New Rotors for High Silica Mixing

Tire companies are continually going to higher and higher silica content to achieve improved grip, rolling resistance and durability.  Tangential rotors yield greater output and equivalent performance to the Intermesh rotor up to around 80 phr silica.  Above that level, the Tangential rotor performance begins to fall off.  With silica levels now greater than 100 phr in some applications, a new rotor has been developed for high silica mixing that combines the output of a Tangential rotor with the properties of an Intermesh rotor.
