Glass, ceramics and vacuum.
Wood , rubber , glass
The Materials are of three kinds:- Conductors- Semiconductors and- InsulatorsThe Insulators have the property to stop the flow of electricity, because they have less number of free electronics, which can conduct Electricity.
Here are some examples for you; I hope they work!plasticrubberglassleadwoodclaypolyethylenediamondsoxygensulfurphosphorusI hope this helps!

Rubber, glass, and plastic are three common materials that can act as insulators by preventing the flow of electricity or heat. They have high resistivity which limits the transfer of energy through them.
Plastic wood and rubber are good insulaters. Electricity and heat do not transfer through them very well. If cars didnt have rubber tires they would be hit by lightning because there is no insulater. The metal on the car is a conductor though.
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.
A good insulator material is rubber and can block heat and electricity from almost anything. Glass is a good insulator too if you are trying to insulate electricity. Plastic is good as well. Most metals are OK conductors. Copper is very good, and Gold is the best, but it is heavy and expensive.
Electricity is the flow of electrons through a conductor. The three main substances that make up electricity in a typical circuit are conductors (such as metal wires), insulators (which restrict the flow of electrons), and a power source (such as a battery or generator) that provides the energy to move the electrons.
Three good insulators of heat are, maybe plastic, wood and glass! That's all I can think of right now but plastic and wood are very good insulators (etc. used of saucepan handles)
The three materials that I think is wood, plastic and glass.
Electricity is the flow of charged particles (often electrons), hence it flows easily where there are many 'spare' electrons (as in transition metals). An electrical insulator is something that does not have very many of these, for example the group 8 elements have a full outer shell, no electrons are 'free' as this process requires. Plastic insulates electricity.
