POLYMER COMPOSITE Russian patent published in 2022 - IPC C08L23/04 C08L23/10 C08K3/36 C08K3/13 

FIELD: polymers.

SUBSTANCE: invention relates to mineral polymer composite materials based on thermoplastic polymers operating in high humidity and variable temperatures, and exhibiting improved operating properties. Polymer composite according to the invention includes a low-pressure polyethylene in an amount of 20 to 80 wt.%, dye in an amount of 1 to 5 wt.%, polyethylene wax in an amount of 1 to 5 wt.%, and kieselgur powder with a bulk density of 0.2 to 0.65 g/cm³ and a particle size of 0.5 to 500 mcm the rest.

EFFECT: claimed mineral polymer materials are characterised by lower density and higher strength.
