Silicone is a medical-grade synthetic material known for its heat resistance, non-toxicity, and texture similar to human skin. It is often used in the medical and cosmetic fields, giving it a high-end and safe image.
TPE (thermoplastic elastomer), on the other hand, is a blend of plastic and rubber. Softer and more elastic than silicone, it offers a good compromise between flexibility and softness . It is also less expensive, which makes it popular in entry-level or mid-range sex dolls. Beyond simple chemical composition, the difference between silicone and TPE also lies in their design philosophy. Crystallized silicone, for example, undergoes an advanced polymerization process, allowing for a more consistent and resistant structure. This homogeneity guarantees not only superior durability, but also perfect reproducibility down to the smallest anatomical details. Conversely, TPE can vary between batches and manufacturers, resulting in differences in texture, odor, or even durability over time.

When it comes to tactile realism , silicone wins hands down. Its dense texture better replicates the natural tension of human skin. Softer TPE can feel bouncier but can sometimes be too supple or slightly sticky. When looking for an immersive experience, touch becomes central. Silicone recreates the typical resistance and bounce of a human muscle under the skin. TPE, more spongy, feels pleasant but less "lively." Whereas silicone can simulate muscle tension or softer areas like the hips, TPE offers a more uniform feel. The choice therefore depends on the type of realism sought: fine sensitivity and anatomical precision for silicone, overall softness for TPE.
The question of realism is not limited to the softness of the surface . The overall rendering of an intimate product also depends on its ability to reproduce the micro-deformations of the skin, its perceived temperature, or even its response to pressure. Silicone, especially when crystallized as with PTIKU, reacts with a progressive "rebound". We sometimes speak of shape memory: the material slowly returns to its place, reproducing the natural tensions of a living body.
TPE , being more elastic, gives an immediate "bouncy" effect, often perceived as more artificial. At room temperature, it can also become a little sticky, which detracts from the sensory experience. From an artistic point of view, silicone allows for more detail: skin texture, surface grain, transitions between soft and firm areas. It is these subtleties that create stunning realism. TPE, although very flexible, is more homogeneous, which reduces the illusion of life in high-end models.
Silicone is ultra-resistant , non-porous , and easy to maintain . It retains its original shape and color. TPE is porous, retains bacteria, and weakens more quickly without proper care. Demanding users will quickly notice the difference: a well-maintained silicone model can last for years without losing its beauty. It is resistant to temperature variations, ambient humidity, and even moderate exposure to sunlight. For its part, TPE, despite its softness, suffers from limitations: it expands more easily in heat, can crack if it dries poorly or if it is stored in poor conditions. TPE also requires storage precautions, because it sticks more easily to fabrics or plastic packaging if poorly protected.
| Criteria | PTIKU Hybrid Silicone | Unknown TPE |
|---|---|---|
| To touch | Very realistic, human skin | Less firm, sometimes too soft |
| Resistance | Excellent, does not deform | Fragile to tears |
| Interview | Easy, non-porous | Absorbs liquids, more delicate |
| Lifetime | Long (several years) | Shorter |
| Price | Higher | Cheaper |
TPE is much more accessible, with prices up to 50% lower . Silicone remains more expensive, but its durability justifies the long-term investment. It's not just about the purchase price, but also the cost of use. A €300 TPE doll that lasts 18 months can cost more over 10 years than a €700 silicone model that remains impeccable for more than a decade. In addition, some second-hand platforms reveal that silicone models are more easily resold and at a better price, proof of their perceived durability. While TPE remains a good entry point for beginners, silicone stands out as an investment. But it's a rational investment: less maintenance, longer lifespan, better resistance to wear and humidity. A well-preserved silicone sex doll retains its value and initial condition, which is rarely the case with TPE models after two years. The costs associated with silicone aren't just the material, but also the precision of the molding, which is often done by hand. This level of finish explains the higher price. However, the overall cost over 5 to 10 years is much more advantageous, especially when you consider maintenance, aesthetic stability, and lubricant resistance. In short: for a realistic, long-lasting, and hygienic experience, silicone fully justifies its price in 2025. For those looking for a more affordable alternative, our page dedicated to realistic inflatable dolls offers an innovative selection of practical and discreet models.
Silicone finishes allow for very precise rendering. TPE is more limited, but offers lower-cost options. Another often underestimated advantage of silicone is its aesthetic stability. It retains its colors, even the most delicate shades like subcutaneous pinks or blue veins , while TPE can see these details fade over time. For lovers of artistic realism, hyper-detailed finishes are only possible with silicone: textured skin, layered pigmentation, and translucent effects are all assets impossible to render with TPE . Silicone allows for the more discreet integration of mechanical systems as can be seen in the video of the VibraMotion motorized system , demonstration of fluidity and on-board ergonomics.
Silicone requires water-based lubricants. TPE tolerates more products but remains vulnerable to degradation. Some users make the mistake of neglecting this crucial aspect. Silicone is a chemically stable material, but it reacts with other silicones. Therefore, only water-based lubricants are recommended. An oil- or silicone-based gel could damage the surface, creating irreversible sticky areas. TPE, on the other hand, can absorb substances, which poses hygiene problems. This porosity is one of the main obstacles to safe, intensive use.
Silicone : regular, demanding users, looking for quality.
TPE : occasional use, first purchase, tight budget. A novice buyer, curious to test the experience, can very well start with a TPE model. He will benefit from a good pleasure/price ratio. But as soon as we are looking for a more realistic, regular experience without tedious maintenance, silicone is essential. It is not just a luxury choice, it is a choice of tranquility, security, and consistency over time. To discover our crystallized silicone creations, visit the Our PTIKU Creations collection .
Rigorous maintenance ensures the durability, hygiene, and sensory quality of your sex doll. Here are the simple steps to follow:
These simple steps will extend the lifespan of your sex toy, whether it's made of crystallized silicone or TPE. If you're also exploring intimate accessories, our ultimate guide to male sex toys offers a selection to suit every desire.
In 2025, crystallized silicone is the benchmark for a high-end experience. For a discovery or a limited budget, TPE remains a relevant option. PTIKU recommends custom-made silicone for its longevity and comfort. With rising expectations around the sensory experience, materials must evolve. Crystallized silicone now represents the pinnacle of comfort and precision. This material is to the sex doll what the OLED screen is to the television: a new benchmark. It also allows for the integration of innovations such as motors, sensors, or heating systems without loss of quality. For this reason, PTIKU has chosen to use only medical-grade silicone, tested, validated, and calibrated to provide a tactile rendering as close as possible to living skin.
