Abstract: Described herein is a polyamide composition, which includes at least one polyamide, hollow glass bubbles, and impact modifier, where the impact modifier includes a combination of grafted impact modifier and non-grafted impact modifier. The polyamide composition has improved the mechanical properties of a molded body made from the composition, especially the toughness, and a balance in stiffness and toughness without sacrificing the weight-decreasing effects at the same time.

Abstract: Disclosed herein is a polyamide composition, comprising including from 30 wt % to 70 wt % of polyamide mixture and from 30 wt % to 70 wt % of filler mixture, and from 0 to 10 wt % of additives (E), based on the total weight of the polyamide composition. The polyamide composition provides advantage of good flatness and less dust particles, meanwhile the mechanical properties are maintained. Such advantage makes the polyamide composition especially suitable for the optical element application.
