•The additives must be thoroughly mixed with the base rubber to achieve uniform dispersion of ingredients •Uncured rubbers have high viscosity so mechanical working of the rubber can increase its temperature up to 150 C (300 F) •If vulcanizing agents were present from the start of mixing, premature vulcanization would result -the "rubber processor's nightmare" ©2002 John Wiley

Mixing and mastication are carried out in an Internal Mixer or Kneader or Two Roll mixing mill. Rubber compounding is one of the most difficult and complex subjects to master in the field of Rubber Technology. There is no simple mathematical formulation to help the compounder. That is why compounding is so difficult a task. More on this subject) L&T Marketed Make Internal Mixers

Rubber - Rubber - Processing: Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and (4) curing, when the polymer molecules become

In fact, dry or solid rubber needs to be mixed with the vulcanizing agent and other additives in a two-roll mill, an extruder, or Banbury mixer; then it has to be formed and allowed to vulcanize. In the top-down approach the fillers must be introduced in the matrix during the first step in order to use the shear forces, generated by the mixing process, to disperse or exfoliate the nanoparticles.

In other cases, a chemically homogenous material may be mixed to produce a uniform lot of a desired weight/volume with consistent particle size distribution, color, texture, and other required attributes, e.g. metal powders produced in 1 ton batch size are blended to a homogenous lot size of 4 tons (or pre-specified quantity) . The terms "mixing" and "blending" are often used

25.02.2015· Do you use centrally cored rolls or peripherally drilled rolls in your two-roll mixing mills?Or a combination of both? Roll selection for a mixing mill is of decisive importance for the quality of many high-tech products manufactured by the rubber industry. Open two-roll mills in rubber processing are recommended when quick cooling for the batch being mixed is sought, say for example in final
