who elastomers extend up to ten times

Ranjeet Sah said: (Aug 7, 2013)  
There is necessary to extend ten times.

Please Describe Elastomers?

What does elastomers mean?

What are elastomers mean?

Rox said: (Nov 22, 2013)  
ELASTOMER - material with elastic properties: a natural material such as rubber or a synthetic material such as polyvinyl that has elastic properties.

Dhana said: (Dec 9, 2013)  
What is the use of elastomer?

Aksh said: (Jan 19, 2014)  
Where are they needed?

Rakesh said: (May 11, 2014)  
How will you say that elastomers extend upto ten times of its initial state?

Amit Karn said: (Jun 28, 2014)  
How can you say that elastomer can extend up to ten times of their original dimensions?

And tell me. What are its other properties of having such a benefit to it?

Ramya(Iikgp) said: (Jul 14, 2014)  
Just you cut elastic band, make a tension force, & analyze yourself.

Ravi Mehta said: (Jul 28, 2014)  
An 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.

Irfan said: (Aug 3, 2014)  
Where is the use of elastomer?

Anil Kumar said: (Feb 11, 2015)  
Can any one explain briefly about elastomers and its applications in?

Abhay said: (Jun 11, 2015)  
Elastomer materials are those materials that are made of polymers that are joined by chemical bonds, acquiring a final slightly cross linked structure.

The main characteristic of elastomer materials is the high elongation and flexibility or elasticity of these materials, against its breaking or cracking.

Amitha said: (Jun 17, 2015)  
Elastomer is used as bearing pad in the bridges to take care of vibrations and expansions.

Sharat said: (Jul 25, 2015)  
Where they are used?

Mithun said: (Aug 2, 2015)  
Rubber band is an example of Elastomers. Rubber band could be stretched long absolutely 10 times.

Piyush Singh said: (Sep 3, 2015)  
Elastomer are the material with fibres which can extend upto 10 times their dimension and they can revert to their original dimension when the stress is released and hystersis loop is formed,

Elastomers are used in bridge girder support like neoprene bearing pad, also for the base isoloation in earthquake proof building neoprene bearing is used.

Dinesh said: (Sep 12, 2015)  
Can anyone tell me what is elastomer and polymer?

Fiaz Hussain said: (Oct 28, 2015)  
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.

Shahsank Tyagi said: (Dec 23, 2015)  
Okay 10 times but why?

Mohammed Sheik said: (Jun 2, 2016)  
Where we use these elastomers in practical allocation?

Vinayak said: (Aug 25, 2016)  
Explain it briefly.

Pabitra Hadu said: (Oct 24, 2016)  
What are the components of elastomers?

Sunil Kumawat said: (Nov 5, 2016)  
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-.

Sujeet Keshari said: (Sep 2, 2017)  
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.

Vip said: (Feb 10, 2018)  
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.

Rabindra said: (Apr 10, 2018)  
Rubber is the example for this.

Smritikana said: (Aug 11, 2018)  
It should be ten. I agree with the given answer.

Injamul Hoque said: (Jul 12, 2019)  
The elastomer can stretch more than two times of their original dimension it means the answer should be three times.
