Influence of ionic liquids on rheological behaviors
In the rubber compounds, the molecular structure of ILs influences their wettability to fillers [30,31] and interactions with the rubber matrix [32,33], which could greatly affect the filler dispersion and rheological behavior .

Rubber Compounding - an overview | ScienceDirect Topics
Mill mixing. The second step is the mixing of the treated fiber into the rubber formulation during the rubber compounding operation in an intensive (Banbury) or two roll mills. The product from this step is a homogeneous rubber compound reinforced with fiber. The compound is heated on a mill roll into sheets for handling.

Baypren® CR
Items made of rubber that are in contact with soil for long periods of time are susceptible to attack by soilborne bacteria and fungi. In the long term, this can lead to underground cables, for example, being destroyed. In contrast to the majority of other rubber types, Baypren displays superior resistance to these microorganisms. This resistance can be enhanced still further through suitable compound formulation.

Natural rubber
Natural rubber, also called by other names of India rubber, latex, Amazonian rubber, caucho or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds, plus water. Thailand and Indonesia are two of the leading rubber producers. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree or others. The latex

Online Training | Rubber Division, ACS
During this webinar you will be shown the economic importance to delivering consistent rubber compounds. Consistency begins with the raw material specifications and continues through the storage of the raw materials, extends through the weigh-up and mixing operations and includes the post-mixing operations of milling and preforming.
