TPE VS. SILICONE: A Comprehensive Guide

When you find yourself in the market for a sex doll or a love doll, one of the first decisions you will have to make is which material you want your doll to be made of. Two of the most popular materials used for sex dolls today are silicone and TPE. Both of these materials are usually the most sought after because the dolls made from these materials not only look incredibly realistic but they provide you with next-to-real sensation. However, knowing the pros and cons of both of them can guide you in making the right decision that will meet your needs.

For most sex doll players, one of the hardest decisions before ordering a realistic sex doll is to consider the material of the sex doll, especially for new buyers. In this blog, we will relay some accurate analysis and comparison between TPE Silicone sex dolls, guiding you to make a more reasonable decision.

Silicone is plastic. It is usually hot and rubber resistant, and so has a wide variety of applications, such as lubricants, medication, glue, cooking utensils, etc. This can come in other ways, but silicone rubber is the one we see in Silicone love dolls.

Silicone rubber can be very soft and stable depending on the method of preparation and is very strong even under extreme pressure to maintain its original shape. It is also warm and clean because it does not react with most contaminants. It is commonly used in medical implants. It is very heat-resistant.

The technology of producing silicone and TPE have undergone many changes during the past few years (similar to the realistic dolls, and the techniques have been vastly improved. Silicone is a silicon rubber mixed with carbon, hydrogen, and oxygen. TPE is a thermoplastic elastomer which is a plastic and rubber mix. Let us consider both these materials on a different basis.

Which sex doll is right for you?

Currently, sex dolls are made from two different materials: TPE Silicone Sex Dolls. The materials differ in terms of production, care requirements, and feel. TPE sex dolls, for example, are softer, while dolls made of silicone are more resistant and therefore last longer. At Silicon Wives, we sell both.

Silicone vs. TPE? Well, which material is more suitable for you is purely a matter of taste. You can have perfect fun in bed with both sex doll variants.

Here you can find a summary of the advantages and disadvantages of TPE material and silicone material.

This way, you can make the right decision for choosing the suitable sex doll material.

Considerations when buying realistic sex dolls

To decide which material is best for sex dolls, you should first be clear about your expectations when you buy such a doll.

Ultimately when it’s time to buy, you’ll have to determine what material is best for you based on your needs.  Still undecided?

TPE Sex Dolls

TPE sex dolls are made from Thermoplastic Elastomer (TPE), otherwise called thermoplastic rubbers. TPE is made from the combination of rubber and plastic, and possess properties from both materials. This makes TPE dolls flexible, slip resistant and shock absorbent.  They are the most popular of dolls due to their affordability.


TPE sex dolls are a lot less expensive than silicone dolls as TPE is a less expensive material to produce while possessing almost the same characteristics. They look very real and human-like, with soft and smooth bodies that make them easy to handle. They also have the ability to retain warmth and, because of the elastic features of the TPE material, can be squeezed as you would a real human. The material is also odorless and hypoallergenic, which makes it unlikely for it to cause allergic reactions.


TPE is a more porous material than silicone, which makes it easier for fluid to become trapped which can enable germs and bacteria a chance to thrive if you do not properly clean your doll. One way to simplify the clean up process is to customize your TPE doll by selecting a removable vagina when you place your Annie’s Dollhouse order. Additionally, since TPE is a blend of materials, one manufacturer’s doll may feel slightly different from another.

Silicone Sex Dolls

Silicone sex dolls are made of silicone (no surprises here), a man-made polymer material which is rubbery, heat resistant, and available in a number of forms. It is a very versatile material with lots of properties and uses, with a wide range spanning from kitchen spatulas, baby teething rings to breast implants used in cosmetic surgery. Silicone sex dolls have been in existence for a while now, and have proven to be of the highest quality available.


Silicone sex dolls are the closest to actual human beings when it comes to sexual stimulation, and they have a very real feel when you touch them. They are slightly more durable than TPE, so your sex doll may not be as delicate. Silicone sex dolls also have the ability to retain warmth, providing you with a more human like feel. Silicone dolls are easier to sterilize because of the non-porous, silicone material, and they rarely cause allergic reactions.


Silicone sex dolls are the most expensive types of dolls because silicone is an expensive material and the technology used in its production is costly. Also, silicone dolls are heavier and slightly more rigid than TPE sex dolls, as they do not have the same ability of elasticity that TPE possesses.

Silicone has the advantages of safety and non-toxicity. It is insoluble in water and any solvent. It is non-toxic and tasteless, chemically stable and does not react with any substance except strong alkali and hydrofluoric acid. A TPE doll has high adsorption performance, good stability and stable chemical properties. It was widely used in adult products such as silicone sex dolls, and food products.

TPE is a kind of thermoplastic elastomer, which is environmentally friendly, non-toxic, easy to color, smooth and soft to the touch, and has a hardness range of 0A-120A. It is easy to process and form, does not require vulcanization processing, and can be recycled and used to reduce costs. In addition, It can be coated with PP, PE, PC, PS, ABS and other plastic materials (over molding), or it can be molded separately.

What are the differences between TPE & Silicone sex dolls?

  • Difference in elasticity

TPE is a general term for a variety of elastomeric materials that have rubber elasticity at room temperature and melt flow at high temperatures. Silicone is a kind of special rubber. It has good mechanical strength, wear resistance and high temperature resistance after cross-linking. It is a thermosetting rubber and will not melt after being vulcanized. When the temperature is too high, it will burn. The product of complete combustion are water and silicon. So the dolls made from each of them are different in elasticity.

  • Difference in the analytical structure

Silicone is the backbone of the oxygen-bonded elastomer, and the side chain is generally methyl, which refers to CH3. TPE is a thermoplastic elastomer with styrenes, olefins, and polyurethanes. The main difference between the two molecular structures is the SI02 structure and the CC structure. As you can see, silicone doll is more durable than TPE sex doll.

  • Difference in processing performance

Silicone requires vulcanization and thermoforming, and TPE can be processed without vulcanization. It is difficult to form in the processing of silica gel, and the production and processing of TPE is relatively simple.

  • Difference in high temperature resistance

Silicone has an advantage over TPE in terms of high temperature resistance. The temperature resistance of silica gel is generally between 200 and 300 degrees, while the TPE theory is generally between TPE and high temperature of 130-150 degrees Celsius.

  • Difference in cost

The price of silica gel is generally more than 5,000 US dollars, while the average TPE price is between 2000-5000 US dollars. The price of TPE is more dominant, except for special TPE materials, such as halogen-free flame retardant, food grade and so on. So you can buy sex dolls with best price.

  • Difference in environmentally friendly

Silicone waste can not be recycled, TPE waste, nozzle material, trim, etc. can be completely recycled and reused. Obviously, the TPE sex dolls are more environmentally friendly.

TPE and silicone, which is more suitable for producing sex dolls?

Both have their own advantages, but TPE costs less in terms of process ability, recycling, and cost than silicone. As TPE is more and more in type and application, TPE is the preferred material to replace silicone! While TPE vs silicone, TPE is definitely more suitable for producing female sex dolls.
