Syensqo (Solvay Specialty Polymers) Xydar® M-345 LCP, 45% mineral filled
Categories:	Polymer; Thermoplastic; Liquid Crystal Polymer (LCP); Liquid Crystal Polymer (LCP), Mineral Filled
Material Notes:	45% mineral filled, SMT processing Xydar® M-345 liquid crystal polymer (LCP) is a 45% mineral reinforced injection molding grade developed for electrical/electronic applications utilizing surface mount technology. The material can fill very thin walls over long flow lengths. In addition to low warpage, it exhibits good strength and stiffness (even at elevated temperatures), low coefficient of thermal expansion, high heat deflection temperature, inherent flame resistance and good chemical and weathering resistance. - Natural: M-345 NT - Black: M-345 BK Features: Chemical Resistant; Flame Retardant; Good Moldability; Good Stiffness; Good Strength; Good Weather Resistance; Low Warpage Information provided by Solvay Specialty Polymers.
