Insulation is directly proportional to resistance. More resistance means more insulation. And if a material is denser (i.e. the particles are situated closer to each other), then the resistance is more.
Hence, more density-->more resistance-->better insulation
And since different materials have different density, hence they also have different insulations.
hope it helps.. :)

What are some items that insulators are found in?
Insulators are commonly found in a variety of items, including electrical appliances, power lines, and circuit boards. They are used in materials like rubber, glass, and ceramic to prevent the flow of electricity and protect users from electric shock. Additionally, insulators can be found in thermal applications, such as in building materials and thermal clothing, to reduce heat transfer.
List of good insulators?
Some materials such as "silicon dioxide or teflon" are very good electrical insulators. A much larger class of materials, for example "rubber-like polymers and most plastics" are still "good enough" to insulate electrical wiring and cables even though they may have lower bulk resistivity. These materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts)."
What are some nonexamples of insulater?
Nonexamples of insulators include materials that readily conduct electricity or heat, such as metals like copper and aluminum. Other examples are water, graphite, and certain types of ceramics that allow for the flow of electric current or heat transfer. These materials contrast with insulators like rubber, glass, and wood, which resist the flow of electricity and heat.
What are the characteristics of materials to be used for specific project?
The characteristics of materials to be used for a specific project depend on the needs of the project. There are several different types of materials that work better for some products then others. The first step would be to determine which materials would work best.
Are apples insulators?
No, apples are not considered to be insulators. Insulators are materials that resist the flow of electrical current, while apples are organic materials with some moisture content and do not have insulating properties.
Why are some materials good insulators while others are not?
Materials that are good insulators have a high resistance to the flow of heat or electricity due to their molecular structure. This can include materials with tightly packed molecules or those that contain trapped air pockets, such as rubber or fiberglass. In contrast, materials that are poor insulators have more free-flowing electrons or a looser molecular structure, allowing heat or electricity to pass through more easily.
What causes some materials to be good insulators of electrcity?

What are some heat insulators?
Some heat insulators are fiberglass, polyurethane foam, and polystyrene. Two other thermal insulators used as insulating materials in building construction are mineral wool and cellular glass.
Why some of the materials are insulators?
Materials are insulators because they have tightly bound electrons that do not move freely. This restricts the flow of electricity through the material. Examples of insulators include rubber, plastic, and glass.
5 common materials insulators?
Some common materials used as insulators include rubber, plastic, glass, ceramic, and air. These materials have high electrical resistance and are used to prevent the flow of electricity, heat, or sound. Insulators are essential components in electrical and thermal insulation processes.
What matirials are good insulators except foam?
Some other materials that are good insulators are wood, rubber, glass, and fiberglass. These materials have low thermal conductivity, preventing the transfer of heat.
Why do you think some materials are better conductors of heat than others?
Materials conduct heat differently based on their atomic structure and the ability of their particles to transfer energy through vibrations or collisions. Materials with closely packed particles and strong intermolecular forces, like metals, are better conductors of heat as they allow for fast energy transfer. Other materials, like gases and insulators, have looser arrangements and weaker bonds, resulting in poorer heat conduction.

Which is true heat can travel well through all materials or heat can travel well through some materials?
Some, but not all. Some materials are insulators- heat does not travel well through them.
What can not carry electric current easily?
Materials that do not conduct electricity easily are known as insulators. Some common examples include rubber, glass, and plastic. These materials have a high resistance to the flow of electrical current due to the lack of free electrons.
What carries electric current not easily?
Electrical insulators. Materials such as rubber, plastic, wood, air and some ceramics are all poor conductors of electricity, or good insulators.
