  • CLOSURE HAVING EXCELLENT ORGANOLEPTIC PERFORMANCE
    Publication number: 20170342176
    Abstract: A closure comprising a polyethylene copolymer which has a density of from 0.940 to 0.962 g/cm3, a melt index I2 of less 1.5 g/10 min, high levels of unsaturation and low catalyst component residues, has excellent organoleptic properties.

  • Stabilized rotomolded parts
    Publication number: 20100187726
    Abstract: Easy processing rotomolding resins which have a high melt index, I2, (as measured by ASTM D 1238) of from 2 to 10 (especially 3 to 8) grams/10 minutes and a narrow molecular weight distribution, Mw/Mn, of from 2.0 to 3.0 are difficult to stabilize with correctional additive packages. The present invention resolves this problem by the use of from 500 to 5000 parts per million by weight (ppm) of zinc oxide, in addition to a standard stabilizer additive package.

  • Phenol free stabilization of polyethylene film
    Patent number: 7361703
    Abstract: This invention provides a process for the stabilization of thermoplastic polyolefins during melt processing operations. The stabilizer package of this invention is “phenol free” and must contain at least one aryl monophosphite and at least one diphosphite. The process of this invention is especially suitable for the manufacture of polyethylene film.

  • Pipe coating composition
    Publication number: 20070254990
    Abstract: A pipe coating composition comprises a linear polyethylene having a specific melt index and a narrow molecular weight distribution and an additive package comprising a hindered phenolic, a phosphite and a hindered amine light stabilizer. The composition preferably contains carbon black. The composition permits high rates of application and provides good oxidative induction times.
