Abstract
Described herein are polymer compositions including at least 20 wt. % of a liquid crystal polymer (“LCP”); 10 wt. % to 40 wt. % of a flat glass fiber and 15 wt. % to 50 wt. % of boron nitride and/or zinc oxide. It was surprisingly discovered that polymer compositions including an LCP in conjunction with a combination of flat glass fibers and boron nitride and/or zinc oxide had improved thermal conductivity and flexural properties, relative to analogous polymer compositions having round glass fibers in place of the flat glass fibers.
Claims15
A polymer composition comprising:
- at least 20 wt. % of a liquid crystal polymer (“LCP”) formed from the polycondensation of the following monomers:
- terephthalic acid, an aromatic diol, a first aromatic dicarboxylic acid, an aromatic hydrocarboxylic acid;
- 10 wt. % to 40 wt. % of a flat glass fiber;
- and
- Boron nitride and/or zinc oxide, wherein the total concentration of boron nitride and zinc oxide is 15 wt. % to 50 wt. %.
