TPE Sex Doll vs Silicone Sex Doll - What's the Difference?

Silicone and TPE are the most prevalent materials utilized in the production of sex dolls, and both touches comfortable and realistic.

TPE dolls are more durable and resistant to wear and tear. They are easier and more convenient to clean and keep fresh. Silicone dolls are likely to be more realistic in appearance and touch, because the material is similar to lifelike human skin. They can be heated for much longer,we can provide heat systems for our silicone dolls. 

1. What is a TPE sex doll?

TPE, often called thermoplastic rubbers, belongs to a category of copolymers or is a physical blend of polymers, typically a combination of plastic and rubber. It has both thermoplastic and elastomeric characteristics. TPE is widely used in the automotive and household appliances industries. In fact, you may well have items at home made from TPE. 

Thanks to its flexibility, moldability, and soft texture, TPE becomes an excellent choice for manufacturing realistic sex dolls at a reasonable and affordable cost. 

2.  Pros & Cons of TPE sex dolls

Pros: 

1) Affordable

When manufacturing TPE sex dolls, two components are combined, namely a thermoplastic and an elastomer. As these materials are highly suitable for injection molding, mass production can be carried out efficiently and on a large scale.Thus, the cost can be reduced, making the dolls more affordable. The price of a TPE sex doll can range anywhere from $800 to $3,000. 

2) Soft

Because TPE is a mixture of thermoplastics and elastomers, the features of these materials can be modified to achieve the desired texture. The manufacturer has developed a soft and stretchy blend that offers an extremely realistic feel. Hence, it is softer in comparison to silicone. 

3) Flexible

Given the excellent properties of TPE, the breasts and hips will naturally jiggle and shift as the doll moves back and forth. As for sexual positions, the TPE is more elastic, which makes the doll more flexible. This enables the doll to accommodate a wider variety of sexual positions. 

4) Stable

Thanks to the state-of-the-art technology, certain modern sex dolls are outfitted with heated sensors that can mimic the temperature of real human skin. This feature is designed to enhance the user's experience by providing a more realistic and immersive interaction, as the dolls can maintain a temperature similar to that of a human body, thus making the experience feel more lifelike. 

5) Safe

The TPE material is safe enough for everyone because it does not contain harmful chemicals that could lead to allergic reactions. Just kiss your sex doll and hug her at ease. 

Cons:

1) More Sensitive to Stains

TPE has a high absorptive nature, which makes it prone to staining. We suggest that you dress your TPE sex doll in non-color or light-colored clothing rather than using dark materials. 

2) Regular Maintenance

For the sake of your health and the doll's durability, it is necessary to perform frequent maintenance on TPE sex dolls,such as the mouth, anus, and vagina after use. If not, the doll may become stained, develop mold, and eventually lose its shape, strength, and attractive appearance. 

3) More Sensitive to Heat

TPE can effectively retain heat, thus maintaining a lifelike quality. However, it may start to lose its consistency or even melt when the temperature exceeds 104º Fahrenheit (40ºC). Be sure to keep your sex doll away from heat sources.

3. What is a silicone sex doll?

Silicone, also known as polysiloxane, is a mixture of silicon polymer with carbon, hydrogen, and oxygen. It's chemically inert, resistant to water and oxidation, and stable at both high and low temperatures. So, it's used in many commercial applications, like lubricating greases, electrical-wire insulation, and biomedical implants. That's why the sex toy and sex doll industry has been using silicone for years. Generally, silicone sex dolls are more expensive than TPE dolls on the market. 

4. Pros and Cons of silicone sex dolls

Pros: 

1)Hyper Realistic Appearance

Silicone sex dolls usually have a more lifelike appearance, providing an outstandingly realistic look and feel. For those who want an ultra-real sensory experience, our high-quality dolls come with enhanced skin texture, including lifelike details like veins and freckles. 

2)Weight Reduction

In the current market, almost all silicone manufacturers claim to have reduced the weight of their silicone dolls. One of them said a 172cm doll weighs only 36 kg. But this information led to a crisis in 2018. In fact, all silicone dolls are 10% heavier than TPE dolls. 

As for our dolls, they are 25-30% lighter than before and 15-20% lighter than TPE dolls. For instance, the best-selling 160bb is 28 kg, the 162 is 32 kg, and the largest in the market, 170, is 41 kg. Lighter weight means easier handling during use and more flexibility for different poses. 

3)More Durable

Two factors affect a doll's durability: resilience and tear resistance. The latest platinum silicone we use is different from most materials on the market. It's a bit less soft to improve resilience and tear resistance. There was a risk during delivery that dolls might get dents in bad shipping conditions. But with this silicone, that's no longer an issue. Also, when lying on a hard floor for a long time, the butt of other dolls would sink and not return to its original shape, but ours will bounce back within 90 minutes, usually 30-45 minutes. 

