The principle of silicone self-lubricating is mainly related to its surface energy.
Surface energy refers to the measurement of the degree of interaction between an individual's surface and external substances. It is an important concept to help understand and explain surface phenomena such as liquid viscosity, contact angle, surface tension, and wettability.

There are many silicon-based functional groups on the surface of silicone gel, which easily interact with water molecules in the air. When the surface of silicone is rubbed or squeezed by external substances, the silicon-based functional groups on the surface of silicone quickly attract surrounding water molecules, forming a small lubricating film, thereby reducing the contact area between the silicone surface and the friction object, lowering the surface energy between the silicone and the friction object, and reducing the friction coefficient.
