Development of latex free polyurethane condoms in China
Development of latex free polyurethane condoms in China
From the beginning of the invention of condom, the pursuit of the thinness of condom has become an ultimate proposition. The normal thickness range of natural latex condom is 0.04 mm to 0.09 mm, which is vividly compared to "bathing in a raincoat". More than ten years ago, it was proposed that water-based polyurethane be used as condom, but at that time, it was only a theoretical assumption, because it involved many technical problems, it was difficult to achieve.
Waterborne polyurethane (WPU) is a kind of polymer material with good biological safety, which is widely used as coating and adhesive. However, waterborne latex free polyurethane condoms involves the synthesis technology of waterborne polymer materials and the molding technology of ultra-thin materials, which is very difficult. Moreover, the thickness of 0.01mm itself is challenging the thickness limit of film materials, which is the highest level technical challenge of current waterborne polyurethane materials.
In August 2016, Lanzhou Ketian Health Technology Co., Ltd. announced the successful development of China's first water-based latex free polyurethane condoms Bozhi 0.01, which was approved by the food and Drug Administration for listing. On May 20, 2017, China's first water-based latex free polyurethane condoms brand Zhongchuan 001 was officially released, and it was launched by Jingdong.
Before the advent of Nakagawa 001, only two Japanese companies had mastered the production technology of latex free polyurethane condomss. With the advent of Nakagawa 001, Japan's technological monopoly in the field of latex free polyurethane condoms production has been broken. So far, China has high-quality, safe and reliable waterborne latex free polyurethane condomss. The thickness of Zhongchuan 001 latex free polyurethane condoms is as thin as 0.01, which is 1 / 5 of the thickness of ordinary latex condom. It is almost as thin as soap bubble. It can provide more comfortable experience, softer and more delicate touch to the skin. It is multiple times of the heat conduction speed of ordinary latex condom, and can feel the intimate changes between lovers in real time.
While bringing a perfect sense of experience, waterborne latex free polyurethane condomss have no holes and high density. They also greatly enhance the safety of condoms. In addition to effective contraception, they can also effectively block HPV (human papillomavirus), HIV (HIV), HBV (hepatitis B virus) and other viruses. At the same time, latex free polyurethane condoms can avoid the allergy problem caused by protein in traditional latex condom.
As a country with a large population, China's annual condom consumption is as high as 9.6 billion, with an average annual growth rate of more than 15%. The domestic condom use age group covers nearly 700 million people, and the common consumption group is close to 90 million. The overall potential condom market is as high as tens of billions. Nakagawa latex free polyurethane condoms is not only more cost-effective, but also comparable to the international market in quality, health and safety. With China's first latex free polyurethane condoms on the market, market-oriented mature, latex free polyurethane condoms in the future will occupy 50% of the domestic consumer market, sales scale reached 10 billion, is bound to cause China's condom industry technology change.
