insulators...
Objects that conduct electricity poorly are called poor conductors of electricity or insulators . There is a difference though. Poor conductors of electricity are capable of conduction under certain circumstances while insulators cannot conduct electricity under any condition, example ; air is a poor conductor of electricity as it cannot conduct under normal conditions but lightning is able to pass through it during a storm.
No material exists that doesn't conduct electrical charges at all. We call materials that conduct electrical charges poorly insulators; a material that didn't conduct electricity at all would be a perfect insulator.
Ammonia is a gas. Gases do conduct electricity, as all materials do. However, they conduct electricity so poorly that we consider them insulators. "Electricity" requires the movement of electrons. In a gas, these electrons are too dispersed to provided any measurable current.
well i only know one really good one, i am only in 6th grade, but rubber is a really good one
an insulator
An insulator. (i.e. glass)
The general term for "materials that conduct heat poorly" is "insulators". Examples would be wood, many ceramics, and cloth such as wool or cotton.
Only extremely poorly.

In a gas, these electrons are too dispersed to provided any measurable current. So it does conduct electricity and heat, however conducts them both very poorly ;')
No. Most metals can conduct energy well (energy implying includes electricity and heat). However, some, such as nichrome (an alloy of nickel and chromium) conduct electricity very poorly. Nichrome has a high resistance and therefore, when electricity is chanelled through nichrome wire, resistance in the wire causes it to heat up.
In general a material is both a good conductor of electricity and heat if it has lots of free conduction band electrons, effectively forming an "electron gas". Metals are in this category. Ionic conductors usually conduct electricity well but heat poorly. Many circulating fluids conduct electricity poorly but heat well.
So that they can get poorly-payed labourers to sort it and then they sell the recycled materials on for a profit.
