With the increasing use of physical dolls, the contrast between silicone dolls and TPE sex dolls has always been controversial. As the name implies, the materials used are the first comparison between the two. Silicone is a kind of rubber similar to man-made materials, while thermoplastic elastomer (TPE) is a mixture of advanced plastics and rubber. This change in material composition brings many differences between the two dolls.
Porosity
To put it bluntly, it refers to the ratio of the number of pores to the total volume of the material. The trend and rate of fluid permeability determine the porosity of the physical doll. The silicone material is non-porous, so it cannot penetrate the secreted liquid during contact. On the other hand, TPE dolls tend to accumulate these fluids, thereby reducing the efficiency of cleaning and disinfection after use.
Elasticity
Another major difference between silicone dolls and TPE dolls is elasticity. Compared with silicone materials, TPE has both rubber and plastic properties, making it more flexible and more realistic. The silicone doll is not easy to deform, which also makes the silicone doll more rigid.
Compatibility
It is inevitable to use lubricants when using physical dolls, which is very necessary. TPE dolls are compatible with silicone oil and water-based lubricants, but silicone dolls can only use water-based lubricants, otherwise it will destroy the nature of the doll. Compared with silicone dolls, this difference makes the use of TPE dolls wider.
Durability
The pressure that the material can withstand and the liquid that may be in contact during use determines the quality and durability of the doll. For standard silica gel and TPE, silica gel has a relatively long service life. But unlike standard quality silicone, the quality of TPE is more dependent on the combination of its components. The service life of high-quality TPE dolls will be longer than that of silicone dolls.
Other
TPE sex dolls are more flexible, so they have enough slip resistance when in use. On the other hand, the rigid material of silicone also makes silicone dolls have a more realistic appearance than TPE. In terms of price, there are more complicated steps in the manufacturing and production of silicone, and it is also more difficult to mold the doll, because it is much more expensive than TPE material, and TPE material dolls are affordable by many people.
