What is rubber in polymers?

Plastics and rubber materials are both made from the same families of polymers. The polymers are mixed with a complex blend of materials known as additives. Rubbers are elastomers, these are polymers with an elastic property. This elasticity differentiates rubbers from plastics.

Why rubber is a polymer?

Natural Rubber is a polymer of Isoprene meaning it is built of repeating isoprene units derived from conjugated diene monomers. It is from the monomer isoprene (2-methyl-1,3-butadiene). The double fonds formed in the polymer chain of natural rubber after polymerization have the Z configuration.

Does polymer have rubber?

Rubber is an example of an elastomer type polymer, where the polymer has the ability to return to its original shape after being stretched or deformed. The rubber polymer is coiled when in the resting state.

How is polymer rubber made?

Chemical agents are used to turn the individual polymers into polymer chains. This forms a rubber substance. In a process called vulcanisation, the rubber substance will be processed into a rubber product. Vulcanisation works by converting polymers into more durable material by adding accelerators such as sulphur.

What is rubber and its types?

Ans: Rubbers are of two types: Natural and synthetic. Natural rubber is extracted from the latex of the rubber plant, and synthetic rubbers are artificial elastomers that are synthesized from petroleum products. They have double tensile strength than natural rubber.

What is the difference between rubber and polymer?

Some polymers are synthetic whereas other polymers are naturally occurring compounds. Plastic is a synthetic polymer whereas rubber is found as a natural polymer. This is the main difference between plastic and rubber. Both these compounds are very useful in the production of different items.

Are polymers plastic or rubber?

Yes, polymer as a term that greatly denotes plastics, but nonetheless, this term also describes the characteristic of rubbers. Although rubber is more of the specific elastomer (a viscous or elastic variation of polymers), it is still considered to be a polymer.

How is rubber processed?

Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and ...
