METHOD OF MANUFACTURING FILLER-CONTAINING POLYMER SHEET Russian patent published in 2018 - IPC B29C53/04 

FIELD: technological processes.

SUBSTANCE: method of manufacturing polymer sheet contains a stage of bending that includes bringing a billet of the polymer sheet containing a filler in the amount of 50% or more and 85% or less in contact with the surface of a solid body in such a way that the sheet is pressed the solid body surface in the transverse direction relative to the direction of the production flow while moving the sheet during the extraction towards the production flow, ensuring the sheet bend in the contact area to create a tension, which affects the internal side of the sheet.

EFFECT: increasing the physical and mechanical properties of the products.