4)Low Maintenance

Silicone sex dolls are easier to clean and sanitize compared to TPE sex dolls. They can be sterilized without worrying that the liquid will penetrate the skin and cause damage. They can maintain their shape better and require less maintenance because of their stain-resistant skin and incompressible nature. However, don't forget to clean the anus and vagina after use. 

Cons: 

1) Higher Cost

Generally, the cost of silicone sex dolls is greater than that of TPE dolls. 

2)Lower Flexibility

Compared with TPE, silicone sex dolls have less flexibility. You may find it difficult to move some rigid parts of their arms and legs freely. 

3)Low Elasticity

Silicone sex dolls are stiffer and harder than TPE dolls. When you move the doll back and forth, the buttocks and breasts will not jiggle.

When you’re ready to purchase a sex doll, you are likely to face the dilemma of choosing a doll with a fixed vagina or a removable vagina. (Note: if your purchase is for business purposes, we recommend choosing a removable style, which makes it easier for quick and thorough cleaning.)

So this guide will probably help you better understand the sex doll vagina and make a more informed decision.

Fixed vagina

Sex doll Vagina is usually divided into two categories: removable vagina and built-in vagina (also known as fixed vagina). The removable vagina has a sleeve-like insert,which can be easily put into or taken out of the private parts.The built-in vagina is none-detachable and permanent, resembling a genuine woman. It is very tight and textured,refreshing  you with much level of delight and energy.

To Built-in Vagina or to Removable vagina ultimately depends on your personal preference. Now let's have a brief discussion regarding the potential pros and cons of built-in(fixed) vagina and removable vagina.

Fixed Vagina

Pros

1. Offer More Realism: the fixed vagina has a soft spiral that can stimulate your penis to immerse in ecstasy with your love doll. It brings a more realistic feel because it is initially designed to closely imitate the anatomy of a real woman.
2. Use Easily: compared to a removable vagina, a fixed vagina is much easier to use. The reason is that you have no need to install or remove anything.

Cons

1. Difficult to Clean: you have to carry the doll around with you to clean the vagina after use. But if your love doll is heavy and large, you will feel worse. Also, it will take up your more time.
2. More to Spend: the doll is probably old or damaged after used many times. Of course, you will not have so great experience as used to be. So you want to replace it, but it is not permitted to only substitute the vagina. So you will have to spend a lot of money to get a totally new premium sex doll.

Removable Vagina

Prons

1. Easy to Clean: because the insert is detachable, it can be easily removed to clean for the sake of hygiene. Just gently wash it in clean water and turning it inside out to dry.
2. Cheaper and More Durable: if the removable vagina becomes old or broken, it can be cheaper and easier to buy a new one to replace without purchasing a new doll.
3. More Versatile: if the insert is damaged or worn out, you can purchase a lot of different types of replaceable removable vaginas, which brings your doll new features and you versatile sensual experiences at a very affordable price!

Cons

1. Less Realistic Sensation: due to the removability of the vagina insert, it may slide a little when you make love with your doll, which influences genuine sensation to some extent.
2. More prone to damage. You may damage the sex doll when you insert or remove the inserts.
3. Inserting the vagina into a sex doll needs skill.

But how can you help your doll to use this position?

First,have your love doll lie on her back.Carefully raise her left leg towards the ceiling at a 90-degree angle and then push her left leg to the left slowly and gently ; then place her right leg on the right in the same manner. Your doll's vaginal hole will now be open enough to accommodate the insertion.

3. Apply Talcum Powder to Doll's Vaginal Opening and Removable Vagina

Apply a thin layer of talcum powder to the outer surface of the detachable vagina and the inside of the vaginal opening. The talcum powder will help the insert to slide easily and smoothly into the hole and will also clean your sex doll.

When purchasing a sex doll for the first time, you might come across the standing feet option. You may be curious about what exactly it is, how to utilize it correctly, or whether you should need it. This guide will explain the standing feet option in details.

What is the standing feet option?

Standing foot option refers to use special device which can make the doll stand upright.

Because of the softness of TPE material, the doll with regular feet cannot stand up. Otherwise, the skeleton inside the footboard may directly break or penetrate the soles of the doll’s feet.

With the standing feet option, three small metal bolt heads protrude slightly from the bottom of the foot as an extension of the skeleton to support the doll’s standing. In this way, the doll can stand l for long periods of time for photography, intimacy or storage. However, we recommend not leaving your doll free-standing whilst unsupervised as he/she may fall and become damaged (unless correctly supported).

Thanks to the advanced technology, robust bolt-free standing inside the skeleton can support the doll without exposure to the metal bolt heads. It is not only beautiful but also utilitarian.

Pros

Photography

Dressing your doll.

Easy to clean your doll.

Convenient to move.

Store your doll upright at home.

People with a shoe fetish who want their doll to stand in shoes.

Make love with sex doll whilst standing.

Cons

Bare bolts are exposed to those who like foot fetish.

