up to september 2014, bluestar dongda was authorized 71 patents by the state intellectual property office, and there are 9 invention patents, 61 utility model patents, and 1 appearance patent of them. the patents cover the technology areas of such as pu products synthetising, applying, and detecting, etc.
bluestar dongda adheres to the principle of "active application, the effective utilization", and applied the patent resources to the product technical supporting and production scientifically effectively. the successful application of "high activity synthesis method of rigid foam ppg for spraying", "synthetic method of slow rebound foam ppg" and the other patented technologies, which filled the company's high-end ppg areas of products and technology gaps of bluestar dongda, has achieved considerable economic benefits for bluestar group. "soft foam flame-retardant ppg and synthesis method" which introduced synthesis method of structural flame-retardant ppg has been implemented on a large scale production in bluestar dongda existing installations, this method does not increase equipment and the staff cost, output flame-retardant ppg products have excellent flame retardant properties, no additional flame retardant in the preparation of polyurethane products that can achieve good flame effect, to meet the high-end ppg customers requirements of flame retardant. for particle size and solid content determination, there is no relevant national standards. dongda researchers in their daily work diligently summary, dare to innovate, trial and error, worked out an innovated ppg particle size and solid content detecting method, and successfully applied for patents. the two methods are first of its kind in the industry, the operations are simple, and the results are reliable. the two patents, "detecting method for the particle size of a kind of pop", "detecting method for the solid content of the ppg," has become an important standard for pop index detection of blue star group and ppg industry. declaration of national standards written based on two patents of measurement method also underway.
at present, there are several patents of bluestar dongda in accepting and substantive examination steps. we will continue developing technology research and patent application, and further enhance product quality, improve market competitiveness, make due contributions for bluestar group and the entire industry.
