As early as the 11th century, the people of South America began to use wild natural rubber. In 1736, French C Kondamina participated in the investigation team of the French Academy of Sciences to South America, and observed that the latex from the trefoil rubber tree can be cured into an elastic material. Later, the rubber samples of wild rubber trees in the Amazon River Basin were sent back to Paris, which began to attract the attention of Europeans. In 1823, C. mackintosh established the first waterproof tape factory in England. At the same time, t Hancock found that rubber can be processed repeatedly through the gap between two rotating rollers, which can reduce the elasticity and improve the plasticity.
This discovery laid the foundation for rubber processing. He is recognized as the pioneer of the world rubber industry.
