LyondellBasell Microthene^®

LyondellBasell Microthene^® F products are ultrafine, spherically shaped polyolefin powders with an average particle size of 20 microns. Their uniform shape and narrow particle size distribution make Microthene^® F an effective thixotropic for lubricants. Microthene^® F powders improve the smoothness properties of a surface and can restrict the shrinkage of a finished part. Plastics used in applications such as automotive, appliance, electrical, and carbon water filters benefit from the properties of the microfine particle size. Grades are available in low-density polyethylene (LDPE), high-density polyethylene (HDPE), and ethylene vinyl acetate (EVA). 

Microthene^® F improves the gloss in plastics, specifically in molding applications. When utilized as a low-profile additive (LPA), processability improves, and the finished product may not require mold release agents. In addition to its low-profile additive benefits, Microthene^® F can work as a binder in filters and batteries, an anti-tack agent for tacky polymers, a viscosity modifier for grease, and a sintering agent in ceramics. 

• Excellent thixotropic properties
• Microfine powder form disperses easily and aids in the suspension of other additives within lubricants and greases
• Composed of a single polyolefin resin with a single melting point, whereas the competition is a low–molecular weight wax blend with multiple melting points
• Improved thermal stability and longer service life
• Broad FDA food contact approval
• Microthene^® F powder is easily colored and absorbs pigments
