Biodiesel no problem for this HDPE

LyondellBasell’s Lupolen 4261AGBD and 4261A IMBD HDPE grades offer good resistance properties to biodiesel when molded into fuel tanks.



LyondellBasell’s Lupolen 4261AGBD and 4261A IMBD HDPE grades offer good resistance properties to biodiesel when molded into fuel tanks.
A new family of Lupolen high-density polyethylene (HDPE) resins offers improved resistance to biodiesel, and therefore is a new candidate for blowmolded and injection molded automotive fuel tanks. Grade 4261AGBD is designated for blowmolding, while 4261A IMBD is suitable for injection molding of vehicle fuel tanks. After 1500 hours of contact with 100% biodiesel fuel, the grades changed their intrinsic viscosity by only 1.7%. This corresponds to a nearly 30-fold improvement in resistance compared to standard HDPE grades previously used for fuel tank applications.
