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.
