FIELD: chemistry.
SUBSTANCE: mineral filler of 150 - 800 pts. wt. for 100 pts. wt. is added to the polymeric material, while the addition of the filler and mixing with the polymer is carried out using direct addition technology and upstream of the mixing zone for producing the masterbatch. The polymeric material includes a polymer selected from the group consisting of vinyl polymers, vinyl copolymers, acrylic polymers, acrylic copolymers, chlorinated polyethylenes, and mixtures thereof.
EFFECT: reducing the time of production and saving energy, producing a high-quality masterbatch.
