Rubber oil

Both side groups and carbon-carbon double bonds can be incorporated into the polymer structure to produce highly resilient rubbers. Two typical examples are polyisoprene and polychloroprene rubbers. On the other hand, the incorporation of polar side groups into the rubber structure imparts a dipolar nature which provides oil resistance to these rubbers. Oil resistance is not found in rubber containing only carbon and hydrogen atoms (e.g. natural rubber). Increasing the number of polar substituents in the rubber usually increases density, reduces gas permeability, increases oil resistance and gives poorer low-temperature properties. 

Chemistry of SBR. There are three steps in the manufacturing of SBR polymerization, monomer recovery and finishing. The polymerization step determines the basic characteristics of SBR, whereas the product form (latex or dry rubber, oil extended or not) depends on the finishing step.

These products are separated by distillation and used to make over 500 million Kg per year of silicone rubbers, oils, and resins. All of these materials repel water and are electrical insulators. The rubbers are flexible and the oils are liquids over a wide range of temperatures. 

Knowledge of the physical state of oil in oil-extended rubbers and their vulcanisates is of great importance, because the processing of oil-extended rubbers and the mechanical properties of such rubbers are strongly affected by the rubbers oil content and the type of oil concerned.

Rubbers are further classified according to application as all-purpose rubbers, oil-resistant rubbers, and heat-stable rubbers. About half of rubber production is used to make tires and the other half is used for commercial rubber articles. 

Refers to an empirical analysis of rubber process oil composition that expresses the percentages of carbon atoms in aromatic, naphthenic, and paraffinic components, respectively. See Rubber Oil, Aromatic, Naphthene, Paraffin. 

Any petroleum process oil used in the manufacture of rubber and rubber products. Rubber oils may be used either as rubber extender oils or as rubber process oils. Rubber extender oils are used by the synthetic rubber manufacturer to soften stiff elastomers and reduce their unit volume cost while improving performance characteristics of the rubber. Rubber process oils are used by the manufacturer of finished rubber products (tires, footwear, tubing, etc.) to speed mixing and compounding, modify the physical properties of the elastomer, and facilitate processing of the final product.
