Better Dispersion and Longer Service Life with Microthene® F
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.
Why Choose LyondellBasell Microthene® F?
- 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
