“Silicone” is really a class of chemicals, not one particular thing. It’s made of a single molecule (called a monomer) that’s joined in chains. A bunch of relatively short chains together make a slippery oil because they slide past each other easily.
Combine a bunch of long chains and link them together and you get a whole network, which gives you a solid substance with different properties. Since the chains are linked into a net, they can no longer slide past each other.
Silicone itself isn’t usually sticky, it becomes so when it absorbs some other types of oils for reasons i don’t understand well enough to explain
