Give a chestnut
Due to the material reasons, silicone dolls have the disadvantages of hard feel, poor tension and easy cracking when posing. If the Y-junction is relatively small, it is inconvenient to use and easy to crack, and the silica gel can't be repaired. Its advantages are no smell and no easy deformation. If the silicone doll is very ornamental, it is not so ideal and can't be repaired.
Compared with the doll made of TPE, it will smell a little fishy, and it will be a little oily because of the problem of making raw materials. If they don't, it means they are broken. The advantages of TPE material are softness, elasticity and strong tensile force. Posture is not easy to crack, and small cracks can be repaired (except violence).
Although TPE has many shortcomings, it does not mean that all materials are not good. For example, the medical-grade TPE imported from Japan is non-toxic and tasteless, which can also make the touch closer to the real skin, but its raw materials will be more expensive.
The above is a brief description of the two materials. The combination of silica gel head and +tpe mentioned above is to avoid the shortcomings of the two materials and combine the advantages of the two materials to present the most cost-effective combination.
So the bionic dolls on the market are not all made of silicone, but have different combinations.
