Many human being may no wonder about it, however rubber is, theoretically, a pretty fascinating substance. From its inception, that was an ext of a novelty than a useful form of latex. However, v time, notable inventors like Charles Goodyear and Michael Faraday made significant improvements in the moulding and activation of natural rubber, ultimately leading to the breakthrough of our favorite polymers in electronics today.

You are watching: Is rubber a good conductor of electricity

When us talk around the properties of rubber, among the most usual questions is whether rubber conducts electricity or not. Most people have an idea that steels conduct electricity while insulators such together plastic and also wood carry out not. The reality is much more than meets the eye.

So, walk rubber command electricity? No, rubber does not conduct electricity. Its prolonged chain-like polymer structure prevents the electron from moving freely. This is due to the strong bonding of electron in its valence shell that borders the carry of electrical current.

In rarely cases, the conductivity that rubber depends on the sustaining material(carbon or metallic substances). If the contains complimentary electrons, it might make rubber slightly conductive. Even so, these reactions need assistance, high temperature, and also voltage for charged ions/electrons come oscillate freely.

Further, permit us talk about Rubber and also its key feature: electrical Insulation.

What is Rubber?

Rubber, also known as cis-polyisoprene, is a polymer developed through the polymerization of cis-1, 4-polyisoprene. It is entirely made that carbon and also hydrogen atom (C 5 H 8).

Origin: It’s found most typically in latex, but also the sap native trees and other plants also as specific kinds the seaweed.

Uses: the is likewise mixed with different substances to create different types of rubber such together Nitrile, EPDM, Butyl, etc.

Its elasticity makes it valuable for a selection of products, specifically those provided for sporting goods, bumpers, and also tires. It is highly resistant come tear or rupture end time.

Types the Rubber

Types: following are the two broad species of rubber:

1. Natural rubber (or India rubber): that is well-known as latex, a milky white juice that oozes from cut in trees. This process is referred to as “tapping”. That contains small amounts (5%) the proteins, resins, not natural salts, and also even fatty acids.

Its structure renders it similar to silicone and gutta-percha. It is synthesized through conjugated diene((2-methyl-1,3-butadiene), also known as monomer isoprene. The dual bonds in it room in z configuration, boosting its elasticity.


2. Synthetic rubber (Neoprene): the is an artificial elastomer for which crude oil oil and petrochemicals serve as the raw material. That is developed with a mix of the adhering to conjugated dienes:

Isoprene (2-methyl-1,3-butadiene)1,3-butadiene,Chloroprene (2-chloro-1,3-butadiene)


Additional nature of Rubber

Hard structure because of chemical ingredient (van der Waals forces)High tensile strengthHigh abrasion resistanceThe resistivity of tough rubber at 20 degrees C amounts up come (1-100) x 10¹³ ohm m and also conductivity remains zero.

Why does not Rubber conduct electricity?


To understand this, let’s analysis the molecule structure and composition that rubber:

Chemical Formula :

2-methyl-1,3-butadiene, < CH-2=(CH-3)CH-CH=CH-2 >

1. Rubber is a hydrocarbon comprising hydrogen and dual bonds of carbon. The ratio of carbon come hydrogen atoms constantly exists as 5:8.

2. In addition, that non-metallic structure is organized with covalent bonds having primary devices of polymers(monomers). This units space entangled in a lengthy chain formation.

3. That atomic form is deprived of cost-free electrons (conduction bands or charge carriers) in the external shell. Therefore, there room no electron to run from one atom to another for a smooth circulation of electrical current.

4. On a similar note, follow to band theory, rubber has actually only sigma bond (strong covalent bonds) in addition to breakable pi bonds (non-overlapping) in the low energy valence band. Thus, leading to an empty higher energy tape (zero complimentary electrons).

5. These pi binding exist at positions like 2,6,10 and also are not conversely creating a huge energy gap between the 2 bands. Together a result, all the bonding electron of the valence band stay positioned.

And when specific electrical voltage come is passed with the end of the rubber, the electrons in the valence resist their activity to the conduction band, conducting nil electricity.

Moreover, it acts as an insulator until it’s heated past its electrical malfunction temperature. Until then, both species of rubber room bona fide electrical insulators.

Exception: despite many products made indigenous rubber likewise contain other products that can make them conduct electricity. Because that example, most rubbers supplied in shoes – and sometimes gloves and also wetsuits – are mixed with carbon black, which conducts power when blended with rubber.

This provides the rubber contempt conductive under unsure circumstances.

What is the difference between a conductor and also an insulator?

Conductor: the is things that quickly transfers heat, electricity, or sound from one atom to another. The molecules within it have actually an uneven circulation of electrons that readily passes one electric existing and enables a large amount of fee to flow through it.

Example: Copper wire, Graphite, human being body (prone to electrical shock), salt (aqueous solutions)

Insulator: that is defined as a substance the does no pass an electric present easily, and enables only a negligible amount of charge to circulation through that under excessive voltages. Otherwise, that opposes and also stores it.

Example: Glass, Rubber, Plastic, Wood, etc.

The terms conductor and also insulator are based upon the capacity of a material to allow the movement of electric charge. The steels that us are used to managing in most circuitry are instances of conductors.

Insulators are typically used in place of a steel where corrosion is a hazard due to the fact that their literal function is to prevent the flow of electricity.

How have the right to you phone call if a substance conducts electricity or not?


Conducting power essentially way a material have the right to let electrical energy pass with it. It’s vital to know that not all materials have this ability. Periodically this relies on the kind of material and its components as well.

A conductor has actually mobile electrons and atoms, a semiconductor has actually ions or feet of electrons and an insulator is devoid of mobile charges.

To be specific, listed below are the three elements that identify conductivity and also are dependency on the material’s nature.

1. Complimentary Ions: The compounds with solid conductivity break right into charged atom or ions in water. They space bound along with attractive electrostatic forces and also let the existing flow smoothly.

They are likewise deficient in carbon atoms. They space inorganic. Top top the contrary, insulators space inorganic and weak electrolytes in nature and contain carbon atoms.

2. Temperature: sudden temperature rise, boosts the kinetic energy of ions in conductors compelling castle to relocate hastily.

But, in the instance of rubber, temperature elevation will not affect. However, it might deteriorate itself and also get discolored because of its polymer structure. The warmth affects the prolonged chains causing vibration and also shrinkage.

3. Density: Low-density building material have greater electrical conductivity. For instance alkali metals. Lock contain one complimentary electron in their external shells carrying existing throughout their surface.


Rubber is a product the latex with its distinctive properties that room used across different production industries. It likewise works as an insulator because it doesn’t save any cost-free electrons to command electricity. Its internal structure provides individual electrons secure eliminating all avenues for them to move easily carrying an electrical current.

It is a product made from the polymerization of number of compounds joined together in chains. Rubber is existing in almost everything we do. Rubber from her car’s tires is the reason you, and also other drivers on the road, space safe when driving in poor weather and other conditions.

Many civilization use it come seal windows, cars, and buildings native the weather. They also use it for boots, gloves, defense pads, balloons, mattresses, operation gloves, and bandages together it gives comfort and protection from electric shocks.
