In general, raw rubber undergoes washing and refining before being mechanically treated to achieve the necessary plasticity. Subsequently, vulcanizing agents, iron oxide pigments, zinc oxide, calcium carbonate, and other fillers are added under controlled conditions to form the rubber compound. This compound is then reprocessed and molded into various rubber products.

In plastics, iron oxide pigments are used in products such as asbestos-reinforced plastic brake pads. These are produced by mixing resin, asbestos, and iron oxide pigments, adjusting viscosity with a solvent, kneading, and drying. The mixture is then placed into a press to form asbestos plastic components, which can also be used in wood-grain decorative papers.

For coloring PVC plastics with iron oxide pigments, the following method is applied:

First, the iron oxide pigment and plasticizers (such as zinc phthalate) are blended into a thick paste. The ratio varies—commonly 2:1, 1:1, or 1:0.5—depending on oil absorption. This paste is ground using a roller mill or a three-roll mill, producing a dispersion suitable for either transparent or opaque film.

Next, the color paste is mixed with other components according to the film formulation until a uniform consistency is achieved, free of color streaks, spots, or specks.

The tinted PVC slurry is then applied evenly onto a glass plate using a coater. After settling, drying, and deaeration, it is placed in an oven at 180°C for plasticization. After approximately 10 minutes, it is removed and cooled, resulting in a transparent or colored PVC film.
