If you just had a piece of silicone sitting there on a table, it would for sure last. When you have silicone wrapped over a plastic or metal endoskeleton that can move freely underneath . . . that’s a different story.
Try Mezco for example. For their 1/12 Batman figure they decided to use a squishy, silicone body suit over a metal armature. Well it IS durable but if you leave the body in articulated poses or even with the arms down, it rips the suit apart. To keep in good condition, you have to keep it posed in it’s original mold injection stance,

They (JND) are taking a plastic and metal skeleton and wrapping silicone components over it. If you pose it in anything but it’s originally injection mold, it’s going to stress in places. Likewise, if the head, neck, or finger joints break, there is no way to access it without ripping the silicone skin off.
You say this like it's for certain ... which it is for the items you mentioned.
JND use the highest graded medical silicone, and if I recall, they have experimented in its mixology. Kojun has been practicing this technology for many years so I'm sure the research in the silicone they use and its ability to upkeep its properties without degredation has been pushed over those years.
I'm without doubt that absolute idiots will be some of those to buy this and constantly be moving these pieces beyond what would be normal, no less with greasy hands that will damage, but I'm also certain that if handled with care they will uphold themselves.
The medical silicone for their 1/3 has been told to JND by the manufacturer of a guarantee of quality without defect for a 'lifetime' equated to 30+ years.
