  • Coated pipe with high throughput using multimodal ethylene copolymer
    Patent number: 8623482
    Abstract: The present invention deals with coated pipes having a layer of multimodal polyethylene. The multimodal ethylene copolymer is a copolymer of ethylene with one or more alpha-olefin comonomers having from 4 to 10 carbon atoms and has a weight average molecular weight of from 70000 g/mol to 250000 g/mol, the ratio of the weight average molecular weight to the number average molecular weight, Mw/Mn, of from 15 to 50, a melt index MFR2 of from 0.05 g/10 min to 5 g/10 min, a melt index MFR5 of from 0.5 to 10 g/10 min and a density of from 930 kg/m to 955 kg/m3.
    Type: Grant
    Filed: December 9, 2008
    Date of Patent: January 7, 2014
    Assignee: Borealis Technology Oy
    Inventors: Martin Anker, Siw Bodil Fredriksen, Pal Christian Bentzrod, Mats Backman, Leif Leiden, Markku Vahteri, Petri Rekonen
  • Coated pipes having improved mechanical properties at elevated temperatures and a method of production thereof
    Patent number: 8142871
    Abstract: The present invention deals with coated pipes having a layer of multimodal polyethylene. The multimodal ethylene copolymer is a copolymer of ethylene with one or more alpha-olefin comonomers having from 4 to 10 carbon atoms and has a weight average molecular weight of from 70000 g/mol to 250000 g/mol and a melt index MFR2 of from 0.05 g/10 min to 5 g/10 min, a melt index MFR5 of from 0.5 to 10 g/10 min and a density of from 945 kg/m3 to 958 kg/m3. The coatings have a high stiffness, good properties at elevated temperatures and acceptable stress-cracking properties.
