Saint-Gobain® CHR® C665 Copper Foil Tape
CHR® C665 Copper Foil Tape features an electrically deposited copper foil backing paired with a conductive acrylic adhesive. This construction is designed to deliver electrical conductivity through the entire tape structure, supporting EMI/RFI shielding and grounding performance in electrically demanding environments.
Applications include: A diverse range of markets including electronics, electrical, transportation, aerospace, and general industrial, where full-construction conductivity is required for shielding, grounding, and static dissipation in IC chips, electrical cabinets, cables, and motors.
- Conductive copper foil backing and conductive acrylic adhesive enable electrical continuity through the entire tape construction
- Engineered to support EMI/RFI shielding and grounding applications where conductivity across the bond line is required
- Conformable foil construction allows the tape to adapt to complex or irregular surfaces
- Supplied with a release liner to support precision die cutting and custom converting
- Provides effective sealing against radiated and leaked electromagnetic interference
- Solvent resistance to maintain performance in demanding operating environments
- Recognized under the UL component program, Guide OANZ2, File E51201
- Meets UL510 flame-retardant requirements
