Rubber and its Types | Chemistry Learning
Rubber is a natural polymer of Isoprene (2-Methyl -1, 3 – Butadiene). It is a linear, 1, 4 – addition polymer of Isoprene. Natural rubber has elastic properties and it undergoes long range reversible extension even if relatively small force is applied to it.

Collision and its Types | Chemistry Learning
Consider an example when a rubber ball from a height is dropped on floor and if a collision between ball and floor is elastic then there is no loss of kinetic energy and the ball will attain its original height after rebound. But we find that rebound height is shorter than actual height so we can say collision is inelastic.

Natural rubber
Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex
