Zeopol brand fillers are highly dispersible, precipitated amorphous silicon dioxides (HDS) utilized in all types of rubber applications. J.M. Huber, Engineered Materials Sector engineered a patented silica production method to manufacture a unique and very special silica filler to enhance the properties of the "green tire" being pursued by all the major tire manufacturers. The resultant silica has successfully contributed to superior processing and performance characteristics when compared to conventional grade silica in tire and other compounds and is currently available to all markets of the rubber industry. Improved properties include: lower processing viscosities, enhanced tear, fatigue, abrasion and hysteresis (heat build-up) resistance. Zeopol products are packaged in a low dust granular form.
