There are many materials that are used to insulate.
If the idea is to keep sound energy from entering a building steel springs, or rubber blocks, can be placed between a mechanical device and the building structure, or a fiber type insulation can be placed inside an air duct to keep the sound of the air in motion from being transferred to the building. Cloth sections are placed between metal duct work and a large centrifugal fan to stop sound transfer and/or vibrations from being transferred to the duct.
Porcelain or specially formulated epoxies are used to insulate high voltages from the ground. Special plastic or rubber-like material is used to insulate electrical wires.
Fiberglass bats, closed cell foam, cork, or even ground up paper are used for thermal insulation.
Almost any solid material, flexible or rigid, can be used to insulate from light.

∙ 13y agoInsulators used for high-voltage power transmission are made from glass, porcelain, or composite polymer materials. Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. Porcelain has a dielectric strength of about 4--10 kV/mm. Glass has a higher dielectric strength, but it attracts condensation and the thick irregular shapes needed for insulators are difficult to cast without internal strains. Some insulator manufacturers stopped making glass insulators in the late 1960s, switching to ceramic materials. Recently, some electric utilities have begun converting to polymer composite materials for some types of insulators. These are typically composed of a central rod made of fibre reinforced plastic and an outer weather shed made of silicone rubber or EPDM. Composite insulators are less costly, lighter in weight, and have excellent hydrophobic capability. This combination makes them ideal for service in polluted areas. However, these materials do not yet have the long-term proven service life of glass and porcelain.

Are ferro magnetic materials insulators?
Well, iron and its alloys are ferromagnetic and they are conductors.
How are the insulators alike?
Nothing in particular. Most of the objects in our world are insulators, in fact if something is not metallic, odds are it is an insulator.
What do you call poor conductors?
Insulators.
What will not carry electricity?
insulators. All the insulators. Like fabrics
What are three kinds of matter that conducts heat poorly?
Things that are nonmetal conduct heat poorly. These insulators would include plastic, rubber, Styrofoam and wood. This is due to the characteristics of the materials.
Which materials insulators?
the materials are rubber and plastic
What is the definition insulators?
Insulators are materials that prevent electrical flow.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What are not insulators?
Insulators are materials that don't conduct heat well, or (for electricity), materials that don't let electricity pass through them. In general they are non-metallic materials.
Why such materials are good insulators?
Dielectric meterials are good insulator materials
Which materials make the best insulators?
minecraft
Name 2 insulators?
Insulators are materials or substances that do not readily allow the passage of sound or heat. Two examples of insulators are glass and porcelain.
What is the name for materials that do not allow heat to pass?
Materials that do not allow heat to pass are insulators. (In real life, there are no perfect insulators, but if not much heat passes, then it is an insulator.)
What are materials that are poor conductors of electricity called?
They are insulators.
Materials that are poor conductors are what?
normally called insulators
What Types of building materials are conductors and insulators?
electrical
How are superconductors different from insulators?
Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
