The Origins of Industrial Rubber
1.1 Natural Rubber History
The story of rubber begins with natural rubber, harvested from the latex of the Hevea brasiliensis tree. Indigenous communities in South America first used rubber centuries ago, and European explorers brought it to the global stage in the 18th century.
By the early 20th century, the rise of the automobile industry (thanks to tires) cemented rubber’s place as a key industrial commodity.
1.2 The Rise of Synthetic Rubber
World War II caused a shortage of natural rubber, prompting the invention of synthetic rubber. Today, synthetic varieties (such as SBR, Nitrile, and EPDM) dominate industrial applications due to:
-
Greater chemical resistance
-
Wider temperature tolerance
-
Consistent quality and scalability
2. Types of Industrial Rubber

-
Good abrasion resistance
-
Used in tires, belts, gaskets
2.3 Nitrile Rubber (NBR)
