Nearly all modern sex dolls are made from one of two material families: TPE (thermoplastic elastomer) or silicone. While listings often present this as a simple choice, the real differences involve porosity, tear strength, hygiene behavior, repairability, and long-term stability.
TPE is a flexible polymer blend known for softness and elasticity. It allows manufacturers to create very compressible body areas and is generally less expensive to produce. However, TPE is microscopically porous, which means it can absorb oils and requires more regular surface maintenance. It also benefits from periodic powdering to reduce surface tackiness.
Silicone is a chemically stable elastomer with a non-porous structure. It has higher tear resistance and better long-term shape stability. Silicone surfaces are easier to sanitize and less prone to oil seepage. The tradeoff is higher cost and a slightly firmer tactile feel compared to soft TPE blends.
Material quality varies widely within each category. Two silicone dolls can perform very differently depending on formulation and casting method. The same is true for TPE density and blend ratios. Buyers should therefore look for density description, tear testing claims, and long-term user feedback — not just the base material label.
Some manufacturers now use dual-density casting, reinforcing high-stress zones while keeping surface layers soft. This hybrid engineering approach often improves durability without sacrificing realism.
Material choice should be based on maintenance tolerance, usage frequency, and lifespan expectations — not just initial feel.
