Here is a brief description describing some of the usual differences between silicone sex dolls and TPE sex dolls, although this may not apply to a small number of specially made pieces.
1. Silicone sex dolls are in general more realistic and beautiful in appearance. They are harder, making them less likely to tear, have a longer lifespan, and easier to apply make-up to. TPE is softer, it is easier to tear and has a shorter lifespan.
2. TPE offers the better overall sexual experience as it is more flexible and softer. Silicone, in contrast, has lesser elasticity and can be , for some, a bit too hard for the optimal experience.
3. A silicone doll has a longer lifespan, while a TPE doll is more affordable in price.
4. Silicone is slightly lighter than TPE and has a slightly lower oil yield.
(Note: Due to technological advancements both type of materials have improved significantly. Many TPE products can now be crafted in more beautiful detail and better make-up. They are more tear resistance. Also, silicone products are now much softer than previously, substantially improving the overall sexual experience)
