Drawbacks of natural rubber:

Natural rubber is an elastic material obtained from the latex sap of trees. 

An incision would be made into the bark of the tree and the latex sap collected and refined into an appropriate rubber. Rubber are polymeric materials endowed with the properties of flexibility and extensibility.

• Latex contains proteins that can cause severe allergic response.
• Poor resistance to chemicals.
• It cannot resist strong acid and oil.
• It is easy aging.
• Its resistance to weather and ozone is poor.
• It has very less resistance to radiation.
