A Comparison Between TPE and Silicone Sex Dolls

Ever since the first sex dolls were created, these sex aids have already come a long way. The first sex dolls were inflatables. However, they feel uncomfortable to use and do not give enough sexual satisfaction.  You would not even believe that people back then were able to settle for those types of sex dolls. 

But with the ever-advancing technology that the world has, sex dolls have improved dramatically. In fact, the materials used to build their skins can mimic the feel of real skin and flesh. Needless to say, sex doll users would never have to go back to the days when dolls feel uncomfortable and cold.

Moreover, the materials used for a sex doll dictates almost 90 percent of how it feels when you use it. For this reason, it is important that you give yourself some time in knowing the materials that are used to build the sex doll that you are planning to buy. 

There are two options when choosing a love doll: thermoplastic elastomer or TPE and silicone. For you to identify which material you should choose, below are the advantages and disadvantages of the two.

TPE and Silicone: The Pros and Cons

TPE Sex Dolls

Thermoplastic elastomers or TPE is made from a mixture of polymers. For sex dolls, these polymers are rubber and plastic. This combination creates a material that has the smoothness of plastic and the elasticity of rubber. 

In addition, TPE is stretchable up to 5.5 times its length. This property is the reason why TPE sex dolls are supple and soft and are comfortable to use. 

TPE possesses rubber-like features and can utilize the efficiency of today’s injection molding techniques since it can be easily shaped when heated. For this reason, TPE is a popular material that is used in other items other than sex dolls. 

The Advantages of TPE

As mentioned, the TPE material is composed of plastic and rubber. It responds well to injection molding. For this reason, there is efficiency in terms of mass production. 

Because TPE can be easily mass-produced, TPE sex dolls are becoming cheaper. A single TPE sex doll can cost anywhere between $800 to $2,000.

In addition, the amount of plastic and rubber combined when making TPE can be altered. This allows sex doll manufacturers to create an ideal texture. Because of this, sex dolls are now soft and elastic and has a very realistic feel. 

The unique characteristics of TPE also allow the sex dolls’ buttocks and breasts to wobble back and forth like a real human woman’s breasts and butt would when you are pounding your sex doll.

In terms of positioning your doll during sex, TPE sex dolls are more flexible since their material is elastic. For this reason, TPE sex dolls have a wider variety of sex positions that they can handle. 

The Disadvantages of TPE

The TPE material is porous. This means that its porosities may absorb stains from clothes and other materials. But if this happens, you can buy stain removers from any sex doll stores online.

This porosity of TPE has another downside. It can retain water in the form of humidity. Due to this, TPE sex dolls are prone to mold build-up, which can cause you irritation and other skin problems. In order to avoid, TPE sex dolls must be dried thoroughly after you clean it. 

Moreover, since TPE has a thermoplastic material in its composition, it makes it susceptible to heat. In some cases, this material can enter the glass transition phase and lose its consistency once it reaches 140 degrees Fahrenheit or 40 degrees Celcius. 

Silicone Sex Dolls

Unlike TPE, silicone is considered a thermoset. Meaning, its shape, and qualities are permanent once it cures. In addition, silicone is rubber-like yet is resistant to heat, giving it the ability to withstand extreme heat even when being boiled for sterilization. 

Moreover, one of the greatest qualities of silicone is its ability to keep its shape regardless of how much pressure is applied to it. 

The Advantages of Silicone

Silicone sex dolls are easier to clean. This is because the silicone skin of the doll is non-porous. Meaning, it is resistant to stains from clothes and other materials.

Since silicone is non-porous, it does not absorb the humidity around it. For this reason, silicone sex dolls can be sterilized through boiling.

Moreover, the thermoset quality of silicone sex dolls makes them less sensitive to deformation caused by heat. For this reason, sex doll owners can enjoy taking a warm bath with their silicone sex doll without worrying that it might get deformed or its skin might melt. 

The Disadvantages of Silicone

Silicone is a thermoset. So, once it has cooled done, it will become firm and the shape is permanent. Thus, the shape cannot be altered. Silicone sex dolls have a smaller margin for error. For this reason, it is more expensive compared to TPE sex dolls. A single unit of a silicone doll ranges from $2,000 to $5,000.

In addition, silicone sex dolls are not as soft as TPE sex dolls. It also feels more stiff and dense to touch. Furthermore, it is more rubber-like than life-like. 

As mentioned, a silicone sex doll is less realistic in comparison to TPE sex dolls. For this reason, you cannot expect its breasts and buttocks to wobble when you rock the doll back and forth.

Moreover, silicone sex dolls are more sensitive to lubricants. Exposing your silicone doll to non-water lubricants may cause it stains and damages.


Now that you have all the information that you need about TPE and silicone sex dolls, the choice of which one you will purchase is up to you. In addition, the durability of the doll you will buy does not depend on its materials. Instead, it depends on how you use and take care of it. So, regardless of the type of material your doll has, proper care and usage is the most important factor.
