TPE composition and variations for sex dolls

TPE (Thermoplastic Elastomer) is a mix of plastics and rubber that is used for the production of sex dolls and torsos, among other things. The material is known for its softness, flexibility and skin-like texture.

Composition of TPE

There is no set recipe for TPE, as different brands have their own formulas. In general, TPE consists of:

• Thermoplastic polymers (such as SEBS – Styrene-Ethylene-Butylene-Styrene)
• Oils (usually mineral oil to increase softness and elasticity)
• Fillers (such as silica or talc to regulate firmness)
• Additives (for color, UV resistance and antibacterial properties)

Why is there no set recipe?

• Manufacturers optimize their TPE blend for various properties such as softness, odor, durability and ease of maintenance.
• Cheaper TPE dolls can hold more oil, causing them to become sticky or leak oil more quickly.
• Higher quality TPE has a better balance of softness and durability and feels more realistic. Also, more expensive formulas often have properties that make the doll more durable

If you want to buy a TPE sex doll, it is wise to look at the quality of the material, as there can be major differences between brands.

TPE is not a fixed compound that is the same everywhere, a cheap TPE sex doll is often soft and contains more oil, which causes it to wear out faster.

A better quality formula for TPE contains better ingredients that ensure longer lasting use.

TPE from one sex doll brand is therefore not the same as that of another brand. Just as car tires differ in quality per brand, despite the fact that it is always rubber, the price range of sex dolls often depends on the quality.
