FIELD: chemistry.
SUBSTANCE: invention relates to polypropylene compositions used to make articles by pressure moulding. The composition contains a polypropylene homopolymer, a block copolymer of propylene and ethylene, a copolymer of ethylene and vinyl acetate and mineral filler.
EFFECT: combination of components in a certain ratio enables to produce a polypropylene composition which is characterised by improved physical and mechanical properties and is used to produce articles which are used in a wide operating temperature range.
