POLYMER COMPOSITION FOR MAKING FRAME OR FACING MATERIAL Russian patent published in 2024 - IPC C08L23/06 C08L23/12 E04C2/20 

FIELD: chemistry.

SUBSTANCE: present invention relates to the field of materials, in particular to polymer compositions used for making frame or facing materials. Described is a polymer composition for making a frame or facing material, which contains high-pressure polyethylene, polypropylene, linear low-density polyethylene, a foaming additive and a light-stabilizing additive, with the following content of components, wt.%: high-pressure polyethylene 65.0-80.0; polypropylene 5.0-20.0; linear low-density polyethylene 0.1-6.0; foaming additive 0.1-6.0; light-stabilizing additive 0.1-3.0. Also described is a polymer composition for making a frame or facing material, comprising low-pressure polyethylene, high-pressure polyethylene, polypropylene, linear low-density polyethylene, a foaming additive, a light-stabilizing additive and a fire-resistant additive, with the following content of components, wt.%: low-pressure polyethylene 0.1-60.0; high-pressure polyethylene 10.0-70.0; polypropylene 5.0-20.0; linear low-density polyethylene 0.1-5.0; foaming additive 0.1-5.0; light-stabilizing additive 0.1-2.0; fire-resistant additive 0.1-2.0.

EFFECT: improving reliability of frame or facing material, as well as reliability and manufacturability of articles made from it.
