Actually, plastic is not a bad conductor of heat and electricity, it's an insulator.

An insulator is a substance that resists the flow of heat or electricity through it and plastic

resists both of these.

cos it made up of different man made materials and the heat can usually clearly see right through it.

im just guessing, but i think it's the stuff it's made of. it is flammable be careful plus it depends what kind you are talking about

it's considered an insulator, which is the opposite of a conductor (which are usually metals). it has to do with it's atomic structure..etc and it's high amount of resistance.

rubber is one of the worst conductors

copper is one of the best conducters

All types of plastics are nonconductors of electricity because plastics are polymers of organic molecules and have no free electrons for conductance.

Is plastic or Styrofoam the poorest conductor of heat?

The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.


Some Examples of poor thermal conductor?

foam plastic rubber


How is plastic foam is a poor conductor of thermal energy?

they have a very large amount of air present in them, plastic is a bad conductor


How is a foam coffee cup a good insulator?

The foam contains air, which is a poor conductor of heat.


Is a plastic pipe an insulator?

Yes , plastic is a poor conductor of heat!!:) Metal is a good conductor though


Why do you use a foam cup instead of a beaker in an experiment?

foam cup is a poor conductor of heat! haha;] msg me!!


Why materials such as plastic foam feather and fur are poor conductors of thermal energy?

Because they trap air, which is a poor conductor of heat. They hold surfaces away from each other, to stop direct conduction.


How does plastic foam reduc heat loss?

Plastic foam consists of bubbles containing air or gas. Those bubbles are poor conductors of heat, and reduce the transfer of heat from warmer to cooler areas.


Is the material mica a poor conductor of heat?

mica is a plastice, so it is a poor conductor of heat and electricity. Mica is a mineral, not a plastic. But you're correct about its insulating properties.


A substance that is a poor conductor is called?

A substance that is a poor conductor. Is anything that is not metal. Such things as an insulator that includes wood, plastic, polystyrene foam, fabric, gas


Is foam a good conducter of heat?

In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity


How does a plastic box help to reduce heat loss?

Plastic is an insulator therefore it is a poor conductor of heat. A plastic box will therefore be able to keep a lot of heat on the inside.
