The choice of materials in sex dolls significantly impacts their realism, durability, and maintenance. At conventions, manufacturers showcase dolls made from various substances, each with unique advantages and considerations. Silicone is renowned for its lifelike texture and flexibility, providing a realistic skin feel and a natural appearance. It is also resistant to heat and UV rays, making it relatively durable with proper care. TPE (thermoplastic elastomer), on the other hand, is softer and more elastic, offering a more lifelike feel at a lower cost. However, TPE is porous, which can pose challenges for cleaning and hygiene. Some manufacturers experiment with hybrid materials that combine silicone’s realism with the flexibility of TPE, aiming to offer the best of both worlds. There are also emerging eco-friendly options, such as bio-based silicones, which focus on sustainability without compromising quality. When comparing these materials at conventions, attendees can physically examine the dolls, ask questions about maintenance, and assess their suitability based on personal preferences. Understanding the differences helps consumers make informed choices aligned with their needs, whether for realism, longevity, or environmental considerations.
