SUMIKASUPER® E4205R

Generic Family: Liquid Crystal Polymer • Supplied by: Sumitomo Chemical Co., Ltd.
SUMIKASUPER E4205R is a Liquid Crystal Polymer (LCP) product filled with glass fiber/inorganic. It is available in Asia Pacific, Europe, Latin America, or North America for injection molding.

E4000 series are distinguished by their very-high heat resistance and retention of stiffness and strength at temperature above 200°C, meaning they can be used for high-temperature surface-mount reflow soldering. E4000 Series grades are typically processed at 380°C.

E4205R is a 25% glass fiber/inorganic filler grade with high heat resistance, low thermal conductivity, low relative permittivity, and thermal insulation. E4205R is used for injection molded various connectors as well as parts for office equipment such as printer components.
