Polypropylene film laminated aluminum foil
High purity aluminum foil offers excellent electrical conductivity, easy etching and effective EMI shielding. Aluminum foil is versatile, easy to form, and resistant to heat and corrosion. Polypropylene (PP) offers high impact resistance, mechanical strength, and resistance to a wide range of solvents, acids and bases.
Shielding laminates consist of at least two materials whose combined performance exceeds that of their individual components. In our context, we refer to shielding laminates consisting of both metals and non-metals, usually involving a combination of PET, PP, PI, PPS, PTFE with metals such as copper and aluminum.
Metal shielding laminates are produced by continuously bonding two thin metal sheets or natural metal films to one side of a thermoplastic core. These cores form sheets that are lighter in weight, easy to fabricate, flat and durable.
EMI solutions include three main approaches: electromagnetic interference shielding, printed circuit board grounding, and electromagnetic interference absorption.
