Silicone and TPE are the predominant materials for realistic sex dolls, each offering distinct characteristics. Understanding their differences is crucial for informed selection.
Silicone Dolls
Pros:

- Superior Realism & Detail: Holds intricate details like skin texture and facial features exceptionally well.
- Excellent Durability: Highly resistant to tearing and puncturing compared to TPE.
- Non-Porous Surface: Less prone to harboring bacteria and easier to clean effectively with proper methods.
- Stable Material: More resistant to oils, sweat, and temperature changes; retains shape well.
- Wide Range of Skin Tones: Can achieve very realistic and varied coloring.
Cons:
- Higher Cost: Significantly more expensive than comparable TPE dolls.
- Firmer Feel: Generally feels less soft and yielding than TPE, though high-grade silicone improves this.
- Potential Joint Stiffness: Skeletons can sometimes feel stiffer, affecting posing.
- Repair Difficulty: Damages are harder to repair seamlessly than with TPE.
TPE Dolls (Thermoplastic Elastomer)
Pros:
- Softer, More Yielding Feel: Closer to human skin softness and flexibility in many grades.
- Lower Price Point: More affordable than silicone, offering a cost-effective entry.
- Self-Healing Minor Scratches: Minor surface marks can sometimes blend back due to material elasticity.
- Generally Easier Posing: Material flexibility often allows for smoother joint movement.
Cons:
- Porous Material: Absorbs oils and fluids readily, demanding stricter, more frequent cleaning and thorough drying to prevent microbial growth.
- Shorter Lifespan: More susceptible to tearing, staining (especially from dark fabrics), and material degradation over time, even with excellent care.
- Requires Powdering: Needs regular application of cornstarch/talc to maintain surface finish and reduce stickiness.
- Less Detail Fidelity: Intricate facial features and skin textures may appear slightly softer or less defined than silicone.
- Odor Potential: May have a slight, persistent plastic smell; higher-quality TPE minimizes this.
- Oil Leaching: Can release small amounts of mineral oil over time, requiring protection for fabrics/furniture.
Key Facts
- Material Choice is Primary: Silicone vs. TPE is the fundamental decision impacting cost, feel, durability, and care requirements.
- Hygiene is Paramount: Both materials require diligent cleaning and drying after every use. TPE demands extra vigilance due to porosity. Use only compatible cleaners (mild soap/water, specific toy cleaners).
- Long-Term Maintenance: Silicone needs less frequent but more skilled repair. TPE needs constant preventive care (powdering, meticulous drying, stain avoidance) to slow degradation.
- Temperature Sensitivity: Avoid extreme heat/cold and direct sunlight with both materials to prevent damage.
- Weight Considerations: Full-size dolls of either material are very heavy (often 70-120+ lbs / 30-55+ kg); consider mobility/storage needs.
- Sterilization Limitations: Complete sterilization is impossible; diligent hygiene is essential for safety.
Conclusion: Choose silicone for maximum realism, durability, and ease of cleaning (though at a premium cost). Choose TPE for superior softness and affordability, but be prepared for intensive maintenance and a potentially shorter usable lifespan. Prioritize rigorous hygiene regardless of material.
