New additives for grease capable of economically enhancing performance were studied. Nine commercially available polymer additives were selected to investigate the performance of a variety of polymer chemistries in grease including novel proprietary polymers. Polymer additives showed their usefulness in grease formulations in a variety of ways at modest treatment levels. When added to grease, polymer additives can increase shear stability resulting in longer grease functionality. These additives can enhance the water resistance of grease in applications where water contact is present. When in liquid and gel form, the polymer additives have the potential to reduce finishing time for grease formulations compared with powder and pellet forms.

A selection of polymers with different structures has been incorporated into mineral oil-based grease and soybean-based grease. Semi-crystalline ethylene/propylene copolymer (OCP) and styrene-ethylene-butylene copolymer can significantly improve the water resistance of mineral oil-based grease, but they do not work for soybean-based grease. Polyisoprene (PIP), styrene-butadiene copolymer, and amide grafting OCP work well in improving the water resistance of soybean-based grease. By adding 1% of a high molecular weight PIP in a vegetable oil-based grease, the weight loss percentage of the grease in water spray test decreases from 83% to 17%. By adding 1% of an OCP in a mineral oil-based grease, the weight loss percentage decreases from 73% to 15%. The improvement of the water resistance performance after adding polymer is due to the forming of interpenetrating networks by polymer and soap thickener together. All the polymers show positive results in improving the shear stability of grease.

An alumina fiber aggregate which is minimized in scatter of fibers, excels in handling characteristics and working environmental hygiene and finds its useful application to support mats for catalytic converters and such is provided. An alumina fiber aggregate comprising alumina short fibers having such properties that when diameters of said alumina short fibers are represented by x (m), the rate at which the natural logarithmic value ln x in lognormal distribution of x is less than ln 3 is not more than 2%, and the value left after deducting from the length-weighted geometric mean of said fiber diameters a value twice its standard error is not more than 6 m; and a support mat for catalytic converters comprising such an alumina fiber aggregate.


The effect of adding polymers with different structures to lithium grease (mineral oil-based and vegetable oil-based) was studied. The addition of polymer into grease significantly improved its performance, especially water resistance and shear stability. By adding 1% of a high molecular weight polyisoprene in a vegetable oil-based grease, the weight loss percentage of the grease in water spray test decreased from 83 to 17%. The addition of 1% ethylene/propylene copolymer in a mineral oil-based grease decreased the weight loss percentage from 73 to 15%. Due to the chemistry difference between mineral oils and vegetable oils, the compatibility of polymer with base fluid varied from the chemical structure. Thus, some polymers working for mineral oil-based grease do not work well in vegetable-based grease.
