LyondellBasell (Rotterdam, Netherlands) has launched two new pre-colored rotational molding resins that provide good cold-temperature impact performance and environmental stress-cracking resistance. The Lupolen 3621 M RM Black and Lupolen 4021 K RM Black high-density polyethylene (HDPE) compounds are suited for industrial fuel tanks, technical parts, and underground waste and sewage systems. The company noted that next to natural, black is the most commonly used color in rotomolding applications. LyondellBasell says the materials offer a combination of impact/stiffness properties, with low-temperature impact performance down to -30°C. Given that, applications produced with these resins should be able to withstand harsh transport conditions in cold weather.
