Natural rubber is an emulsion containing 60-80% water, which flows from the bark. It is located in small particles suspended in the latex, of which it represents 90% of the dry weight. It is a natural polyisoprene.
Advantages of natural rubber
- Excellent mechanical properties.
- Good compression.
- Fairly good resistance to water and non-mineral detergent acids.
- Tear resistance
Limits: poor resistance to UV and hydrocarbon-based solvents (aliphatic and aromatic), oils or petroleum derivatives
