 Polyurethane can be considered better than latex in several ways : it conducts heat better than latex , is not as sensitive to temperature and ultraviolet light ( and so has less rigid storage requirements and a longer shelf life ) , can be used with oil @-@ based lubricants , is less <unk> than latex , and does not have an odor . Polyurethane condoms have gained FDA approval for sale in the United States as an effective method of contraception and HIV prevention , and under laboratory conditions have been shown to be just as effective as latex for these purposes .
