Abstract (en)
[origin: WO2021025578A1] The inventions relate to composite materials based on mixtures of polyethylene of various structures having improved compatibility of the components. The composition is used in the construction, transport, cable and pipe industries, in the production of packaging materials and products obtained by foaming. The polyethylene composition contains in wt.%, based on the total weight of the composition 20-84 low-density polyethylene (LDPE), 10-70 high-density polyethylene (HOPE), 5-25 linear low-density polyethylene (LLDPE), 0.5-10 polypropylene (PP) and 0-20 other additives. The inventions provide the production of compositions based on polyethylene mixtures with increased melt strength, which allows to obtain products by foaming, as well as improved deformation and strength properties, surface hardness and heat resistance.
