Lupolen 4021 K RM

Technical Datasheet | Supplied by LyondellBasell

Lupolen 4021 K RM is a UV-stabilized, high density polyethylene (HDPE) grade. Exhibits high environmental stress cracking resistance (ESCR), low temperature impact resistance, good processability, low warpage and resistance against harmful effect of biodiesel fuel. Shows grease- , corrosion- and shatter resistance and high crystalinity. Designed for rotational molding process. Recommended for fuel tanks, heating oil tanks, intermediate bulk container (IBCs), tanks and underground and infrastructure applications. Complies with U.S. FDA 21 CFR 177.1520(a)(3)(i) and (c)3.2a, EU Regulation 10/2011/EC (PIM), EU Packaging and Packaging Waste 94/62/EC and RoHS.
