With the advancement of technology and materials, sex-dolls have dramatically improved. So much so that materials are starting to mimic real skin and flesh. Gone are the days of really uncomfortable and skin slicing plastic.

TPE stands for Thermoplastic Elastomer, also known as thermoplastic rubbers. It is manufactured from a mix of polymers. In the case of sex dolls, plastic, and rubber. This combination of polymers results in a material that consists of thermoplastic (plastic) and elastomeric (rubber) properties.

Furthermore, it can be stretched up to 5.5 times length. These properties contribute to its suppleness and softness. As a result, TPE is a reasonably popular material used in everyday items too because it can be used to make items that possess rubber-like features but still utilize the efficiency of current injection molding techniques since it can conform to irregular shapes when heated. This makes it more economical to shape and reshape.We shall now go over more specific pros and cons of TPE.


When making TPE sex dolls, two ingredients are mixed, a thermoplastic, and an elastomer. Because these materials respond well to injection molding, mass production is efficient and maximized. Because of these efficiencies, cost reduction has allowed for a cheaper doll. A doll can cost $800 to $2,000.

Since TPE is a mix of a thermoplastic and an elastomer, properties of these materials can be altered to create an ideal texture. Manufacturers have created a soft and elastic blend providing a very life-like touch. As a result, it is more realistic compared to Silicone.

Breasts and buttocks will wobble and act naturally when the doll is moved back and forth, given the unique characteristics of TPE.

In terms of the extent of sex positions, TPE is more elastic, which makes the dolls more flexible. This contributes to the broader variety of sex positions which the doll may handle.

Since TPE is not Silicone-based, dolls made from this material are compatible with silicone-based lubricants, as well as water-based lubricants.


TPE is a porous material. Because of this, the stains from clothes my seep into the porosities, making it susceptible to stains from clothes. If this happens, stain removers may be purchased from

Another downside to porosity is the ability to retain water in the form of humidity. This makes the doll prone to mold growth, which is very unhygienic. To avoid this, the doll must be thoroughly dried after cleaning.

Because TPE is partially made of a thermoplastic, the same properties that allow being easily injectable makes it susceptible to heat. In worst cases, TPE can start losing its consistency or enter the glass transition phase upon reaching 104 Fahrenheit (40C).

Unlike TPE, Silicone is not a mixture of a thermoplastic and an elastomer. It is classified as a thermoset. Unlike TPE, its shape and qualities are fixed once it cures. It is heat resistant and rubber-like. Given these qualities, it is used in a wide range of applications that maximizes its quality. Such examples of uses are in lubricants, medicine, glue, cooking utensils, etc.

One of the great qualities of Silicone is its ability to retain shape even under extreme pressure. Also, it is very heat resistant giving it the ability to withstand being boiled for sterilization. Furthermore, it is highly inert since it does not react with most chemicals, which makes it medically safe to be used as implants.

Unlike TPE silicone, Silicone is non-porous, making it resistant to clothe stains. It is, therefore, easier to clean.

Another plus to its non-porous nature, it doesn?t retain humidity, unlike TPE. This allows it to be sterilized using boiling water similar to sterilizing utensils and medical equipment.

Given that it is a thermoset, its initial curing phase is not dependent on cooling. It is catalyst based, which makes it significantly less sensitive to heat-induced deformation should it be subject to heat. This means these dolls could be enjoyed while bathing in warm to hot water.

Silicone being a thermoset means that once it is cured, it is firm and cannot be altered. Because of this smaller margin for error, it becomes more expensive, reaching $2,000 to below $5,000.

Silicone is not as soft as TPE. It feels more dense and stiff to touch as compared with TPE. It is more rubber-like than life-like.

When it comes to buttocks and breasts, given the more rubber-like consistency, these features will not wobble when the doll is rocked back and forth as they would with TPE.

Given the lubricants, it may be exposed to Silicone is not the most durable polymer.

Aside from being firm, Silicone can also feel sticky to the touch. As suggested by others, baby powder can reduce this giving it a better feel.

In conclusion, TPE is an excellent material of choice if you?re looking for a very realistic sex doll. It is very realistic to the touch and flexible to accommodate multiple sex positions. But with these great features, the user must not mind the extra care needed to maintain it. On the other hand, Silicone is perfect if you do not have time to keep the sex doll, and you are not that sensitive to the feel and touch.
