Our company was originally launched in 1970 in Montcada i Reixac, by Jordi Sans Ripoll.

Since 1982, the company settled in Cerdanyola del Valles under the name of Cauchos del Vallés S.A., led by its founder and his son.

After the founder’s passing, the management of the company passed to his son Jordi Sans Serra, who has been in the business for over 40 years as a manager and as head of production.

Our facilities have more than 800m2, divided into different areas that help us separate work processes. Thus, we can distinguish the storage area; the production’s; the logistics’; the employee’s; and administration area. Despite being a small family business, our facilities allow us to cover a large number of orders, managing them effectively and quickly.



Natural rubber has its origins in Central and South America, a tree known as Hevea (the word "rubber" comes from the Quechua "cautchouc" which means tear-house), where it was collected long before the arrival of the Europeans and their mercantilist zeal. Some Amazonian Indians (the Mayans and Aztecs) used it to make pots and waterproof sheets, and manufactured balls to play "tlachli" (the oldest balls found date from about 1600 BC used by ancient Mesoamerican), the basketball precursor, until the fifteenth century, when the conquerors banned this game, forgetting the rubber for nearly 200 years.

XVIII Century

In the early eighteenth century, in his expedition to the Amazon, the scientist Charles La Condamine discovered the plant and was passionate about its great properties (including its composition by hydrocarbon chains, which left open the possibility of producing synthetic rubber).

The scientific interest in the substance and its properties was revived. They sought for ways to dissolve the latex to be worked away from its natural source, as it quickly hardens after being extracted.

When the first samples came to Spain, it was observed that a piece of the material could be used to erase pencil marks. This was also established in 1770 by the British chemist Joseph Priestley, the same who discovered oxygen.

In 1791, an English manufacturer patented a method of waterproofing cloth by treating it with a solution of rubber in turpentine, which was the first public application for rubber.

XIX Century

As many other great advances in science, vulcanization (a key in the history of rubber progress), was possible thanks to an accident in 1839, by Charles Goodyear, an inventor from Boston, who dropped a mixture of rubber and sulfur on a hot stove. This mixture was hardened and turned waterproof, which he called vulcanization after the god Vulcan. This was the beginning of the vulcanization process, which made rubber immune to the elements, transforming it from rarity to essential product of the industrial era.


From 1925, the process cost was reduced by using butadiene, obtained from petroleum products, which became the main raw material for the production of cheap rubber. Ever since, other synthetic rubber classes were discovered.

Since 1945, the production of synthetic rubber is higher than natural rubber, which has nevertheless remained in the market, as it achieves some importance in times of high oil prices.
