Can anyone tell me what is elastomer and polymer?

Polymer is a compound containing carbon chain in their chemical composition while elastomers are those polymers which have elastic properties. Elastomers can be used as joint sealant.

Okay 10 times but why?

Where we use these elastomers in practical allocation?

Explain it briefly.

What are the components of elastomers?

What is elastomer? Please describe it in detail.

Elastomer is a polymer with viscoelasticity (having both viscosity and elasticity) and very weak inter-molecular forces, generally having low Young's modulus and high failure strain compared with other materials. The term, which is derived from elastic polymer, is often used interchangeably with the term rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually made of carbon, hydrogen, oxygen or silicon. Elastomers are amorphous polymers existing above their glass transition temperature so that considerable segmental motion is possible. At ambient temperatures, rubbers are thus relatively soft (E~3MPa) and deformable. Their primary uses are for seals, adhesives and moulded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, shoe soles, and damping and insulating elements. The importance of rubbers can be judged from the fact that global revenues are forecast to rise to US$56 billion in 2020.

Rubber like solids with elastic properties are called elastomers. Polymer chains are held together in elastomers by weakest intermolecular forces. This weak binding forces permit the polymers to be stretched. Natural rubber, neoprene rubber, buna-s and buna-.

Elastomer is a polymeric material. Because of having a long chain of the raw element of organic material it can be stretched to 5 to 10 times of its original dimension.

Elastomer is a high elasticity for other materials it is more fabric and low strength. It can be stretched to 10 time of it's original dimension and weekest inter molecular force.
