The present invention relates to a multi-layer polypropylene film comprising: A base layer of polypropylene (); Optionally, a tie layer () comprising a blend of polypropylene and an sacrificial engineering thermoplastic; A top layer () comprising film having a structured surface with water contact angles (WCA) superior to 104.5°, preferentially superior to 110°, more preferentially uperior to 120°, more preferentially superior to 130°; Wherein the top layer comprises a blend 20 to 40 wt % of polypropylene and 60 to 80 wt % of said engineering thermoplastic and in which the engineering thermoplastic has been selectively etched in order to create the said structured surface.

Polypropylene film with increased hydrophobicity

A pipe- or tube-shaped article having an innermost layer, wherein the innermost layer has a thickness of 0.001 to 100 mm and comprises a polyolefin composition comprising a) a propylene-ethylene copolymer, wherein the amount of repeat units derived from ethylene is 1 to 20 wt % based on the weight of the propylene-ethylene copolymer and wherein the propylene-ethylene copolymer has a density of at most 0.9 g/cm3 as determined by ASTM D1505 and b) an olefin polymer selected from high-density polyethylene (HDPE), linear low density polyethylene (LLDPE), polypropylene (PP) and combinations thereof.

Pipe with high abrasion resistance

The invention relates to a composition comprising: (A) a propylene-based polymer which is a propylene homopolymer or a propylene copolymer consisting of at least 90 wt % of propylene monomer units and at most 10 wt % of ethylene monomer units and/or an &#x3b1;-olefin monomer units having 4 to 10 carbon atoms, (B) a terpolymer of propylene, an &#x3b1;-olefin having 4 to 10 carbon atoms and ethylene and (C) a copolymer of ethylene and an &#x3b1;-olefin having 4 to 10 carbon atoms, wherein the copolymer (C) has a density of at least 0.880 g/cm, wherein the amount of the propylene-based polymer (A) is at least 60 wt % with respect to the total composition.
