Silicone and TPE are the two primary materials used in sex doll manufacturing, each offering unique qualities that influence the doll’s look, feel, and durability. Silicone is prized for its high realism, hypoallergenic properties, and heat resistance. It provides a smooth, firm texture that closely resembles human skin and maintains its shape over time. Its non-porous nature makes it easier to clean and less prone to staining. However, silicone tends to be more rigid than TPE, which can affect flexibility. TPE, on the other hand, is a softer, more elastic material that offers exceptional flexibility and a more skin-like feel. It is also more affordable and easier to mold, allowing for intricate details and a realistic tactile experience. TPE is porous, which can pose challenges in cleaning and maintenance but can be managed with proper care. Both materials are mixed with additives to enhance durability, elasticity, and appearance. The choice between silicone and TPE depends on the desired balance of realism, flexibility, maintenance, and budget. Skilled manufacturers carefully select and process these materials to produce sex dolls that meet high standards of realism, durability, and user satisfaction.
