tw <br />E*,,pnMobil <br />Exxon o i <br />Linear Low Density Polyethylene <br />LL-8400 Series rotational Molding Grades <br />Description <br />ExxonMobil LL-8400 series are linear <br />medium density polyethylene resins that <br />provide outstanding environmental stress <br />crack resistance. They are well suited for <br />the rotomolding of parts that require a <br />combination of good flow characteristics, <br />stiffness and good low temperature <br />toughness. <br />Typical Applications <br />• Septic tanks <br />• Chemical storage bins <br />• Rotomolded pallets <br />• Potable water tanks <br />LL-8401 Base resin with oxidation <br />protection only in pellet form. <br />LL-8460 Fully formulated long term UV <br />stability package in pellet form. <br />LL-8461 Fully formulated long term UV <br />stability package in ground form. <br />Resin Properties <br />Test Based On' <br />Unit <br />Typical Value' <br />Melt Index <br />Density <br />ASTM D-1238 <br />ASTM D4883 <br />g/10 min. <br />g/cm3 <br />3.3 <br />0.938 <br />Melting Point <br />ExxonMobil Method <br />°C <br />126.5 <br />Molded Properties' <br />Yield Tensile Strength <br />ASTM D-638 <br />MPa (psi) <br />17.9 (2,600) <br />Elongation @ Break <br />ASTM D-638 <br />% <br />765 <br />Flexural Modulus, 1% Secant <br />ASTM D-790 <br />MPa (psi) <br />613 (89,000) <br />Impact Strength <br />Max.

Values given above are typical and should not be used as specification limits. <br />2. All physical properties were measured on rotomolded specimens. <br />3. Tensile testing was conducted at a crosshead speed of 50 mm/min. The tensile strength reported <br />refers to the maximum load reached during the test <br />4. ASTM test procedures may be modified to accommodate operating conditions or facility limitations <br />Food Packaging <br />LL-8400 series grades are olefin copolymers which comply with FDA Regulations 21 CFR 177.1520 (c) <br />3.1 and 3.2, and may be used in articles which are intended to contact food. Health and Welfare <br />Canada has no objection to the use of these resins in food packaging. The finished article is subject to <br />certain additive -related volume (5 U.S. gallon minimum) and temperature (Maximum: 150°F (U.S.) or <br />120°F (Canada)) restrictions.
