  • Publication number: 20240051221
    Abstract: A process for producing articles with an extrusion-based additive manufacturing system using a consumable filament made from or containing a propylene polymer composition made from or containing: A) from 20% to 60% by weight of a heterophasic propylene copolymer; B) from 5% to 33% by weight of a propylene homopolymer or copolymer, wherein the copolymer contains up to 5% by weight of an alpha olefin; C) from 2% to 15% by weight of an elastomeric block copolymer made from or containing styrene; D) from 4% to 32% by weight of an elastomeric ethylene copolymer; E) from 5% to 50% by weight of a glass material as filler; and F) from 0.1% to 5% by weight of compatibilizer.

  • Publication number: 20230023978
    Abstract: Methods for processing LDPE recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. LDPE recyclate can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed LDPE recyclates. Processed LDPE recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both LDPE recyclate and/or pre-consumer polyolefins.

  • Publication number: 20220259416
    Abstract: An extrusion additive manufacturing process including the step of extruding a polyethylene composition having a melt flow index MIE of at least 0.1 g/10 min., the composition made from or containing: A) from 1% to 40% by weight of a polyethylene component having a weight average molar mass Mw, as measured by GPC (Gel Permeation Chromatography), equal to or higher than 1,000,000 g/mol; B) from 1% to 95% by weight of a polyethylene component having a Mw value from 50,000 to 500,000 g/mol; and C) from 1% to 59% by weight of a polyethylene component having a Mw value equal to or lower than 5,000 g/mol.
