The quality and realism of UK sex dolls largely depend on the materials used in their manufacturing. The most common materials are silicone and TPE (thermoplastic elastomer), each offering distinct benefits. Silicone is renowned for its durability, heat resistance, and highly realistic feel, mimicking human skin closely. It is also hypoallergenic and easy to clean, making it a popular choice for high-end dolls. TPE, on the other hand, is softer and more elastic, providing a more lifelike texture at a generally lower cost. It is also more flexible, allowing for a greater range of movement and more natural body contours. However, TPE requires more careful maintenance, as it can be prone to tears and staining if not properly cared for. Some manufacturers incorporate internal skeletons made of metal or plastic to enhance stability and poseability. Advanced dolls may feature layered construction, combining silicone or TPE with internal support structures for increased realism and functionality. The choice of material impacts the doll’s feel, longevity, and maintenance requirements. Understanding these materials helps buyers select a product that meets their preferences for realism, durability, and ease of care.
