Silicone and thermoplastic elastomer (TPE) are the two prevailing materials for real-feel sex dolls, each with advantages and trade-offs. Silicone is renowned for durability, color stability, and resistance to wear. It tends to hold its shape over time, withstand heat better, and clean up with relative ease, making it a practical long-term option. TPE, on the other hand, offers a softer, more elastic texture that many find closer to real skin. It’s typically more affordable and lighter, which can be appealing for first-time buyers or those seeking cost efficiency. However, TPE is more porous, requiring meticulous cleaning and drying to prevent odor or mold, and it may degrade with improper handling or exposure to oils and certain cleaners. In addition, silicone often carries a higher upfront price but lower ongoing maintenance costs, whereas TPE’s cost advantage can be offset by more frequent care and potential replacement intervals. Temperature tolerance also differs: silicone remains stable under a wider range of conditions, while TPE can be more sensitive to heat and prolonged sun exposure. When choosing between them, consider your budget, maintenance willingness, desired lifespan, and the level of realism you seek. Both materials can deliver satisfying experiences when cared for properly.
