Microthene®
Premium polyethylene powders engineered for rotational molding and specialty applications
About Microthene®
Microthene® is LyondellBasell's flagship line of polyethylene powders, widely recognized as the industry standard for rotational molding applications. These finely pulverized powders offer exceptional flow and consistent particle size distribution, enabling uniform wall thickness and superior surface finish in molded parts.
Available in a broad range of densities and melt indexes, Microthene® powders are engineered to meet the demanding requirements of rotational molders. Grades span from linear low-density polyethylene (LLDPE) for flexible, impact-resistant parts to medium-density polyethylene (MDPE) and high-density polyethylene (HDPE) for rigid, structural applications.
Microthene® powders are also used in masterbatch production, carpet backing, coatings, and other specialty processes where fine particle size and uniform melt behavior are critical. FDA-compliant grades are available for food contact and potable water applications.
