Parker Chomerics PREMIER™ A230-FRHF EMI Shielding Plastic
Categories: Polymer; Thermoplastic; ABS Polymer; Polycarbonate/ABS Alloy, Carbon Fiber Filled; Polycarbonate (PC)

Material Notes: PREMIER™ is a versatile conductive thermoplastic for real world EMI shielding solutions. It is a blend of PC/ABS thermoplastic polymer alloys and conductive fillers engineered for stable electrical, mechanical, and physical performance. The conductive filler technology utilizes nickel plated carbon (Ni-C) fibers as the base filler. In the case of higher shielding versions, Nickel-Graphite (Ni-C) powder is blended with the fiber base to deliver enhanced performance. Combined with standard injection molding processes, PREMIER technology delivers evenly dispersed filler throughout a part’s geometry. PREMIER parts have no resin rich areas prone to EMI leaks, and no brittle, resin poor areas that can break under mechanical stress. PREMIER provides world class shielding effectiveness, requires no machining, plating, painting, vacuum coating, or other added processing steps. The elimination of secondary operations can reduce costs by up to 50% compared to die castings, bent formed metal, machined extrusions and plated.
