Introduction
The adult toy industry has seen remarkable advancements in materials technology over the past two decades, with Thermoplastic Elastomer (TPE) and medical-grade silicone emerging as the two dominant materials for high-end sex dolls. This in-depth comparison will examine every aspect of these materials to help consumers make informed decisions when investing in a premium sex doll.
Material Composition and Manufacturing
Thermoplastic Elastomer (TPE)
TPE is a hybrid material combining the properties of rubber with the processing advantages of plastics. The typical TPE blend used for sex dolls contains:
Styrene-based block copolymers (for elasticity)
Polyolefin blends (for structural integrity)
Mineral oil (up to 30% by weight for softness)
Various stabilizers and pigments
Manufacturing process:
Granules are melted at 180-220°C
Injected into molds under high pressure
Cooled to room temperature
