Some objects that can exhibit both conductor and insulator properties are semiconductors like silicon and germanium. These materials can conduct electricity under certain conditions, such as when doped with impurities, but can also act as insulators when pure. Additionally, some metals like aluminum and copper can have insulating properties when coated with a non-conductive material, such as enamel in wires.
If you can think of any objects that are made of glass, rubber, or plastic they are all insulators. (think of food containers things you drink out of -most of them are conductors) Most things made of metal are conductors. (metal things you eat with, metal furniture objects, anything copper)
Assuming you mean an electrical conductor, No. To be a conductor, a material must have free electrons in the conduction band of the atoms. Metals have free electrons intrinsically in these bands, and so make great conductors. If you mean heat conductors, the answer is also no. Some objects are insulators of heat.
Insulators are like rubber and wood because insulators that stops the flow of electrical charge. Conducts are the opposite so the items would be metal .
Conductors conduct heat and electricity well because they have delocalised electrons in their structure. Insulators, on the other hand, do not have delocalised electrons and therefore do not conduct heat and electricity as a conductor, although they do conduct to some extent.
Most substances fall into two categories - conductors and insulators. Conductors are those which electricity can pass through relatively easily. Metals are the usual example, but other substances such as graphite and polar liquids such as water are also good conductors. Insulators are poor conductors: those that electricity cannot pass through easily. Most plastics are insulators. Some substances fall in between: these are semiconductors, which allow electricity through in some instances, but not in others. This property makes them very useful in electronics. Some substances can be such good conductors that, under some circumstances, they can allow electricity to pass through them with no resistance at all. These are called superconductors.

Keys are usually made from some metal or alloy. If they are, they are good conductors, both of heat and of electricity.

Conductors are materials that allow electrons to flow easily through it. Metals are the best examples of conductors. Insulators to the opposite; they don't like letting their electrons flow. Glass, rubber, and wood are some examples of insulators.

Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
Conductors conduct heat and electricity well because they have delocalised electrons in their structure. Insulators, on the other hand, do not have delocalised electrons and therefore do not conduct heat and electricity as a conductor, although they do conduct to some extent.

Some are, such as silicon and germanium. Others are non-conductors known as insulators, such as glass.
Regular car tires are insulators. Some aircraft tires are conductors.
Some examples of heat conductors are nickel, coalbolt, iron, steel Some examples of heat insulators are rubbber,glass,wood
