The materials used in sex dolls are carefully selected to achieve realism, durability, and safety. The most common materials are silicone and thermoplastic elastomers (TPE). Silicone is prized for its realistic feel, resistance to heat and chemicals, and long-lasting qualities. It offers a firm yet soft texture that closely resembles human skin. Silicone dolls often have a more detailed appearance, with options for translucency and pigmentation that mimic natural skin tones.
Thermoplastic elastomers are softer and more flexible than silicone, making them ideal for creating more affordable dolls that still provide a realistic tactile experience. TPE is also hypoallergenic and easy to repair or customize, which adds to its appeal. However, it tends to be less durable and more porous than silicone, requiring diligent cleaning.
Internal structures are typically made of metal or plastic, forming skeletons that allow movement and poseability. Some dolls incorporate embedded systems or heating elements to simulate body warmth, further enhancing realism. Additional materials, such as synthetic hair, are used for wigs, and painted details like eyebrows, eyelashes, and lips are applied using special pigments designed to withstand cleaning.
Overall, the choice of materials balances realism, safety, and cost, with high-end dolls leaning toward silicone for their lifelike qualities, while TPE offers a more budget-friendly alternative. The combination of these materials results in highly realistic and customizable dolls tailored to individual preferences.
