Yes. You can test it by sticking a piece of graphite, found in mechanical pencil, in boiling water for a minute and the temperature will stay the same. It keeps the thermal energy out and doesn't let it pass through. So, graphite is a good insulator.

∙ 13y agoGraphite is NOT an insulator:
- Unlike diamond (another carbon allotrope), graphite is an electrical conductor, a semimetal, and can be used, for instance, in the electrodes of an arc lamp.
- Graphite can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity, flat honycomb-like hexagonal atomic carbon layers).
These valence electrons are free to move, so are able to conduct electricity. However, the electricity is only conducted within the plane of the layers.

Diamond is an insulator while graphite conducts electricity?
Diamond is considered the hardest mineral known to man, while graphite is one of the softest. Diamond is an excellent electrical insulator, while graphite is a good conductor of electricity. This is due to the way the carbon atoms are arranged in each mineral.
Does carbon have good conductivity?
yes because that is why batteries contain carbon
Which non metal forms the lead' in a pencil?
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Which forms of carbon are insulators?
Carbon may be an insulator or it may be a conductor. It depends on which allotrope of carbon we are investigating. Graphite is a conductor, but diamond is an insulator. In either case, the manner in which electrons are bound in the structure determines whether any of them are free to contribute to current flow. In graphite, we find electrons in the conduction band, and it will conduct electric current. In diamond, the electrons are not in the conduction band, and are not available to support current flow.
What are some uses of carbon graphite?
carbon and graphite are one in the same, graphite is a form of carbon a use for graphite is the lead in your pencil (it's not actually lead, it's graphite) and it is also a good lubricant ;)
Is a pencil a insulator or conductor?
Wood is a fair insulator, but graphite is a reasonably good conductor, so it depends on which part of the pencil you're measuring.
Is a pencil an insulator?
The shell or carapce made of wood in pencil having a graphite refill in it is an insulator but as graphite is good conductor of electricity so overall a pencil can cunduct current in it.
Is graphite a heat conductor or insulator?
insulator
Is a non metal a good heat insulator?
yes with exceptions like graphite
Is graphite an insulator or conductor of electricity?
Graphite conducts electricity.
Is graphite a conductor or an insulator of electricity?
Graphite conducts electricity.
Is a lead of a pencil conductor or insulator.?
No. Lead is a realtively good conductor. The insulator is the wood on the outside of the lead.
Diamond is an insulator while graphite conducts electricity?
Diamond is considered the hardest mineral known to man, while graphite is one of the softest. Diamond is an excellent electrical insulator, while graphite is a good conductor of electricity. This is due to the way the carbon atoms are arranged in each mineral.
Which non metallic solid is not an electrical insulator?
graphite
Is graphite a conductor or insulator?
Graphite is a conductor of electricity, but its conductivity varies greatly with direction: Conduction is high along the plane of the sheets of carbon atoms found in a single crystal of graphite, but much lower perpendicular to this plane.
Which would be the best insulator carbon or silicon or aluminum or oxygen?
Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
Is a carbon rod a conductor or insulator?
As regards electrical conduction, if the carbon rod is graphite, it's a conductor. If the carbon rod is diamond, it's an insulator. We have to specify the allotrope of carbon used to make the rod to discover whether it's an insulator or conductor.
