  1. Natural rubber consists of basic material latex, which a dispersion of isoprene
  2. Natural rubber is made from the saps of a wide range of plants like havea brasillians and gauyule, found in tropical and semi-tropical countries.
  3. The rubber latex is obtained by making incisions in the bark of the rubber trees and allowing the saps to flow out into small vessels.

  1. Drawbacks:
    • Natural rubber does not perform well when exposed to chemicals and petroleum derivatives, including petrochemicals
    • It is not recommended for outdoor applications where maximum resistance to sunlight, ozone or hear aging is major factor
    • Its plasticity is greater than elasticity. It cannot sustain stress. Thus, when stretched to a great extent, it undergoes deformation permanently.
    • It has large water absorption tendency, which makes it weak.
