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-.

What is Elastomers?

Rubber is the example for this.

It should be ten. I agree with the given answer.

The elastomer can stretch more than two times of their original dimension it means the answer should be three times.

Elastomer is high elastic material used in PIER on Bearing plate (Elastomeric). It can be stretched to 10 time of it's original dimension.

An elastomeric material is any material exhibiting elastic or rubber-like properties.

What is elastomer?

Just you cut elastic band, make a tension force, & analyze yourself.
