Abstract
A low dielectric material made of a liquid crystal polymer, polytetrafluoroethylene, and hollow glass spheres. This material is a relatively low cost, low dielectric blend having good physical strength and chemical and temperature resistance.
Claims20
A low dielectric material comprising at least about 30% by weight of a liquid crystal polymer, at least about 10% by weight polytetrafluoroethylene, and at least about 5% by weight hollow glass spheres, wherein said material has dielectric constant in the approximate range of from 1.1 to 3.4.
A low dielectric material comprising:
- from about 30 to about 60 percent by weight of a liquid crystal polymer which comprises repeating units derived from 4-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid;
- from about 10 to about 50 percent by weight of polytetrafluoroethylene;
- and,
- from about 5 to about 40 percent by weight of hollow glass spheres.
