The American scientists created future condoms


They differ in a special covering which reduces friction coefficient at contact with water. Scientists of Boston University could solve a problem of a lack of lubricant which arises when using condoms. The covering developed by them reduces friction coefficient at contact with water thanks to hydrophilic polymers. Writes New York Post about it. With a new covering condoms slide more, than usual, and do not lose these properties over time. For their production experts involved latex which was covered with mix from hydrophilic polymer. The new product also passed test during which the latex covered with hydrophilic polymer rubbed about the polyurethane surface covered with water with a speed of 22 millimeters a second. The same test was put to also the usual latex covered with water-based lubricant. As a result it was succeeded to find out that the friction coefficient between latex, the covered hydrophilic polymers and a polyurethane surface during the experiment was 53 percent lower, than at usual latex, and it is approximately equal to coefficient which is reached at friction of the latex covered with lubricant. However throughout testing the result of plain latex with lubricant gradually decreased while the latex processed by a new covering - remained stable. Earlier it was reported that in the USA created condoms from hydrogel which increase sexual excitement. News from the Correspondent.netv of Telegram.
