, it reaches an annual capacity of 2 million sets in 8 series (100 varieties) and has a high production capacity. Its main products include thermal extrusion-casting type active carbon filter core and plate (CTO), bulk active carbon filter core (UDF), polypropylene fusion-spray filter core (PP), softened water resin filter core (UDFR), de-scaling compound filter core (UACF), straight-sealed foldable filter core, porous ceramic filter core, high grade cigarette filter tip, wood charcoal, machine-made charcoal, barbecue-purpose charcoal, elegant fumigating charcoal (cake-shaped and strip-shaped), shaped charcoal (ball, cylinder, column, cake, strip, cellular, rectangular, circular and hexagonal shape), bamboo charcoal, bamboo vinegar liquid, active carbon series products (portable hand-warming stove, warming sheet and pad), indoor air purifying charcoal (especially for removal of formaldehyde and benzene), water purifying-purpose of silver-carried active carbon for filter unit (WJAG), global active carbon, golden fish filter bag and other active carbons. The products are widely used in purifying water in petroleum, chemical, food, beverage, medicine, hygiene, drinkable water, daily water, and urban sewage treatment.
Our monthly market share volume reaches over 150000 sets due to advanced inspection equipment, strict quality assurance system, micro-computer information network, convenient traffic and telecom, thorough after-sales service and good reputation. Now, it annually produces and sells 5000 tons of active carbons and becomes the largest production base of filtering materials and active carbon in China.
