Silicone Adult Dolls vs. TPE Sex Dolls

What’s the Difference?

Silicone and TPE (short for “thermoplastic elastomers”) are the two types of rubbery materials that cover the bodies of sex dolls.

You’ve heard of silicone sex dolls, but there is a growing number of dolls made from a material called TPE.

Both materials have their pros and cons, and it’s essential to do your research before buying a sex doll, so you know how to care and maintain her properly.

Luckily for you, we’ve come up with a list of the advantages and disadvantages of silicone and TPE.

The main differences come down to how easy it is to clean and the cost of a doll made from either silicone or TPE.

If you want to know more about each material, Earth Erotic’s chat is available to answer any questions.

Plus, sites like The Doll Forum are full of knowledgeable love doll enthusiasts who will help guide you in your decision.

So with that, let’s dive in.

TPE Sex Dolls

This material is made from a mixture of two polymers, usually plastic and rubber. The combination of these two materials creates a product that is similar to rubber but is recyclable like plastic.

Recyclability makes TPE the more cost-effective material. It also means TPE love dolls are more eco-friendly than their silicone sex doll counterparts.

To stay true to our love of the Earth and do our part to protect the environment, all of Earth Erotic’s available dolls are TPE.


TPE sex dolls are cheaper than ones made from silicone. Depending on the quality of the doll you are interested in, they range from about $800 to $3,000.

TPE has a more lifelike feel. Dolls made from this material have more jiggle and bounce, much as a real woman would have. Their breasts and ass wiggles and moves in a realistic manner during sex.

Because TPE has more give and elasticity to it, you can place your doll in a wide range of positions to suit your fantasies. Additionally, water-based and silicone-based lubricants are compatible with dolls made from TPE.


While TPE is ideal for those who want a doll that is very lifelike and flexible, it has its drawbacks.

First and foremost, TPE stains. TPE is porous and will absorb more liquids than silicone, which means you have to be aware of dyes in her clothing, her makeup, your bedsheets, and even the furniture where she sits.

Porosity also means that dolls made from this material retain humidity, meaning more time spent cleaning and making sure your doll is completely dry after use.

Lastly, TPE does not handle heat very well. This material can only tolerate temperatures of about 104º Fahrenheit or 40º Celsius. Anything hotter than that and you’ll find your doll melting or losing her consistency.

This material’s porous nature combined with the inability to withstand hot temperatures means that TPE sex dolls can’t take hot baths or showers with you.

TPE love dolls are little high maintenance, but spending extra time maintaining her will be good bonding for both of you.

Silicone Sex Dolls

Silicone, which is the most common material that love dolls are made from, is TPE’s more expensive (and resilient) cousin.

Let’s take a look at what silicone has to offer.

First, silicone is less porous and more heat resistant. You can bathe with her without fear of her skin melting and leaving you with a Terminator-esque creature in your lap.

Silicone love dolls are easy to clean, too. Boiling water is enough to get her clean, although you still want to use antiseptic soap every few uses to prevent bacteria from building.

Unlike TPE, silicone is not as porous, so you don’t need to worry about drying her as thoroughly (but still, wipe her). Also, no need to worry about making a mess — silicone is stain-resistant.


The biggest con of silicone sex dolls is the price. The price point for love dolls made out of this material generally starts around $2,000.

Silicone is a lot denser than TPE, so her breasts and ass won’t have the same bounce or give. Not only that, but silicone is not very durable. You may find your doll’s joints and other body parts losing consistency the longer you use her.

Finally, silicone dolls are not compatible with silicone based lubricants.

The Choice is Up to You

So, in the end, when trying to decide which is better, TPE sex dolls or silicone adult dolls, it comes down to how much time and money you are willing to spend on your doll.

TPE sex dolls are more fun to touch and easier on the wallet, but you may find these high-maintenance dolls are prone to mildew if not properly taken cared for.

However, she is pricey and won’t feel as realistic as a TPE love doll.

    I had no idea there was a differnce in material, I always thought it was just silicone. Now I wonder why anyone would want to have silicone if it doesn’t feel as real… But I can see how the cleanup is a pain in the ass.
