Lifelike sex dolls have taken every corner of the world by storm and men at all stages of life are openly embracing their love and need for an attractive doll. If you haven’t lived under a rock in the last 6 months, you know that lifelike sex dolls come in a variety of materials, but the two most popular sex doll materials are TPE and silicone. Almost all high-quality, lifelike dolls are made of either of these two materials because both are ultra-realistic, durable, and give the doll owner a human-like feel and sensation.














If you are buying a sex doll for the first time, you may be confused about which material is better for TPE or silicone. The material of the doll plays a big role in helping you decide on the doll you want to take home. This article will outline the pros and cons of each material to help you better understand the differences between the two and make your final decision.

Let’s take a look.

What is a TPE material

Thermoplastic elastomer (TPE) stands for thermoplastic elastomer, which is a blend of several polymers (such as rubber and plastic) that have both thermoplastic (plastic) and elastomeric (rubber) properties. In other words, TPE materials are as strong as plastic and as soft and pliable as rubber. Think of it as a plastic that can stretch up to 5.5 times its original length and is very soft.

What makes it a top choice for sex dolls is its ability to utilize current injection molding technology in the manufacturing process, which makes it both economical and surreal to touch and feel.

How does TPE material feel

This feeling depends on the shape and quality of the material, but in terms of the touch we have all experienced, we think it is close to touching the elastic rubber toys that often appear in shopping malls. If you’ve ever touched these balls, imagine how good and realistic your next sex doll will feel.

Advantages of TPE materials

The following are the most popular advantages of TPE materials.

Material properties

The most important criterion for choosing sex doll material is its performance. When it comes to TPE sex dolls, it feels almost like real human skin – except that it’s stretchable because it’s a mixture of rubber and plastic polymers. No matter how many times you stretch it, it will quickly return to its natural length. Due to this flexibility, TPE doll is durable and not easy to damage. In addition, due to the increased flexibility, you can hold your doll in a variety of positions.


The softness of sex doll material is directly proportional to the feeling of lust and feeling. TPE material is very soft and elastic, providing lifelike touch. If you close your eyes and rub your fingers on a TPE sex doll, you won’t know whether you’re touching a sex doll or a real woman – which is what triggers your sexual energy.

This feature becomes even more important for your doll’s breasts and hips. Because of elasticity, breasts and hips will give you such a soft feeling when you squeeze them.


Compared with silicone doll, one of the biggest advantages of TPE sex doll is its low price. A high-quality TPE doll can be bought in the range of $900-2500, although TPE is more realistic than silicone. The reason is that TPE materials are easy to recycle, which is why you can get high-quality dolls at a more affordable price.


Over the years, TPE has proved to be one of the best hypoallergenic materials, making it the first choice for realistic sex dolls. If not contaminated, TPE has the best hypoallergenicity and will not cause any allergic reaction to human skin. Because of this, owners of sex dolls can use TPE dolls for a long time without any safety risks.

In addition, TPE dolls are compatible with both water-based and silicon-based lubricants, making it easier for the owner

Heat resistance

TPE material, like silicone, can resist medium and low temperatures and is relatively stable at various temperatures. But they melt at high temperatures, putting you at risk. Therefore, it is always recommended to store TPE dolls in a cold place – especially if you don’t intend to use them for a long time.

Disadvantages of TPE

The following are the biggest disadvantages of TPE dolls:

TPE dolls are difficult to clean. If your doll is stained, it needs enough time to remove it. Additionally, thermoplastic elastomer materials are highly porous and retain moisture, making it more difficult to clean and dry all cavities and holes. If anything is still wet after drying, it can lead to mold growth over time, negatively affecting your safety and health. So, be sure to do a thorough cleaning and dry her thoroughly.

Its high porosity makes it more sensitive to stains on clothing and other contact materials. Sex doll lovers are advised to use a dye cream to remove stains before leaving permanent marks.

TPE materials have poor heat resistance, so soaking them in hot water or storing them at high temperatures can cause serious damage to their skin. What’s more, exposing it to direct sunlight long enough can also wear away its skin. Generally, TPE starts to lose consistency above 40°C.

TPE is a sticky substance that can be irritating during sex. However, this problem can be solved with infant formula.

What is silicon material

Silicone is a polymer that gives it a rubbery feel. Depending on its formulation, silicone can be very soft and flexible and retain its original shape under high pressure. In addition, it is resistant to high temperatures and is used as an inert material in medical devices.

Advantages of silicone as a material for sex dolls

Heat resistance

Silicone sex dolls have a higher heat resistance than thermoplastic elastomers (TPE) and can easily withstand temperatures above 40°C. It does not lose its consistency in direct sunlight, but is still not suitable for prolonged exposure to direct sunlight.

Highly realistic

Just like TPE, silicone sex dolls have the most realistic skin, including vaginal and anal cavities, and can provide the same sexual pleasure as real women. Some doll owners argue that silicone sex dolls are less realistic than TPE in terms of material softness and flexibility, but they are more resistant to water, heat and stains.

Easy to clean and maintain

The biggest advantage of silicone dolls is that they are easy to clean and maintain. Unlike TPE dolls, it does not require much maintenance because it is stain resistant. In addition, it is less porous than thermoplastic elastomers (TPE), making it easier to clean and wash without much effort.

Chemically inert

Silicone has better anti-allergenic properties than silicone. It does not cause any chemical reactions with human skin even at higher temperatures and is considered one of the safest materials for making sex dolls.

Disadvantages of silicone

The most significant disadvantage of silicone sex dolls is that they are much more expensive than TPE dolls. Prices for high-end silicone dolls start at $2,500 and can go up to $10,000 or more.

Silicone is not as flexible or soft as thermoplastic elastomers. When you shake your doll back and forth, her hips and breasts will not shake or jiggle as much as a TPE doll would, without causing any wear and tear on the material. For most lovers, it makes no difference, but many have a fetish for shaking their hips and boobs.

TPE or Silicone: Which Doll to Choose

Now that you know the pros and cons of each material, the final choice is yours to make and only yours. Sex is a highly personalized experience and your individual preferences dictate the decision whether to for a Silicone Doll or a TPE.

If you’re still confused about which material to buy, consider the below scenarios:

What’s Your Budget?

The biggest obstacle for most sex doll lovers is budgetary constraints since lifelike TPE or Silicone sex dolls are expensive. If you’re low on budget, say $2000 or less, then a TPE sex doll might be the viable option but if you’re willing to spend around $3000 or more, then you can have a high-end Silicone doll in your bedroom.

Do you Love to Have Hot Baths with your Cute Little Partner?
TPE cannot withstand high temperatures but Silicone can. So, if you have a fantasy for enjoying hot baths with your doll, then a Silicone doll is a more preferable option.

Regardless of which material you choose, you’ll get a committed, beautiful, and hyper-realistic sex doll in your room that is always ready to fulfill all your sexual needs and fantasies.
