Abstract: Provided herein are polyamide compositions including one or more semi-crystalline polyamides and either an amorphous polyamide or a semi-crystalline copolyamide such as PA66/6. The provided compositions are particularly useful as vibration isolators more effective at high-temperature noise and harshness damping than conventional polyamide compositions. Also provided are methods for making the provided compositions, and articles that include the provided compositions.

Abstract: An impact-modified polyamide composition comprising from 5 wt % to 85 wt % of polyamide polymer; from 10 wt % to 60 wt % glass fiber; from 3 wt % to 30 wt % of an impact modifier; and a melt stabilizer at a concentration less than 5 wt %; wherein the weight ratio of the impact modifier to the melt stabilizer ranges from 1.0:1 to 100:1; and wherein the polyamide composition demonstrates an un-notched Charpy impact energy loss at 23° C. that is greater than 80 kJ/m2 and a tensile strength greater than 135 MPa.
