In the early days of the invention of condoms, the search for a condom was the ultimate proposition. The normal thin range of natural latex condoms is 0.04 millimeters to 0.09 mm, compared to "showering in a raincoat." A dozen years ago, some people proposed using a water-based polyurethane as a condom, but it was a theoretical assumption at the time, because it was difficult to implement many technical problems. 

 

Water-based polyurethane is a kind of high polymer material with good biosafety, it is widely used, and it is commonly used for coating and adhesives. But water-based polyurethane condoms are very difficult to deal with the synthetic technology of water-based polymers and the technology of ultra-thin materials. And the thickness of 0.01 mm is in itself challenging the thickness limit of the thin-film material, which is the highest technical challenge of the current water-based polyurethane material. 

 

In August 2016, lanzhou branch day health science and technology co., LTD. Announced successfully developed thin 0.01 China's first water-based polyurethane condoms, and took the lead through the food and drug administration approved, May 20, 2017, China's first waterborne polyurethane condom brand nakagawa 001 release, and through the jingdong world debut. 

 

Only two Japanese companies have mastered the production of polyurethane condoms before the arrival of the company. Nakagawa 001, broke the Japanese technological monopoly in the field of polyurethane condoms production, so far China has the high quality, safe and reliable water-based polyurethane condoms. Nakagawa thin polyurethane condoms to 0.01 001 is 1/5 of the average thickness of latex condoms, thin, almost in soap bubbles and can provide a more comfortable experience, more exquisite close skin soft tactility, many times the ordinary latex condoms heat conduction speed, real time feel the intimacy between lovers. 

 

At the same time of perfect experience, waterborne polyurethane condoms without holes, the characteristics of high density also greatly enhanced the security of the condom, in addition to effective contraception, can effectively block the HPV (human papilloma virus), HIV (HIV), HBV (hepatitis b virus), and other virus. At the same time, polyurethane condoms avoid the problem of protein caused by proteins in traditional latex condoms. 

 

China as a big country, condom annual consumption up to 9.6 billion, the average annual growth of more than 15%, domestic condom use school-age population covers nearly 700 million people, common people spending nearly 90 million, condom billions of potential market as a whole. Zhongchuan polyurethane condoms are not only cost-effective, they are also international in quality, health and safety requirements. Along with our country the first polyurethane condoms, marketization of mature, polyurethane condoms in the domestic consumption will account for fifty percent in the future market, sales worth billions, is bound to cause the condom industry and technology of China.
