History of Naturel Rubber: Latex

Natural rubber, also known as latex, is a polymer that is produced by certain plants, primarily trees in the Hevea genus. It has been used by humans for thousands of years, with the ancient civilizations of the Mayans and Aztecs being some of the first to utilize it.

The earliest known use of natural rubber was by the indigenous people of the Amazon rainforest, who used it to make balls for a variety of games, as well as to create waterproof clothing and footwear. The properties of natural rubber, such as its elasticity and durability, made it an ideal material for these purposes.

The first recorded encounter with natural rubber by Europeans occurred in the early 16th century, when Spanish conquistador Francisco de Orellana encountered indigenous people playing with rubber balls during his exploration of the Amazon rainforest. The material was brought back to Europe, where it was initially used for a variety of novelty items, such as erasers and toys.

It wasn't until the 19th century that natural rubber began to be used more widely in a variety of industrial and commercial applications. The demand for rubber began to increase as new technologies, such as the steam engine, became more prevalent. Rubber was used to create seals and gaskets for steam engines, as well as to make hoses and belts for a variety of machinery.

One of the key figures in the history of natural rubber was Charles Goodyear, who is credited with the discovery of the vulcanization process in 1839. Prior to vulcanization, natural rubber was prone to melting in hot weather and becoming brittle in cold weather, making it difficult to use in a variety of applications. Goodyear's discovery, which involved heating natural rubber with sulphur and other chemicals, made it possible to create a more stable and durable form of rubber that could be used in a wider range of temperatures.

The demand for rubber continued to grow in the late 19th and early 20th centuries, leading to the development of large-scale rubber plantations in countries such as Brazil and Indonesia. These plantations relied heavily on the labour of indigenous people and African slaves, leading to widespread exploitation and abuse.

In the early 20th century, the development of synthetic rubber alternatives, such as neoprene and Buna-S, further fuelled the demand for natural rubber. However, the demand for natural rubber declined significantly during the two World Wars, as synthetic rubber was able to meet the needs of the military and industry.

Today, natural rubber is still an important commodity, with the majority of it being used in the production of tires for vehicles. It is also used in a variety of other applications, including medical devices, adhesives, and sporting goods. Despite the development of synthetic alternatives, natural rubber remains popular due to its unique properties and its sustainability as a renewable resource.
