POLYOLEFIN MICROSPHERES N e w forms of polyethylene result in further applications A series of polyolefin powders, called Microthene F microfine polyolefins, has been introduced by U. S. Industrial Chemicals Co. The new series is believed to be produced by chemical means to give a smaller particle size than is possible by conventional grinding. T h e particles produced are microspheres, 8 to 30 microns in diameter, and are expected to provide nearly homogeneous dispersions in various solvents. T h e physical properties of the microspheres are identical with those of the polyolefins from which they are manufactured. Available in commercial quantities are Microtherre FN 500 with a melt index of 22 and a specific gravity of 0.915, and Microthene FN 510 with a melt index of 5 and a specific gravity of 0.924. T h e company expects to extend the series to include linear polyethylene, polypropylene, and the ethylene-vinyl acetate copolymers introduced earlier this year. Applications. The microspheres
can be dispersed in water or organic liquids in concentrations as high as 50% solids. These dispersions, said to be stable for several hours, can be pumped, brushed, sprayed, or roll coated on many surfaces. An important application for these powders is paper coating. Water dispersions, made with a number of different surfactants, can be applied cold to paper and other substances with conventional wetcoating equipment when heated to temperatures of 300° to 350” F., and at commercial surface speeds. T h e result is a continuous coating with properties comparable to those obtained by extrusion coating. If an organic system is preferred, solvents other than water may be used. T h e only requirement is that the density of the solvent be about the same as that for the microspheres to minimize settling. T h e use of these dispersion coatings is said to allow for shorter coating runs than those economically possible with extrusion coating.
Another advantage is that edge trimming is not required, since coating application can be stopped short of the paper’s edge to allow for a glued strip. T h e new materials are also expected to invade the woven and nonwoven fabric markets. Dispersions of the new materials, which can be knife-coated, are expected to compete with mechanically ground materials in the areas of carpets, fabric backings, and interliners. Careful formulation of these dispersions is expected to result in a binder which rests at the fiber crossovers resulting in a material with a good “hand.” Compatibility with epoxies and polyesters permits their inclusion in the basic resin to provide moldings with improved surface finishes and surface integrity, and better flexibility. T h e powders are also expected to provide a number of other applications such as additions to paints, varnishes, and lubricants. 20 1

QUALITY- MADE is meaningful when describing any product bearing the Hackney trademark, famous in industry for more than 61 years. For example, the deep drawing of alloy steels to uniform close tolerances in forming rugged, safe, high-pressure cylinders. Every Hackney cylinder shell is made by this technique-deep drawn to final size and shape between precision dies and mandrels. The results: smooth, strong cylinders without excess weight, which are easy to maintain; less costly to ship; easier to handle. Quality is a goal for our engineers, regardless of the Hackney products to be made.

Accurate extrapolation of lab results is now possible with the new 20-inch Sturtevant Air Separator. No longer does our industry have to use small production units for pilot and lab work. The 20-inch Sturtevant Air Separator will classify from ounces to hundreds of pounds a n hour, depending upon feed, feed r a t e and required particle size. True lab work - a t Sturtevant or at your own plant - is now a reality. The2O-inch unit fills out Sturtevant's comprehensive line of a i r separators. Besides the lab unit, a three-foot model f o r pilot and moderate production is available. Larger-scale s e p a r a t o r s range from six t o twenty feet in diameter and classify in tonnage quantities. All a r e available with fully external adjustment devices which allow shiftover from coarse to fine selection in minutes, without shutdown of the sepamtorl Write for Bulletin 087. O r let us know about your plant problems.
