Yes. Rubber is electrically nonconductive.
If you mean "dis"allow the flow, it's because electrons cannot travel easily between the atoms of the material.
gold silver and copper can not be conducted.
Conductive substances allow the flow of electricity due to their ability to carry an electric current, whereas nonconductive substances do not allow the flow of electricity. Conductive substances typically have free-moving electrons, while nonconductive substances have tightly bound electrons that do not facilitate the movement of electric charges.
any material that will not allow electricity to pass through it. rubber, plastic, some electrically conductive materials are metals, esp. gold, water, neon gases insulators, glass, paper :)
Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution has no effect. Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary conductivity caused by condensation is to be expected. Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments). Pollution Degree 4: The pollution generates persistent conductivity caused by conductive dust, rain, or snow.
If conductivity were the only issue, silver would be the best but it is expensive.Considering both cost and conductivity both copper and aluminum are good choices, but aluminum cannot be soldered and its oxide is hard and nonconductive causing interconnection resistance to rise over time and has caused house fires.

Silicon tetrachloride is a nonconductive compound in its pure form. It does not conduct electricity because it does not contain free-moving electrons that are necessary for conducting electricity.
A basic capacitor is made up of two conductors separated by an insulator, or dielectric. The dielectric can be made of paper, plastic, mica, ceramic, glass, a vacuum or nearly any other nonconductive material. Some capacitors are called electrolytics, meaning that their dielectric is made up of a thin layer of oxide formed on a aluminum or tantalum foil conductor.
When a material is identified as conductive it means that an electrical current can pass through that material. Some materials do not readily conduct electricity through the material, but will dissippate static electricity so that there is not a build up of charge on the material. Humidity and applied voltage can make a big difference on how effective the less conductive or the dissipative materials respond. Some other details about how fast a charge is released and so forth are also considerations when determining a materials response to electrical energy. In short, a conductive rubber has a Ohm resistance no larger that about 1,000,000 Ohms (often referred to as Ohms/square). Dissipative rubber has a resistance of about 1,000,000 to 1,000,000,000 Ohms. "Anti-Static" rubber is about 1,000,000,000 to 1,000,000,000,000 Ohms. Anything over this is considered insulative rubber. (refer to Boedeker.com for more detailed information).
Use a nonconductive item, such as wood. Anything nonmetal or conductive will not allow heat to pass through. For example, if you are in the car after a long day at the pool or beach, you may notice that the car is hot, because it is made of a conductive material. If it was made of wood, you would not feel the heat.Get rid of the heat. If there is no heat, there is nothing to transfer. You can make it cold, you can trap it with no oxygen so it can't spread, just make the heat go away.
