Abstract
Polyamide compositions and articles shaped therefrom have good dimensional stability and contain at least one novolac resin and nanometric flake structure filler material; the articles shaped therefrom, e.g., by injection molding, are useful in a various of applications, for example as engineering plastics.
Claims20
A polyamide composition consisting of:
- at least one polyamide;
- at least one novolac resin;
- a filler material having nanoscale sheet structures;
- reinforcing or bulking fillers;
- and
- additives selected from the group consisting of lubricants, plasticizers, nucleating agents, catalysts, resilience improvers, light stabilizers, heat stabilizers, antioxidants, antistatic agents, dyes, pigments, matting agents, and molding agents;
- wherein the novolac resin is present in the composition in an amount of from 1% to 25% by weight relative to the total weight of the composition.
