In insulators the bond energy between atoms in the material they form is very high. We need to give large energy to overcome that bond energy and set free the electrons.
As electrons are not freely available It doesnt conduct well.
There's a kind of circularity in the question. Anything that doesn't conduct electricity for any reason is called an insulator. So any substance where the electrons are too tightly bound to atoms and cannot migrate is called an insulator. Anything that manages to let electrons migrate wouldn't be called an insulator.