Inflexible (foot cannot move upward or side to side - only down)

How to Use Standing Function Correctly

Unlike real people, sex dolls cannot have a cerebellum to function body balance. The three metal bolt heads at the bottom only serves as a supporting role, which cannot guarantee well-balanced. So the doll needs some firm things to rely on,such as a wall. Although it takes you more time, it is convenient for you to constantly adjust the angles to find the best posture.

When the doll stands barefoot on the ground, you’d better put a soft cloth on the sole of the foot. When you wear shoes for the doll, wear a few more socks or use a hard insole can prevent the shoes from being damaged.

 FAQS

Q: Is the standing foot larger or flatter than the normal foot?

A: No, it's the same foot.The standing feet are the same as the regular feet(non-standing feet), but the ankles have been redesigned and the soles of the feet have been reinforced, which let all dolls with the standing feet option stand on their own.

Q: Can the standing foot still wear high heel shoes?

A: High heel shoes can be worn on the foot but only flat shoes are recommended for standing. If heels are used we recommend leaning the doll on a support and ensure it is well-balanced.

Q: Which dolls are offered with the standing foot?

A: All dolls can be ordered with standing feet, except torsos.

Q: Is the standing feet option is available for all dolls?

A: It is only available for dolls over 100cm.

Q:Should you buy the standing feet option?

If you need the doll to make love whilst standing, employ the doll as a photography model, or store the doll at home, it is highly recommended to choose the standing feet option or bolt-free standing feet option.

Most doll brands provide two types of skeletons for you to choose from.

Standard skeletons can actually satisfy general needs and engage in basic movements. 

Upgraded skeletons(Double-jointed Skeleton) have a more complex and sophisticated design. Inside the doll, a super flexible stainless steel skeleton simulates real human joints. Double-jointed elbows, and palm ball joints allow for a wide range of natural and lifelike poses, such as missionary and doggy style. Also, the adjustable waist joint ensures stable and dynamic postures, making the dolls even more versatile.Whatever position you prefer, she is ready to follow! 

Customers are allowed to choose between the traditional standard skeleton and more advanced double-jointed skeleton, ensuring their personalized experience and unique taste.

The articulated hand skeleton can imitate the movements and postures of a human hand. Especially, the upgraded version is more realistic and practical. The new-generation ball bearing design and the spring tension-based system easily enable the fingers to move to the desired positions. 

This new hand skeleton design is creative and impressive, including damping structures and spherical structures, which can enhance flexibility, realism and durability. 

Damping structures are set inside the joints that connect each phalanx to imitate the actual movement of finger joints. It also solves the problem of joint breakage and ensure wear-resistant use and a long service life. Each finger joint is equipped with a soft rebound spring, allowing you to place your fingers in any appropriate shape and providing a better tactile experience. 

The bottom finger joints and hand joints are connected by spherical structures. Tightening the tension spring will create a definite frictional resistance between the ball head and the spherical groove. This can not only fix the fingers in appropriate positions but also enable multi-directional rotations of the finger joints and wrist joints. 

This upgraded hand skeleton is mainly composed of wear-resistant and recyclable steel materials. It is designed with more stable joints that can better maintain their positions and won't become loose or flabby over time. It is used for both TPE dolls and silicone dolls, and can imitate finger movements more realistically and flexibly.

One of the most significant features of sex dolls is body heating. Before this innovation, many love doll fans passion are often undermined by the chilly texture of the doll's skin, especially in winter. Some even carry them beside a fireplace when they wanna have sex with the love doll. Now the inner-heating option can provide warmth almost instantly, making passionate interactions more comfortable and cozy. This characteristic greatly amplifies the overall experience, making the doll feel more like a vivid and emotional companion. 

When you cuddle your partner in sofa or bed, there's this indescribable warmth you feel inside your chest.As soon as you feel it, you know that nothing can replace it. And you'll never be able to feel like this or recreate it with just yourself. No other warm comes close to this. 

It is as suffusing, enveloping, swelling, blooming. It's warm, it's protective,and it's intimate. It's a warmth that surges through the spirit and washes over the body, it's a warmth that expands from the heart and overwhelms one's sorrow. 

It's a feeling of belonging with and to someone and somewhere, it's the feeling of home. It's the feeling of fitting somewhere, of finding your place in the world. It's like holding all the value in the world right between your arms, close to your heart.

Notes:

1. In order not damage the doll’s material, the charging time should not exceed 30 minutes. If the desired temperature is not reached, pause for a while and then restart the heating.
2. Most manufacturers will not provide guarantees for the internal heating systems.
3. Thicker areas such as vaginal, breasts and ass cannot be heat up. So the temperature of different parts of the body varies.
4. Do not carry the sex doll when heating and switch off the power before using it.
5. Try not to make the doll move drastically after heating.
6. The heating function only mimics the temperature of human being , constant temperature effect of a real person cannot be desired.
7. The heating system of many dolls can not co-exist with the gel breasts, breathing system, or auto-sucking function.
