    • Thermosetting and thermoplastic elastomers are provided having magnetic filler packed within the elastomeric matrix and capable of being aligned and energized, before, during or after the molding of the elastomer. The magnetically-filled elastomers therefore provide useful permanent magnetic fields which being physically soft. The magnetic filler is aligned within the elastomeric matrix and energized by subjecting the magnetically-filled elastomer to magnetic energy before, during and/or after molding of the magnetically-filled elastomer. A particularly preferred magnetically-filled elastomer is a magnetically-filled polyurethane elastomer composition wherein the elastomer is the reaction product of a urethane-forming compound having at least two urethane-forming reactive sites, an elasticizing diol or triol, and a diisocyanate reacted in less than stoiciometric amounts to allow for the formation of urethane linkages involving less than about 85% of the urethane-forming reactive sites. Vibration dampening devices employing elastomers and, more particularly, the magnetically-filled elastomers of the present invention are also provided.
    • 提供热固性和热塑性弹性体,其具有填充在弹性体基体内的磁性填料,并且能够在弹性体模制之前,期间或之后对准和通电。 因此,磁性填充的弹性体提供了物理上柔软的有用的永久磁场。 磁性填料在弹性体基质内对齐,并通过使磁性填充的弹性体在磁性填充的弹性体的模制之前,期间和/或之后经受磁能来激励。 特别优选的填充有磁性的弹性体是填充有磁性的聚氨酯弹性体组合物,其中弹性体是具有至少两个氨基甲酸酯形成反应性位点的氨基甲酸酯形成化合物,弹性化二醇或三元醇和二异氰酸酯反应的反应产物 比经统计量允许形成涉及小于约85%的氨基甲酸酯形成反应位点的氨基甲酸酯键。 还提供了使用弹性体的振动阻尼装置,更具体地说,本发明的磁性填充弹性体。
