NOISE DAMPING COMPOSITIONS

摘要

Disclosed are thermoplastic compositions having excellent vibration damping and noise suppression properties and molded articles made therefrom that can be manufactured inexpensively. The noise damping compositions of the present invention being (a) about 50-85 weight % of a polyamide; (b) about 5-45 weight % of a fibrous reinforcing agent; (c) about 1-25 weight % of zinc oxide; and (d) about 0-15 weight % of other additive; wherein the weight % is based on the total weight of the noise damping composition, and provided that the composition has essentially no flame retardants.
