Material Notes:
XYDAR MG-350 Liquid Crystal Polymer (LCP) is a mineral and glass-filled injection molding grade developed specifically for cost-effective performance in applications where a balance of flatness and strength are required. The moldability of this resin is exceptional. XYDAR MG-350 resin can fill very thin walls over long flow lengths with little or no flash, even at mold temperatures below 200°F (93°C). In addition, it has low warpage in molded products and good weld line strength. Like other XYDAR Liquid Crystal Polymers, this material temperatures), low coefficient of thermal expansion, high deflection temperature, inherent flame resistance, and outstanding resistance to most chemicals, weathering, and radiation.This resin is particularly well suited for many applications that have difficult-to-fill geometries, and require resistance to warp and strong weld lines. Potential applications for this resin include electronic connectors, burn-in sockets, automotive components, chemical processing and other mechanical devices.Information provided by Solvay Advanced Polymers. This grade was discontinued in 2006.
