With the increasing use of sex dolls, the contrast between silicone sex 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 high-grade plastics and rubber. This change in material composition has brought 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 a sex doll. The silicone material is non-porous, so it cannot penetrate the secreted liquid during contact. On the other hand, TPE sex dolls tend to accumulate these fluids, thereby reducing the efficiency of cleaning and disinfection after use.
Elasticity
Another major difference between silicone sex dolls and TPE sex dolls is elasticity. Compared with silicone materials, TPE has both rubber and plastic properties, making it more flexible and more realistic. The silicone sex doll is not easy to deform, which also makes the silicone sex doll more rigid.
Compatibility
It is inevitable to use lubricants when using sex dolls, which is very necessary. TPE sex dolls are compatible with silicone oil and water-based lubricants, but silicone sex dolls can only use water-based lubricants, otherwise, it will destroy the nature of the doll. Compared with silicone sex dolls, this difference makes TPE sex dolls more widely used.
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. However, unlike standard quality silicone, the quality of TPE is more dependent on the combination of its ingredients. The service life of high-quality TPE sex dolls will be longer than that of silicone sex 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 sex dolls have a more realistic appearance than TPE. In terms of price, because silicone has more complicated steps in manufacturing and production, and the difficulty of injection molding for dolls is also higher, because it is much more expensive than TPE materials, dolls made of TPE materials can be affordable by many people.
