What is the Difference Between Natural and Synthetic Rubber?

Natural and synthetic rubber differ in their production processes, properties, and applications. Here are the main differences between the two:

1. Production: Natural rubber is produced from the latex of trees, primarily the rubber tree (Hevea brasiliensis). Synthetic rubber, on the other hand, is artificially produced from various polymers.
2. Properties: Natural rubber has higher tensile strength, higher tear resistance, and lower odor compared to synthetic rubber (specifically synthetic polyisoprene, abbreviated IR). Synthetic rubber generally has better temperature resistance, aging resistance, and abrasion resistance.
3. Biodegradability: Natural rubber is biodegradable, while synthetic rubber is not.
4. Applications: Natural rubber is often used in products that require high tensile strength and tear resistance, such as tires, gloves, and tubing. Synthetic rubber is used in a wide range of products, including wetsuits, balloons, protective gear, shoe soles, and rubber bands. It can also be tailored to have specific properties, such as chemical, fluid, ozone, and electrical resistances.
5. Cost: Synthetic rubber is usually cheaper to produce than natural rubber. However, the price of natural rubber can be more variable due to factors such as harvesting and agricultural constraints.

In summary, both natural and synthetic rubbers have their own advantages and disadvantages, making them suitable for different applications and industries. The choice between the two depends on factors such as desired properties, cost, and environmental considerations.

Comparative Table: Natural vs Synthetic Rubber

The main difference between natural and synthetic rubber lies in their source, properties, and applications. Here is a table comparing the two types of rubber:

Natural rubber is a good all-rounder, offering a balance of properties, while synthetic rubbers can be tailored to specific applications by varying their composition and production process.
