TPE and Silicone Sex Dolls – What's the Difference?

When you’ve made the decision of buying a sex doll, you’re left to face one of the hardest decision which is regarding the material of the sex doll. Sex dolls are made of a variety of materials such as plastic, latex, silicone, TPE, etc. The most popular materials used for making sex dolls are TPE (Thermoplastic Elastomer) and silicone. Both of these materials have their own pros and cons and are suitable for different people depending on their different requirements.

To make your choice easy, you might ask yourself a few questions: how much would you like to spend on a sex doll; whether you want to use the doll only for sex or you want to take her into hot showers with you; whether you want the doll to be more realistic or more durable; how often are you going to use the doll; how much time can you spend on maintenance; whether you want to dress her up in nice clothes or you don’t really care; whether you want a more flexible doll or a more real-looking doll. After you have the answers to these questions, read on to know the differences between sex dolls made of TPE and silicone.

The technology manufacturing silicone and TPE have undergone many changes during the past few years and the techniques have been vastly improved. Silicone is basically a silicon rubber mixed with carbon, hydrogen, and oxygen.  TPE is a thermoplastic elastomer, which is basically plastic and rubber mixed together. Let us consider both these materials on a different basis.


TPE dolls have been gaining great popularity over the recent years, much due to their low cost. The thermoplastic elastomer is very inexpensive to produce and the sex dolls, therefore, bear a low cost. Also, this low cost doesn’t mean poor quality, so it provides an added benefit. Silicone sex dolls are expensive in comparison to the TPE ones, and therefore, only a few who are willing to spend some extra money can afford to buy silicone dolls. TPE basically provides for an inexpensive alternative to silicone sex dolls with almost the same quality as silicone.


Both TPE and silicone are soft materials, so both of them are almost similar in their degrees of realism, with only minor differences. But if we’re talking about realism and life-like feature, silicone sex dolls have an upper hand, because the silicone industry has grown and refined because of new technologies in the recent years. Silicone sex dolls have the most refined vagina and other body parts. And TPE industry is in its growing phase, so TPE sex dolls are not as well-defined as the silicone ones but still have a realistic touch to their appearance.

Porous/ Non-porous:

Silicone sex dolls are non-porous. They are easy to sterilize and thus, are very hygienic. They have no pores where any moisture or water can be trapped. TPE dolls, on the other hand, contain pores, so they cannot be sterilized. This makes it difficult to clean them and moisture stays inside the vaginal and anal cavities, which can be unhygienic and can cause infections. However, both are materials are hypoallergenic.

True-to-life sensations:

One obviously wants to have true to life sensations while having sex with love dolls. Both TPE and silicone provide different benefits regarding these sensations. Although both TPE and silicone can retain warmth silicone is less sensitive to heat. So, you can take hot showers with your silicone doll but not with a TPE doll. Both TPE and silicone are soft materials, but TPE is more elastic which makes it smoother to touch than silicone which feels rather dense to touch, and can be sticky to touch, sometimes. This elasticity makes TPE sex doll’s breasts and butts will wiggle when you have sex with it, which makes it much sexier. Also, since TPE is an elastic material, it is more flexible so you can make different positions with her.


Since silicone dolls are easy to clean and sterilize, they require very little to no maintenance. Also, silicone doesn’t stain easily. TPE is not as resistant to water, heat, stains as silicone, so it requires maintenance after regular intervals.


Silicone is said to be less durable than TPE, so TPE has an upper hand if we talk about the longevity. However, this largely depends upon the quality of material that is being used in making the doll.

To sum up, both silicone and TPE have their own pros and cons, and it can be difficult to make a choice between them while buying a sex doll. However, both TPE and silicone sex dolls come in good quality and are similar in many degrees. But different people have different preferences. Know your requirements well, and then decide which sex doll would be the best for you.
