20250215220 · 2025-07-03 ·

Compositions include from about 50 wt % to about 85 wt % of a liquid crystal polymer resin, from about 0.1 wt % to about 15 wt % of a polyetherimide polymer, from about 0.05 wt % to about 8 wt % of a compatibilizer, and from about 2 wt % to about 25 wt % of a mineral filler. A 50 mm60 mm sample having a thickness of 0.6 mm molded from the composition exhibits an anti-dent performance characterized by a dent depth from 30-40 micrometers as measured using a three dimensional surface profiler; the sample is tested using a drop tester with a 1.6 mm diameter steel ball having a weight of 50 grams dropped from a height of 50 mm. Articles including the composition, including components of a mobile compact camera module, are also described.
