SEMICONDUCTING POLYMER COMPOSITION Russian patent published in 2023 - IPC C08L23/08 C08L31/04 C08K3/04 H01B3/44 

FIELD: semiconductive polymer composition.

SUBSTANCE: present invention is related to a group of inventions: a semiconductive polymer composition, a product, a method for producing a semiconductive polymer composition, a method for producing a cable, and the use of polyethylene wax. The semiconductive polymer composition contains an ethylene-vinyl acetate copolymer base polymer, at least 25 wt.% carbon black, 5-15 wt.% polyethylene wax, and 0.1-5 wt.% acid absorber. Semiconductive polymer composition is obtained by mixing the components in a mixing equipment. Polyethylene wax is used to reduce energy consumption when mixing a semiconductive polymer composition. The product is a layer in a multilayer cable or a cable. The method for producing a cable includes applying to one or more conductors a layer containing the semiconductive polymer composition.

EFFECT: development of a semiconductive polymer composition providing lower energy consumption during mixing without loss of mixing performance.
