What Material Do They Use for Sex Dolls?

What are sex dolls made of? Here’s a quick rundown of the most common materials before getting into deeper detail:

Sex dolls are made of:

  • Silicone 
  • TPE (Thermoplastic Elastomer) 
  • Rubber 
  • Latex 
  • Plastic 
  • Foam 
  • Fabric 

We’re going to shoot straight with you and tell you right off the bat that silicone and TPE are the best materials. That’s not just us saying that.

Men all over the world love these materials because they’re realistic in look, feel, and reaction to heat and physical pressure.

Since most of this post is going to dive deeper into why TPE and silicone adult sex dolls are the best, we’ll use the rest of this section to talk about the other materials. 

What material do they use for sex dolls other than TPE and silicone? This leaves us with rubber, latex and the other materials: while not as good and pricey, still have a legitimate place in the adult sex dolls industry.

  • Rubber isn’t used too often for adult sex dolls; since, it’s porous – meaning that it can harbor bacteria, and it can sometimes latch to your skin. You’ll often find this material used for dildos and butt plugs more often than sex dolls. The biggest benefit is that it’s affordable. Also, to mention, rubber can be used with inflatable adult sex dolls.
  • Latex is very common for adult sex dolls, but not for the ultra-realistic ones. This is typically used for the inflatable variety. While inflatable adult sex dolls have come a long way and look far better than they did decades ago, most men only get them because they are easy to hide and cheaper than almost any other sex toy.
  • Plastic is smooth and hard, giving some men a firmer sensation; while not entirely realistic, it can definitely be satisfying. Not only that, but plastic adult sex dolls tend to be affordable.
  • On the other side of the spectrum is fabric. These are like large plush toys with a sexy, naughty side to them. These let you do the nasty with a pillow in a way that’s much more satisfying. There are many sexy printings and shapes that can be found with fabric.
  • Lastly, we have foam. Polyurethane foam sex dolls are surprisingly high-end and very good, but they can be expensive and aren’t great around water.

These foam sex dolls tend to come in parts, which might be a little macabre for some men. There are also very cheap foam adult sex dolls that provide some sensation, but mostly exist because they are extremely affordable. 

TPE Sex Dolls – What is TPE Material?

Without throwing too much science at you, let’s answer the question of what is TPE? TPE material is a type of copolymer that mixes plastics and rubbers together into an entirely unique material that shares the characteristics and advantages of both base materials.

TPE has enhanced longevity with the added bonus of returning to its original shape after stretching, which is an ideal characteristic for adult sex dolls. 

So in short, what is TPE material? It’s a combination of rubber and plastic. There are several other questions about TPE.

Is TPE safe?

TPE adult sex dolls are generally safe, but the truth is that TPE hasn’t been studied too much in this regard. So when it comes to the question of is TPE safe, the answer is that it should be, but only buy from reputable sellers just to be sure. 

That’s great and all, but when most men search for “what is TPE,” what they really want to know is why TPE sex dolls are amazing. We’re getting to that. 

A TPE sex doll is similar to silicone sex dolls but more affordable. They are realistic to the eyes and hands, have smooth textures. They are surprisingly hypoallergenic and work with both water-based and silicone lubricants. It can take somewhat higher temperatures but can melt if too hot. 

The downside to a TPE sex doll is that it’s porous and spongy, so make sure to clean it thoroughly after each use: also, quality can be inconsistent. It depends on how well the TPE was blended.

You’ll also want to powder this adult sex doll regularly because the rubber in it can make the doll sticky. 


  • TPE is realistic and relatively affordable 
  • Have smooth textures and work with both water-based and silicone-based lubes 
  • TPE adult sex dolls are porous, so clean them thoroughly 
  • Quality can be inconsistent, so only buy from good brands

Silicone Sex Dolls – What is Silicone?

You know about TPE material, so now you’re probably asking what is silicone? Good question. Like before, let’s start with the science part and then move into the more intimate details.

Silicone is a polymer, meaning that it has a repeating chain of large molecules. The majority of silicone is composed of silicon and oxygen atoms with some hydrogen and carbon here and there. 

Now with the science part out of the way, let’s answer the question of what is silicone and why are silicone sex dolls so prized? You’ll find that silicone sex dolls have many of the advantages of TPE ones.

They are…

  • Hypoallergenic
  • Incredibly realistic to the eyes and hands
  • Can retain high temperatures
  • Highly detailed. 

Silicone can withstand higher temperatures than TPE and the dolls are even more realistic. An added bonus is that silicone is non-porous, so it’s less likely to harbor bacteria.

On the other hand, silicone is much more expensive, is often less durable than TPE and can be denser to the touch.

