A material with greater anisotropy tends to exhibit more warpage. A greater difference in mold shrinkage in the machine direction versus the transverse direction tends to indicate greater anisotropy in the material. In an LCP resin, there is already anisotropy in the polymer itself. (This feature represents the greatest difference between LCP and other engineering plastics.) Therefore, the anisotropy in an LCP resin is greatest when the LCP is non-reinforced (no filling material). Adding such filling materials as glass fibers (GF) disrupts the polymer orientation and relaxes anisotropy. Moreover, a filling material with low anisotropy is preferable to that with high anisotropy. That is to say, granular or tabular filler with low anisotropy is preferred over a fiber-like filling material such as GF.Molded product: Notebook PC memory socketNon-reinforced
