Copper Foil with Acrylic Adhesive (38836A) and Conductive Acrylic Adhesive (38837CA) Special electrograde, zero temper, high tensile copper foil tape. Provides excellent solderability. Malleable copper foil conforms well to irregular contours. Its aggressive acrylic adhesive system creates a superior bond. Used for RFI/EMI shielding applications in the electrical/electronics industry. Annealed and non-tarnishing. Meets UL 510 specifications. CFL-5CA is coated with an acrylic adhesive which is uniformly dispersed with conductive spheres to provide a very low rate of electrical resistance through the tape. Electrical resistance: 0.003 Ohms/in2 . 3” plastic core.
Typical Applications for Copper Foil
Copper Foil with Acrylic Adhesive (38836A) - EMI/RFI shielding of small electromagnetic components (i.e. transformer/reactor coils) and cable splices; repairing, modifying & prototype designing wiring boards, supplementary shielding of joints/seams; flat conductor assemblies.
Copper Foil with Conductive Acrylic Adhesive (38837CA) - Cable wrapping to provide EMI/RFI shielding, seaming of EMI/RFI shielded rooms for electrical continuity, static charge draining, surface contact to non-solderable materials (e.g. aluminum or plastics).
