In 1992, the company's predecessor, Zhejiang Sunflower New Materials Co., Ltd., was established, specializing in PVP production. Mr. Wu Jiaxiang, the chief expert of the national PVP research and development project, served as the general manager. In 2002, the company was restructured into a private enterprise and Hangzhou Sunflower Technology Development Co., Ltd. (STD) was established to continue to develop and produce PVP series of technical and cosmetic products. The company has a GMP production line with an annual output of 600 tons of low molecular weight povidone (povidone K12, K15, K17, K25, K30), 800 tons of high molecular weight povidone (povidone K60, K90, K120), 300 tons of high stability povidone iodine, and 100 tons of sodium chondroitin sulfate.

Hangzhou Rainbow Import & Export Co., Ltd mainly produces chemical products, such as povidone, cross-linked povidone, povidone iodine, chondroitin sulfate, etc. The following are the characteristics of these products:

1. Povidone: It is a linear 1-vinyl-2-pyrrolidone synthetic polymer that can absorb toxins. It is usually made into injections and used for certain poisoning diseases.

2. Cross-linked povidone: It is a water-insoluble synthetic cross-linked N-vinyl-2-pyrrolidone homopolymer. It is a white or off-white powder, almost odorless, and hygroscopic. It is insoluble in water, ethanol, chloroform or ether. It has a high capillary/water content, a large specific surface area, extremely strong hydration ability, high and rapid water absorption, strong water absorption and expansion ability, and a swelling coefficient of 2.25-2.30. It also has the same complexing ability as polyvinyl pyrrolidone and can complex a variety of substances. It is often used as a water-insoluble tablet disintegrant, dry adhesive, filler and excipient, etc. It can also be used as a dissolution promoter.

3. Povidone iodine: There are many dosage forms. The solution can be used for skin fungal infections, suppurative dermatitis, small-area mild burns and scalds, and small-area skin and mucosal wounds. The suppository is used for candidal vulvovaginal disease, bacterial vaginosis, mixed infection vaginitis, and hemorrhoids; gels, creams, and vaginal effervescent tablets are used for candidal vulvovaginal disease, bacterial vaginosis, and mixed infection vaginitis; the film is used to treat candidal vaginitis; the gargle is used for oral diseases such as stomatitis, oral ulcers, pharyngitis, pericoronitis, and periodontitis. It can also be used for disinfection before oral surgery and daily oral disinfection and health care.

4. Chondroitin sulfate: There are oral preparations, injections, and eye drops. Oral preparations can lower blood lipids, treat hyperlipidemia, prevent and treat various cardiovascular diseases, treat various pains, promote healing of traumatic wounds, assist in the treatment of diseases such as nephritis and chronic hepatitis, and also have anti-tumor effects; injections are mainly used for the auxiliary treatment of atherosclerotic diseases, neuralgia, neuralgia, and joint pain; eye drops have the effect of promoting corneal wound healing, exudate absorption and eliminating inflammation, and are used for diseases such as keratitis, corneal injury, and corneal ulcers.