Be sure to only use water-based lubricants with silicone dolls. Silicone-based lubricants will weaken the molecular bond of your doll, meaning the material will wear out much faster than it would normally. 


  • Silicone creates the most realistic looking adult sex dolls possible 
  • More resistant to high temperatures than TPE 
  • Can be dense to the touch, which may or may not be good depending on your preferences 
  • Only use water-based lubes with these adult sex dolls 

Silicone vs TPE – Which Should You Choose?

When it comes to silicone vs TPE adult sex dolls, it’s like comparing a green apple to a red one.

They both have similar benefits, look and feel realistic and are often prized as the best adult sex dolls on the market. With that being said, there are a few key differences to be aware of that will help you decide on the right doll for your needs.

TPE vs. Silicone:

  • Let’s start with one important factor that plagues every consumer: price. You want a realistic adult sex doll, but you definitely don’t want to spend as much as you would on a real woman. TPE wins here because it’s more affordable
  • With that being said, you should know that the gap in price between TPE and silicone isn’t as large as it used to be. The two keep getting closer with silicone prices dropping, so don’t automatically choose TPE thinking you’ll save a massive amount. You might, but it’s worth looking into both before entering those credit card numbers. 
  • Both are realistic to the touch, but which one is more realistic? Silicone is sticky by nature and needs to be powdered down to remain smooth. The same can be said of TPE, especially if the blend has more rubber. Some people think that TPE feels more realistic while others side with silicone, so this is a difficult one to judge. 
  • In general, TPE reacts to pressure more realistically than silicone. That’s because silicone tends to be more dense, but you might like that as it gives you more resistance.
  • TPE also tends to be more flexible, which in the battle of TPE vs silicone gives it some major points. 
  • When it comes to temperature, silicone will win each and every time. Both can take cool and warm temperatures, but TPE starts melting as the mercury rises. Silicone doesn’t melt, making this ideal if you like it hot. On the other hand, this makes silicone much harder to recycle, but you probably aren’t worried about that.

TPE vs silicone is a toss-up because both are great, so it’s up to you to choose which benefits you want in your adult sex dolls. 


  • TPE is softer, more flexible and tends to be less sticky 
  • Silicone tends to have more realistic molds and shapes 
  • TPE is more affordable 
  • Silicone has no problems with high temperatures while TPE might melt 

What Does Sex With Adult Sex Dolls Feel Like?

Don’t be embarrassed to ask this question, everyone wants to know what it’s like to be with adult sex dolls. In general, adult sex dolls are nearly as good as real women. Some men actually prefer it because you get to control the entire affair. 

Let’s start with the small stuff and work up to the real event. What does it feel like to kiss and touch adult sex dolls? If you powdered it properly, then adult sex dolls feel very realistic and it’s just like touching a real woman. The face also tends to be realistic with yielding lips that love to be kissed. 

Oral sex is the one place where you may notice a difference between adult sex dolls and women. With a good amount of lube and some heat, they are close to realistic. It’s pleasurable, but you won’t get the suction like from a real mouth. 

Where adult sex dolls excel is anal and vaginal sex. With the right amount of lube and heat, you won’t be able to tell the difference between a woman and the doll. The parts are molded from real women and you can really feel it.


  • With the right amount of powder, the body will feel like real skin 
  • Kissing feels great and realistic 
  • Oral sex is good, but some men might miss the suction of a real mouth 
  • Vaginal and anal sex are spot on and feel like the real thing 

Can You Take a bath with Adult Sex Dolls?

You can conditionally bring both TPE and silicone adult sex dolls into the bath with you, but it depends on the water temperature. If the water is cool to lukewarm, then both materials will be just fine. In fact, a fun romp in lukewarm water can be very enjoyable. 

If you want to heat things up with a steamy shower, then you’ll want to keep TPE dolls out of it. TPE might melt in hot water, but silicone will be just fine. Turn the temperature up as high as possible and the silicone won’t suffer in the slightest, just watch out for your own skin.

Making Your Decision

Which one of the adult sex dolls reigns supreme? As stated above, you’re comparing two very similar types of adult sex dolls with only slight differences. 

This is how you can decide:

  • If you want softer skin, a flexible body, and an affordable toy, then TPE adult sex dolls are your best bet.
  • If you don’t mind spending the extra money for an even more realistic toy and don’t mind it being a little denser, then silicone adult sex dolls will fit your needs much better.

Both of these adult sex dolls are amazing, so you’ll be good regardless of your choice. It all comes down to what your preferences are and which one suits your needs better. In either case, they’ll feel great and you’ll get a good night of pleasure from them.
