Adhesive-free design enables removal for cable or accessory inspection Available in black or white Fire Retardant & Arc Proofing You can plan ahead for the best outcome in fire and arcing scenarios. Protect your low- and medium voltage cables and accessories with 3M’s arc proofing and fire retarding tapes. When the heat rises, the tape expands putting a thick layer of char between the flames and your cable to help minimize potential damage.
Jacket Repairing Shield your work from environmental wear and tear. When wrapped over a splice or damaged cable jacket, 3M jacket repairing tapes offer layered defense against external hazards. Vulcanized CSM rubber on the outside resists abrasion and chemical damage, while the inner layer includes flame-retardant mastic to keep moisture away and provide excellent adhesion to a variety of cable jacket materials.
Excellent abrasion resistance Bundling & Harnessing You never know what you’re going to find encounter on a project site. Be prepared to take on any challenge with 3M bundling and harnessing tapes that bind, hold and organize wires. Bundling tapes also offer excellent mechanical protection and can act like a second set of hands that steady wires in place.
