The lifespan study of the platinum silicone of the granny sex doll revealed that in an accelerated aging experiment (70°C/85% humidity environment), the medical-grade silicone retained 91% of its tensile strength after 10,000 hours of testing, and its elongation at break was >750%, far exceeding the 67% and 480% of ordinary torso sex dolls. The breakthrough in anti-yellowing technology lies in the nano-titanium dioxide coating - after 2000 hours of ultraviolet irradiation, the color difference ΔE <1.5NSB is almost indistinguishable to the naked eye. Users need to follow a special maintenance guide: apply silicone regeneration agent (containing polydimethylsiloxane) every month, and avoid using detergents containing isopropyl alcohol that may cause molecular chain breaks. The service life of a properly maintained high-end product can be extended to more than 8 years.
