High & New Technology
In the filed of high and new technology, Keda has mastered world advanced power semiconductor core technology and domestic advanced production technology of Acrylamide and Polyacrylamide.
Biochemical 01
We mainly use microbiological method to produce acrylamide, which engages the carrier-free microorganism catalysis technique. Compared with products produced by conventional chemical method, our products feature high purity, no cupric ion and little iron ion. The main reactant is acrylonitrile and there is little by-product and impurity. The product especially applies to the production of polyacrylamide of ultra-high molecular weight with even molecular weight distribution.
Kechuang Biochemical
Dongying Kechuang Biochemical Industrial Co., Ltd. Adheres to the industry concept of Keda Group -"green and environmental care, high efficiency and energy-saving", constantly invests in the independent innovation, and actively expands the research team to establish the core competition and become a new type hi-tech enterprise.
Advanced Bioanalysis Production Technology
The polymerization products include HMW and UHMW polyacrylamide for tertiary oil recovery, new type medium temperature resistant medium degree of mineralization polymer TS-65, new type high viscosity polymer TS-70, new type high temperature resistant high degree of mineralization polymer TS-85, etc..
Wide Applicable Range of Products
The UHMW polyacrylamide for tertiary oil recovery is mainly used in the polymer flooding operation in oilfields.
Semiconductor 02
Keda is mainly engaged in the design, production and sales of new type power semiconductor devices(power electronic devices) like IGBT, FRD and MOSFET. The company has set up sales center in Shenzhen, Zhejiang, Shandong, etc.
A first-class design and R&D team
With first-class R&D and design team, Keda products all feature leading technological level in China. And the IGBT and FRD products have filled the gap in domestic market.
Independent intellectual property right
Keda has become the first manufacturer in China that has independent intellectual property right and can provide advanced power semiconductor chips, devices and modules including IGBT, FRD, MOSFET, etc, which breaks the monopoly of foreign companies in the field of high-end power semiconductor.

Keda semiconductor high technology industry project has been recognized as a key project of the Torch Program and Shandong Province.

Keda’s hi-tech semiconductor project has gained the highest support from the Power Electronics Industrialization Program of NDRC (National Development and Reform Commission), fund support of 3 million RMB from the Key Independent Innovation Industrialization Program of Department of Science and Technology of Shandong Province, and 5 million RMB Electronic Information Industry Foundation from Ministry of Industry and Information Technology of PRC; and the project has been enlisted in the Torch Program of Ministry of Science and Technology and Key Construction Project of Shandong Province.

Keda has developed IGBT, FRD and MOSFET products of various specifications.
Applied for 28 invention patents, among which, the 1200V IGBT has been recognized as National Key New Product by the Ministry of Science and Technology.
The products are widely used in induction cooker, small power frequency converter, inverter welding machine, brushless motor control, UPS, etc.
