Lonza's leaders decided to build their own cracker in Visp to break down gas or petrol into major petrochemical building block chemicals such as ethylene and hydrogen, greatly expanding Lonza's product portfolio. These petrochemicals were widely in demand for many end-use products, including clothing, housing, mobility or personal care items.
In 1965 the world's smallest industrial naptha cracker came on line at the Valais Works.
Cracker products are the building blocks of the chemical industry and the starting materials for numerous processing industries. These basic products for the processing industry are used in end products that help to meet demand for clothing, food, housing, and mobility as well as medication and personal care items.
