FIELD: chemistry.
SUBSTANCE: composition contains polypropylene, a polyolefin elastomer, a filler of biological raw materials, a synthetic filler, and a mineral filler. Moreover, as the polypropylene in the composition, primary polypropylene, secondary polypropylene, or a combination of primary and secondary polypropylene can be used. A milled coconut shell, wood fibre, or agave fibres can be used as a filler from the biological raw materials in the composition. Also, a reinforcing agent, a nucleator, and a melt flow enhancer may be included to improve performance and product processing.
EFFECT: composition according to the invention has a good balance of properties, such as density, stiffness, impact strength, and low coefficient of thermal expansion.
