Main Difference

The main difference between Natural Rubber and Synthetic Rubber is that the Natural Rubber is the natural polymer that is derived from a tree named Hevea brasiliensis, whereas Synthetic Rubber is the artificial polymer that is made under different conditions.

Natural Rubber vs. Synthetic Rubber

Natural rubber is the natural polymer; on the other hand, synthetic rubber is an artificial polymer. The natural polymer is derived from a unique plant named Hevea brasiliensis; on the flip side, synthetic rubber is the polymer that is made in the laboratory under specific conditions. Natural rubber always found in the plant cells; on the opposite side, synthetic rubber always made by different techniques of polymerization and emulsions.

Natural rubber is made by the polymerization of cis-1,4-isoprene monomer; on the other side of the coin, synthetic rubber is the artificial polymer that can be made by the polymerization of different monomers in different rubbers. The quality and content of the natural rubber changes according to the weather, soil type, clone, and geographical area; on the other hand, synthetic rubbers can be made of different quality and contents with very little impurities.

As the natural rubbers are natural, their properties cannot change; on the flip side, synthetic rubbers are made according to the application. Natural rubbers are very costly; on the opposite side, synthetic rubbers are less costly. The natural rubber has more temperature resistance; on the other hand, synthetic rubbers are more temperature resistant. The quality of natural rubber is much better than synthetic rubber. Natural rubber is not much specific to meet the performance in comparison to the synthetic rubbers.

What is Natural Rubber?

Natural rubber is the natural that is found only in plant cells named Hevea brasiliensis. It is not much specific in nature to its required performances. Its cost is also much high as it is found in nature. It is not of high quality but also does not have any temperature resistance. As it is found in nature, not a human-made its properties, and features are not variable. Natural rubber is formed by the polymerization of a single monomer name cis-1,4-isoprene.

Its quality is variable according to the clone, soil type, weather, and geographical area. Natural rubber only has its different latex variety. Natural rubber contains very high tensile strength and also have any structure regularity. The natural rubber also has a high vulcanization rate. Natural rubber also has many benefits and used in many industrial applications.

The features of natural rubber are very different from the synthetic rubber as it has high abrasion resistance, have excellent low-temperature properties, has an ability to bind with metal parts, having excellent dynamic properties, low hysteresis loss, low level of damping, excellent dynamic performance, ease of processing, and low heat buildup during heating. The natural rubber has many applications, including seals, rubber gaskets, vibration isolators, shock mounts, electrical components, hoses and tubes, and drive couplings, etc. Natural rubbers also have good resilience and physical strength and inferior oil resistance.

What is Synthetic Rubber?

Synthetic rubber is artificial that is not found in nature and prepared in the laboratory. It is always made specific according to its required performances. Its cost is not much high as it is made by man. Its quality and content are high and also have temperature resistance as it is artificial so that it can be made with required variable properties and features. Synthetic rubber is made by the polymerization of specific different monomers in each type.

It has high quality according to the need with very little impurities. It can be made with different latex variety. Synthetic rubbers are generally the side products of oil production. Synthetic rubbers have chemical, temperature, excellent weather, and solvent resistance. Some of these also have oil resistance and resistance against ozone, oxygen, oxygen, certain chemicals, and a wide range of temperatures. Each synthetic rubber has its own specific and unique properties.

Synthetic rubbers usually include 20 different types of classes that have unique features and characteristics. Synthetic rubbers also do not have useful gas permeability.

Key Differences

  1. Natural rubber is derived from nature; on the other hand, synthetic rubber is artificial and human-made.
  2. Natural rubber always found from the plant named Hevea brasiliensis; on the opposite side, synthetic rubber always human-made and prepared in labs.
  3. The cost of natural rubber is very high; on the flip side, the cost of synthetic rubbers are not very high.
  4. Natural rubbers do not have any temperature resistance; on the other side of the coin, the synthetic rubbers can be made resistant against temperature.
  5. The natural rubber is just found in nature and does not have any specificity towards its required performance; on the other hand, synthetic rubbers are always made specific to its required performance.
  6. The quality of natural rubber varies according to the clone, geographical area, soil type, weather, etc.; on the other hand, synthetic rubber always made of high quality according to the need with very low impurities.
  7. Natural rubber is made by the polymerization of monomer cis-1,4-isoprene, but in its comparison, synthetic rubber is a variable that is made of different monomers in each type.
  8. Natural rubber is natural, so its properties cannot be changed; on the other hand, synthetic rubber is artificial so it can be made according to the desired properties and features.
  9. Natural rubber always formed in plant cells with variable latex; on the flip side, synthetic rubber always made by the polymerization processes.

Conclusion

The above discussion concludes that natural rubber is derived from the plants; on the other hand, synthetic rubber is the man-made that is prepared in the labs according to certain conditions.
