Described herein are polyamide foam particles including a polymer mixture including: (A) from 25 to 95 wt.-% of at least one polyamide, which is different from a copolyamide (B); and (B) from 5 to 75 wt.-% of at least one copolyamide prepared by polymerizing the following components: (B1) from 15 to 84 wt.-% of at least one lactam; and (B2) from 16 to 85 wt.-% of monomer mixture (M) including; (M1) at least one C-Cdimer acid; and (M2) at least one C-Cdiamine; where the sum of the components (B1) and (B2) are 100 wt.-%. Also described herein is a process for preparing such polyamide foam particles and polyamide particle foam moldings obtainable by steam-chest molding.

High crystallinity polyamide foam particles and foam moldings

Expandable, blowing agent-containing pellets based on high temperature thermoplastics having a glass transition temperature according to ISO 11357-2-1999 of at least 180&#xb0; C., wherein the expandable, blowing agent-containing pellets comprise at least one nucleating agent and have a poured density according to DIN ISO 697:1982 in the range from 400 to 900 kg/mand a mass in the range from 1 to 5 mg/pellet, processes for production thereof and foam particles obtainable therefrom having a glass transition temperature according to ISO 11357-2-1999 of at least 180&#xb0; C., wherein the expanded foam particles comprise at least one nucleating agent and have a poured density according to DIN ISO 697:1982 in the range from 10 to 200 kg/m, and particle foams obtainable therefrom and the use thereof for producing components for aviation.
