Rubber elasticity - Know More

Rubber elasticity refers to a property of crosslinked rubber it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length This can be repeated many times with no apparent degradation to the rubber Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and ....
