Located at No. 8 Kangbao Road, Miyun Economic and Technology Development Zone, Beijing, Beijing Rain & Earth Technology Co., Ltd. (hereinafter "the Company") is one of the very few companies in China that are dedicated to research, development and manufacturing of polysulphone hollow fiber dialysis membranes and dialyzers.

For some historical reasons, production and application of hollow fiber for medical dialysis and dialyzers are almost monopolized by a couple of manufacturers in overseas countries like Germany and Japan. Although with ongoing market adjustment, prices of imported products have been significantly lowered, cure costs always stay high because they keep confidential and monopolize the hollow fiber formula and production techniques.

To break through the monopoly by foreign manufacturers, after comprehensive study and many tests of sophisticated foreign products and with continuing exploration and practices in recent years, we have successfully developed our proprietary production techniques and equipment for medical polysulphone hollow fiber membranes (hereinafter "the Membrane"). The Membrane products that are independently developed and produced by us are stable in quality, and have passed tests by the Medical Instrument Quality Supervision and Inspection Centers in Jinan and Guangzhou provinces designated by the State Food and Drug Administration of China. Currently the Membrane products manufactured by us have not only addressed the stability issue of materials formula, but also enabled us with the capability of industrial production and to significantly reduce costs by independently developing and manufacturing the membrane production lines with one machine for multiple pumps and one pump for multiple filaments.

With improved social insurance system in China, more and more nephritic patients will have access to proactive treatments and extend their lives. For more patients to see tomorrow's sun, we will continue to develop and manufacture new membrane products for the health of the people.
