Formula & Raw Materials

Every rubber compound is made up of natural and synthetic rubbers - along with many other solid and liquid ingredients. Carbon black, silica, silanes, oils, sulphur anti-oxidants to name just a few... The quality of all these raw materials determines whether a tyre will be outstanding or just mediocre. There are countless options for selecting, combining and measuring them, so a good formula requires highly specialised expertise, high-quality raw materials and extrensive testing - it goes without saying that the final recipe is top secret.
