Apparatus for mixing polymer, the apparatus comprising (i) a mixer housing including an internal chamber, said internal chamber having first and second sections in fluid communication with each other through a passageway; (ii) a first ram received in said first section; and (iii) a second ram received in said second section, where the apparatus is adapted to receive a composition including polymer within said internal chamber and move said composition between said first and second chambers through said passageway by operation of said first and second rams.

Mixing device and methods of operation

A method for rubber formulating and characterizing, the method comprising (i) providing a plurality of rubber samples including at least three rubber samples each contained within a container; (ii) introducing a compounding additive to at least one of the samples within the plurality of rubber samples to thereby form a plurality of rubber formulations each contained within a container; (iii) mixing at least one of the samples of the plurality of rubber formulations under high-shear conditions to thereby form a plurality of vulcanizable compositions; and (iv) analyzing at least one of the samples plurality of vulcanizable compositions to thereby characterize the compositions of the plurality, where at least one or the plurality of the rubber samples, the plurality of rubber formulations, the plurality of vulcanizable compositions are transferred to a subsequent step through an automated transfer.
