Introduction and applications of TPE and silicone material

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.

They differ 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.

They differ 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 sex dolls.
