Hybrid sex dolls are crafted from a combination of materials designed to maximize realism, durability, and safety. The most common materials include silicone and thermoplastic elastomer (TPE). Silicone is prized for its realistic feel, heat resistance, and hypoallergenic properties. It retains shape well and is easy to clean, making it a popular choice. TPE, on the other hand, offers a softer, more flexible texture that closely mimics human skin, often resulting in a more lifelike experience. However, TPE requires more careful maintenance to prevent damage and bacterial growth. Internal frameworks typically consist of metal or high-strength plastics, providing structural support and articulation for realistic movement. Some hybrid dolls incorporate layered materials, with a rigid core for stability and softer outer layers for tactile comfort. Additionally, advanced models may include heating elements, sound modules, or internal sensors to enhance sensory responses. Understanding these materials helps users make informed decisions about maintenance, longevity, and safety, ensuring their investment provides a satisfying and hygienic experience.
