產品說明

Unitika Rodrun is a thermoplastics for percision injection classified into semi-aromatic liquid crystal polyesters (LCPs). LC-5000 series has a excellent moldability (high flow without flash, using a mold of low temperature) and precision (low warpage).

LC-5000 series are suitable for almost all dipping soldering conditions and partial reflow soldering (low warpage).

LCP has stiff molecular structure to form liquid crystal at molten stage. The archeological properties of low viscosity under shear stress gives high flow without flash problems. Rodrun which use a standard mold temperature of 40°C shows the rheological merit of LCP clearly.

Out shape of a LCP seem to be just like a normal plastics, however, the solid LCP consists of crystal and glasified liquid crystal. Rodrun has a low crystalinity in the mold. This property yields low shrinkage and low warpage. Rodrun is a suitable resin for precision parts.
