In-Depth Analysis of TPE and Silicone Sex Dolls

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

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

What are the differences between TPE and Silicone sex dolls?

1. Difference in elasticity

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

2. They differ in analytical structure

Silicone is the backbone of the oxygen-bonded elastomer, and the side chain is usually methyl, which corresponds 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, the silicone doll is more durable than the TPE love doll.

3. Processing performance differs

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

4. High temperature resistance difference

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

5. Cost difference

The price of silica gel is usually above US$5,000, while the average price of TPE is between US$2,000 and US$5,000. The price of TPE is more dominant, except for special materials such as halogen-free flame retardant, food grade, etc. So you can buy sex dolls at the best price.

6. Difference in environmental friendliness

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

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

Both have their own advantages, but TPE is cheaper in terms of processability, recycling and cost than silicone. As TPE is increasingly used and used, TPE is the preferred material to replace silicone! While TPE vs silicone, TPE is definitely more suitable for making sex dolls.
