Microthene FN 519-00 is a 20 micron ultra-fine spherical polyethylene powder that is 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 a microfine particle size making it suitable for dispersion in aqueous systems.
Microfine particle size Uniform particle distribution Spherical shape Long shelf life Easy to disperse Flow enhanced version - reduces bridging and powder clumping
Problems Solved
Shrinkage and compatibility issues of PE powders in composites Lacking strength or insufficient binding in films and plastic applications Viscosity drops in greases and coatings formulations Difficulties reducing the sintering point in ceramics
Applications
Low shrink additive for composites Improve gloss in plastic molded parts Binder in filters and batteries Antitack (pellet dusting) in tacky polymers Viscosity modifier in grease, inks, coatings Carrier/Matrix for fabrics, paper Sintering agent in ceramics
