Adult solid sex dolls have huge following groups all over the world, including artists, celebrities, workers and many other groups of different professions. Especially during the COVID-19, the sales of lifelike adult sex dolls have risen sharply, and many new customers have appeared.

Maybe they have done some product research before buying sex dolls. But they are still skeptical about the use of adult sex dolls. For example, they are worried that using adult sex dolls will cause harm to the human body.

It is very correct to ask such a question. When you buy a product that has intimate contact with your private parts, shouldn't you consider product safety? More importantly, it is almost a nightmare to cause permanent damage to the genitals by having sex with sex dolls.

Many people don’t even know what materials are used to make physical dolls? What is the use? It happens that many customers have asked this question, so we wrote this article to eliminate customers' doubts and let customers buy sex dolls with confidence.

What material is the lifelike adult sex doll made of?

Initially, the materials used for production sex doll were silicone and PVC. Due to the insufficient material properties of PVC itself, additives are often added in actual use, such as DEHP, which is harmful to the human body.

Therefore, Europe, Japan, South Korea and other countries have imposed restrictions on products using PVC as raw materials. Finally, PVC withdrew from the sex doll market and was replaced by TPE.

Note:

PVC is a kind of hard plastic. To make it soft, a large amount of plasticizer must be added. The plasticizer is easily released in a heated environment. If DEHP is used, it will interfere with human body secretion, causing breast cancer in women, birth defects in newborns, reduction in male sperm count, and even mental illness.

Nowadays, adult love dolls are mainly made of silicone and TPE materials. According to materials, adult sex dolls can be divided into silicone sex dolls and TPE sex dolls.

TPE And Silicone

TPE, sometimes called thermoplastic rubbers, is a type of copolymer or a mixture of polymers (usually plastic and rubber), composed of materials with thermoplastic and elastomer characteristics.

Silicone, sometimes called silicic acid gel, is a highly active adsorption material, which is an amorphous substance. It is a thermosetting rubber. It will not melt when heated after vulcanization. It will burn when the temperature is too high. The products of complete combustion are water and silica.

The difference between TPE and silicone

1) Tension. TPE has good elasticity at room temperature, and it will be permanently deformed if the force exceeds the limit. Silicone is a thermosetting rubber, it will not melt when heated after vulcanization, it will burn if the temperature is too high, and it will not deform.

2) Molecular structure. One is the SI02 structure, and the other is the CC structure.

3) Processing performance. Silicone needs to be vulcanized and heated for molding, while TPE can be processed and molded without vulcanization. Silicone processing is difficult to form, while TPE production and processing are simple.

4) Heat resistance. Silica gel: between 200 degrees and 300 degrees, while TPE: 130-150 degrees Celsius, the temperature is higher, it will aging and cracking. For adult sex dolls, higher heat resistance means more durability and higher cost.

5) Price. Because TPE has low processing cost, can be recycled, and two-shot injection molding, TPE has an advantage in price.

6) Cost. The waste of silicone cannot be recycled, and the waste of TPE can be completely recycled and reused. TPE can save more costs.

7) Use experience. The silicone sex doll has a delicate face and is more realistic. TPE sex dolls feel softer to the touch.

Are they safe for the human body? Yes it is

Both TPE and silicone are environmentally friendly and non-toxic materials, which will not cause any harm or irritation to human skin.

TPE

Styrene polymer elastomer and process oil are the main components of TPE. Those who are familiar with TPE material processing must know that these ingredients are environmentally friendly and non-toxic.

There will be no DEHP, PAH, NP, bisphenol A, heavy metal substances during processing. It fully complies with ROHS, REACH, EN71, PAHS and FDA environmental tests.

Silicone

Silicone meets FDA and EU LFGB testing standards. Many cooking utensils, especially bakeware and kitchen utensils, are made of silicone.

Additives

In order to obtain a realistic effect close to the human body when producing love dolls, some toners, compatibilizers and flavoring agents are usually added to adjust the color or smell of the material.

Toner

Since lifelike sex dolls are in close contact with the human body, sex doll manufacturers use non-toxic and harmless toner.

Industrial flavors

Industrial flavors include natural flavors and artificial flavors. Due to the high cost of natural flavors, many small workshops use chemically synthesized artificial flavors, which have a stronger fragrance, and there is no guarantee that they will not cause any side effects or harm to the human body.

Therefore, when buying lifelike adult sex dolls, be sure to look for top brand manufacturers or agents. Top brand manufacturers use natural flavors that are environmentally friendly and non-toxic.

In short, a lifelike sex doll with a small smell and a comfortable smell should have the following conditions.

• High-quality operating oil
• high-quality colorants
• natural flavors

Finally

Although the material of the sex doll itself is harmless to the human body, if you are using the sex doll, be sure to clean the sex doll after each use and keep it tidy.

This is because TPE and silicone are porous materials, and bacteria

and fungi may enter these pores and form colonies. If you do not clean and take care of it in time, you will get some diseases over time.
