The properties of oil-resistant black NBR rubber

The main characteristics of oil-resistant black NBR rubber

The oil-resistant black NBR rubber is one of the most used solutions on an industrial level. Therefore, it is a highly sought after and appreciated product. This happens because it is a material that does what it promises, proving to be a great help for those who work in certain contexts, productive and otherwise. To know its properties, it is useful to start from the assumption that currently there are two types of rubbers on the market: there are natural ones and also synthetic ones.

The natural ones are made by coagulating the latex obtained from the Hevea brasiliensis plant and other tropical plant species. After careful processing, we arrive at the production of a material with excellent mechanical characteristics. On the other hand, however, it is not very resistant to atmospheric agents, various chemicals, high temperatures and has poor resistance to oils. After contact and / or immersion, the oil penetrates into the polymer matrix and partly dissolves it, partly swells it. The object therefore loses its characteristics.

To make up for these shortcomings, synthetic rubbers have been developed and NBR rubber is one of them. Also known as nitrile rubber, it is resistant to oils and fuels and has good mechanical properties.

Synthetic rubbers and their characteristics

Synthetic rubbers can therefore withstand atmospheric agents, high temperatures and numerous chemical compounds. To produce them, we start with the processing of simple hydrocarbons and the polymerization of some artificial latexes. After the execution of specific production processes, different types of rubbers are obtained, such as the oil-resistant black NBR rubber. These materials have many properties in common, such as those listed above, but also different mechanical and chemical characteristics.

Synthetic rubbers have been divided into five groups called M, O, Q, R and U, which differ from each other based on the composition of the polymers present in the rubber itself. NBR rubber is part of the R group, which includes products composed of polymers containing unsaturated carbon. Generally, this material ensures a maximum operating temperature of 100 ° C, while the minimum is -20 ° C. It boasts good machinability in terms of milling, cutting and drilling.

As anticipated, the oil-resistant black NBR rubber is resistant to oils, animal fats and minerals. For all these reasons, it is suitable for industrial use, especially in contexts where various types of oils and fats are used.

What else is there to know about oil-resistant black NBR rubber?

It is important to consider that this type of rubber is mainly used indoors or in any case protected from UV rays. It is usually sold in sheets and packaged in sectionable rolls. Thanks to its particular characteristics, the oil-resistant NBR rubber is used for the production of industrial gaskets. It presents itself as the ideal solution for numerous production contexts and is the right supplement for those who want to optimize the performance of their plants and machinery.

Precisely for these reasons, we at Cavallero Gomma know it well and use it for many of our creations. Among the numerous processes carried out within our facility, we perform the shearing of the rubber through the use of traditional or latest generation tools. Our experience and our equipment allow us every time to offer an extremely functional and excellently finished product.
