From the beginning of the invention of condoms, the pursuit of thin condoms has become an ultimate proposition.Natural latex condoms, whose normal thickness ranges from 0.04 mm to 0.09 mm, have been likened figuratively to "bathing in a raincoat".More than a decade ago, it was proposed to use waterborne polyurethane as a condom, but at that time, it was only a theoretical hypothesis, because it involved many technical problems and was always difficult to achieve.
Waterborne polyurethane (wpu) is a kind of polymer material with good biological safety, which is widely used in coatings and adhesives.However, the water-borne polyurethane condoms involve the synthesis technology of water-borne polymer materials and the forming technology of ultra-thin materials, which is very difficult.Moreover, the thickness of 0.01mm itself is challenging the thickness limit of thin film materials, which is the highest technical challenge of waterborne polyurethane materials at present.
At the same time to bring the perfect experience, waterborne polyurethane condoms without holes, high density characteristics, also greatly enhance the safety of condoms, in addition to effective contraception, but also can effectively block HPV (human papilloma virus), HIV (HIV), HBV (hepatitis b virus) and other viruses.At the same time, polyurethane condoms avoid the allergy problems caused by the protein found in traditional latex condoms.
As a country with a large population, the annual consumption of condoms in China is as high as 9.6 billion, with an average annual growth rate of more than 15 percent. Nearly 700 million domestic people of condom use age are covered, and nearly 90 million people are commonly used. The overall potential market of condoms is as high as tens of billions.Zhongchuan polyurethane condoms are not only more cost-effective, but also meet international standards in terms of quality, health and safety.With China's first polyurethane condoms on the market, the maturity of the market, polyurethane condoms in the future in the domestic market will occupy 50 percent of the consumer market, sales reached 10 billion, is bound to cause the Chinese condom industry technology change.
