Document Type and Number:
WIPO Patent Application WO/2019/155152
Kind Code:
A3
Abstract:
The present invention relates to the use of a masterbatch comprising at least one fluorinated compound exhibiting a melting point equal to or higher than 240°C, in particular equal to or higher than 280°C, as determined according to the ISO 11357-3:2013 standard, with a composition comprising at least one polyamide P1 and at least one polyolefin, for reducing die drip during extrusion of the composition and of the masterbatch in the form of a monolayer structure, in particular in the form of a tube or film, while retaining good calibration and good mechanical and thermal properties of the monolayer structure.
