Microthene® FN 519-00 is a 20-micron, low-density polyethylene powder with a melt index of 5. This grade is a flow-enhanced version of Microthene® FN 510.
LyondellBasell Microthene® FN 519-00 is a 20-micron, ultra-fine spherical polyethylene powder mostly used as an additive in a broad range of specialty applications. FN 519-00 is a flow-enhanced version of FN 510-00. It has small amounts of fumed silica to reduce bridging and clumping. Microthene® powders offer the properties of polyolefin resins but in microfine particle size, making them suitable for dispersion in aqueous systems and improving processability for thermoplastic manufacturing.
