Introduction and application of TPE and silicone materials

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

TPE is a thermoplastic elastomer, environmentally friendly, non-toxic, easy to colour, smooth and soft to the touch, with a hardness range of 0A-120A. easy to process and mould, no need to vulcanise processing, can be recycled and reduce costs. In addition, it can be covered with PP, PE, PC, PS, ABS and other plastic materials (overmoulding), or can be moulded separately.

What is the difference between TPE and 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 special kind of rubber. It has good mechanical strength, wear resistance and high temperature resistance after cross-linking. It is a thermosetting rubber and does not melt after vulcanisation. When the temperature is too high, it burns. The products of complete combustion are water and silicon. This is why the dolls made from them have different elasticity.

Resolving structural differences

Silicone is the main chain of an oxygen-bonded elastomer, the side chain is usually methyl, which refers to CH3. TPE is a thermoplastic elastomer containing styrene, olefins and polyurethane. The main differences between the two molecular structures are the SI02 structure and the CC structure. As you can see, silicone dolls are more durable than TPE sex dolls.

Differences in handling properties

Silicone requires vulcanisation and thermoforming, TPE can be processed without vulcanisation. Silicone is difficult to mould during processing, TPE is easier to produce and process.

Differences in heat resistance

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

Cost difference

The price of silicone is typically over US$5,000, while the average price of TPE is between US$2,000-5,000. TPE is more advantageous, except for special TPE materials such as halogen-free flame retardant, food grade, etc. Therefore, you can buy sex dolls at the best price.

Environmental differences

Silicone scraps are not recyclable, TPE scraps, sprues, trims etc. can be fully recycled. Obviously, TPE sex dolls are more environmentally friendly.

Which is better for sex dolls, TPE or silicone?

Both have their advantages, but TPE is lower than silicone in terms of processability, recycling and cost. With more and more types and applications of TPE, TPE is the material of choice to replace silicone! TPE is definitely more suitable for the production of sex dolls than silicone. Nowadays the dolls are high quality sex dolls can well meet our needs and fantasies can well solve our physical needs, at the same time they have various styles and types, there are Japanese sex dolls, black sex dolls, curved sex dolls, mini sex dolls and so on, we can choose what we want according to the type we like.
