Natural Rubber and Synthetic Rubber Preparation and Properties

This latex rubber is mainly found in the countries like Brazil, India, Indonesia, Malaysia and Sri Lanka. It is made by the polymerization of isoprene (2 methyl-1, 3-butadiene) which has a chemical formula (C 5 H 8) n and it is known as cis- 1, 4- polyisoprene. In simple words, we can say that they are made by loosely joining the monomers of ...

Elongation is defined as the percentage increase, or strain, in the original length of a rubber sample with the application of a tensile force, or stress. Certain elastomers tend to stretch more compared to others. Natural rubber, for instance, can stretch up to 700% prior to reaching its ultimate elongation, which causes it to break.
