We use aromatic residues to take you far and create products close to you
We are present in various industry processes and present in various products in your daily life. Aromatic residues — or RARO — are used as an industrial raw material to obtain carbon blacks, used in the composition of the most varied products in the plastics, tires, rubber artifacts, and paints industries that are present in most of the products we use on a daily basis.
Petrobras RARO was developed with technology and quality from the heaviest fractions originating from the Catalytic Cracking Units (UFCC). Therefore, it presents:
-
High content of aromatic hydrocarbons.
-
High carbon/hydrogen ratio.
-
High density.
The solution specifications can also be adjusted, upon request, to meet the specific needs of customers.
Main applications
Petrobras RARO is the raw material of the carbon blacks, produced at our customers from the incomplete combustion of aromatic fillers. Normally, they have a carbon content above 95% and contain minimal amounts of nitrogen, oxygen, and hydrogen.
Carbon blacks are agglomerates of elemental carbon with the consistency of an impalpable powder, with different morphologies (particle size, structure, porosity, and physical form) and chemical treatments, offering the correct performance for each application.
They have a high pigmenting power, high purity, and low moisture content, which ensures black color, provides resistance to ultraviolet rays, and increases the mechanical strength of materials. See some uses of carbon black:
É o pigmento que garante a cor preta dominante em boa parte dos produtos. Evita a deformação (maleabilidade) e reduz o peso de materiais que necessitam ser submetidos a grandes e/ou continuados esforços.
Aqui, o equilíbrio entre durabilidade e aderência são os vetores de projeto. Para isso, os negros de carbono garantem a resistência à abrasão para a banda de rolagem — parte que fica em contato com o solo — e à flexão para a carcaça.
É utilizado na obtenção do preto intenso e no tingimento de outras cores, conferindo a viscosidade, pigmentação, brilho, subtom e poder de cobertura apropriados conforme a aplicação.

It is the pigment that guarantees the dominant black color in most products. It avoids deformation (malleability) and reduces the weight of materials that need to be submitted to great and/or continuous efforts.
Here, the balance between durability and grip are the design vectors. For that purpose, carbon blacks ensure resistance to abrasion for the tread — the part that is in contact with the ground — and resistance to bending for the carcass.
It is used to obtain intense black and to dye other colors, providing appropriate viscosity, pigmentation, brightness, undertone, and covering power according to the application.
