Insulating materials are composed of atoms with <u>tightly bound outer electrons.</u>
<h3>What is Insulating Material ? </h3>
The material that stop the flow of Sound, Heat and Electricity by them are called Insulating Material. Insulator are the materials whose atoms have tightly bound outer electrons because electrons are not free to shared by neighboring atoms.
Examples: Glass, Plastic, Rubber, Air and Wood.
<h3>What are the types of Insulating Material ?</h3>
There are mainly three types of Insulating Material:
- Heat Insulator
- Electricity Insulator
- Sound Insulator
Thus from the above conclusion we can say that Insulating materials are composed of atoms with <u>tightly bound outer electrons.</u>
