Masterbatch (MB) is a solid or liquid additive for plastic used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.

Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved.In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end without need of adding acid or salt solution or other coagulation step. The coagulated elastomer and particulate filler composite is fed into the aforesaid continuous compounder for processing and control of its moisture level and Mooney Viscosity. Novel elastomer composites are produced. Such novel elastomer composites combine material properties and characteristics, such as choice of filler, elastomer, level of filler loading, moisture level, Mooney Viscosity, balance between molecular weight and amount of bound rubber, and macro-dispersion not previously achieved.

The component particles are repeatedly mixed, compressed, and sheared. Smaller activating component particles coat the surface of larger oxidizing component particles by force-induced contact, while irregularities are removed by abrasion among the particles.

The synthetic organosilicon leather comprises vinyl polysiloxane gum, white carbon black, a structured treatment agent, a plastifying agent, an inhibitor, hydrogen containing silicone oil, a platinum catalyst and silicone rubber masterbatch. The method for producing the synthetic organosilicon leather comprises the following steps: mixing the raw materials to obtain solid mixed silicone rubber through vulcanization via addition, rolling the solid mixed silicone rubber by a multi-roll rolling machine to fit textile-based fabric, heating and vulcanizing to form the synthetic organosilicon leather. The environmental-friendly synthetic organosilicon leather is efficiently produced with a simple process and can be produced on a large scale. The produced synthetic organosilicon leather has good mechanical properties and excellent characteristics of being resistant to high andlow temperature, weathering aging and physical inertia, is easy to cut and sew and is waterproof and breathable. The combustion and decomposition product of the synthetic organosilicon leather contains no harmful substance, can be recycled and accords with environmental protection requirements.
