This material is much more popular for many reasons. For starts, the obvious one is that it is much cheaper in terms of price, which is something that many people do consider, since TPE sex dolls are much more affordable, and silicone dolls can often cost a couple thousand dollars more. TPE does require a bit more care than silicone dolls, and they tend to need his in order to last longer, but it’s still a great type of doll to own.
Cheaper sex dolls are inflatable, using air. These dolls, representing the lowest price-range (less than US $75), are usually made of welded vinyl and bear only a passing resemblance to actual people. They have an artificial and typically crudely designed vagina or penis, but due to their affordability many users are willing to overlook their shortcomings. They often burst at the seams after a few uses, although they are commonly given as gag gifts and therefore many may not be used at all. In Russia for some years the Bubble Baba Challenge humorously featured participants river rafting on blowup dolls as a matter of entertainment but in 2013 the race was cancelled on "health and safety" grounds.
Now, TPE stands for thermoplastic elastomer, which is essentially a mixture of polyvinyl chloride and silicone. This is a type of skin that is very soft, and it mimics the feeling of human skin. TPE is way more realistic in feeling and it definitely mimics the feeling of human skin. It also is much cheaper than silicone alternatives, sometimes even hundreds of dollars cheaper. TPE also allows you to move the doll around in various ways, since it has more flexibility. TPE dolls don’t really need to be bathed, but you can, just be mindful of the water. It also is hypoallergenic as well.
