Methods to prepare elastomer compounds are described that include dry mixing at least one additive to an elastomer composite masterbatch at low temperatures over a shortened mixing cycle with reduced energy consumption. The elastomer composite masterbatch is produced in a liquid masterbatch process. The resulting elastomer compounds are further described as well as property improvements that can be achieved.

Methods of producing an elastomer compound and elastomer compounds

A silica elastomer composite having superior mechanical properties.

Elastomer compounds reinforced with silica and products containing same

Methods to make a silica and carbon black elastomer composite with a destabilized dispersion that includes silica are described, along with particle reinforced elastomer composites made from the methods. The advantages achieved with the methods are further described.

Methods to make a silica elastomer composite with a destabilized dispersion of silica are described, along with silica elastomer composites made from the methods. The advantages achieved with the methods are further described.

Methods of making an elastomer composite reinforced with silica and products containing same

Methods to make a silica elastomer composite with a destabilized dispersion of a never-dried, or as-produced, precipitated silica are described, along with silica elastomer composites made from the methods. The advantages achieved with the methods are further described.

Blends of elastomer composites with unfilled or less highly filled elastomer reduces hysteresis without compromising reinforcement. Hysteresis may also be reduced by adjusting the compounding method.

Elastomer composites, blends and methods for preparing same

Disclosed herein are activated carbon having a particle size distribution of dranging from 1 &#x3bc;m to 28 &#x3bc;m and a d/dratio ranging from 1.5 to 3, compositions comprising such activated carbons and methods of making the same, and methods of mercury removal from flue gas generated from coal combustion by injecting activated carbon into the flue gas.
