3M 35-ORANGE-3/4X66FT 35 Orange 3/4" x 66' Vinyl Color Coding Tape

Scotch 35 is a premium-grade PVC electrical tape, so it insulates as well as identifies. The backing is polyvinyl chloride with a rubber resin adhesive, dielectric strength is 1250 V/mil at 7 mil thick, and it's rated for low voltage applications. That makes it usable for phase marking on conductors you are also splicing or jacketing, not just a marking stripe.

Not for sustained sun exposure. Scotch 35 is not UV resistant, so outdoor runs in direct sunlight will fade and degrade the vinyl over time. It's fine in outdoor locations that are shaded or enclosed, in conduit bodies, panels, pull boxes, and wet interior environments. For exposed rooftop identification, plan on re-marking or protecting the tape.

Operating range is 0 to 105 degrees C (32 to 220 degrees F). The 105 C top end is the standard building wire insulation rating, so it keeps up with THHN in a hot panel or motor connection box. At the low end, applying near freezing is where vinyl gets stiff and adhesion suffers, so warm the roll before taping in a cold mechanical room or unheated garage.

Orange is the B phase in the common 277/480V convention of brown, orange, yellow. On 120/208V systems the usual set is black, red, blue, and orange is instead reserved for the high leg of a 120/240V delta. Scotch 35 orange is sold specifically for phase identification and color coding of leads, so it suits either use, but confirm which convention your facility or the AHJ has standardized on before you mark a panel.

Scotch 35 is UL Listed and CSA Certified, and also meets VDE 0340-TEIL1. That covers the typical North American inspection requirement for tape used as electrical insulation rather than plain marking film.

Yes. Beyond phase identification, Scotch 35 is intended for color coding piping systems and marking safety areas. The PVC backing and rubber resin adhesive hold on metal pipe, conduit, and painted surfaces, and facilities buyers commonly standardize on the 35 line across trades so one color scheme covers electrical, mechanical, and floor marking. Keep it out of continuous sunlight, since the tape isn't UV resistant.

Yes, Scotch 35 is RoHS 2011/65/EU compliant without exemption. That matters on government, healthcare, and institutional submittals where every consumable on the bill of materials has to clear the same environmental spec.

Scotch 35 is 7 mil thick, which is heavier than the standard 7 mil general purpose black vinyl tapes are often compared against and noticeably more substantial than economy 5 to 6 mil tapes. It's graded premium, with a PVC backing and rubber resin adhesive, so it behaves like a full insulating tape rather than a thin marking film. If you are only banding conductors for identification, the extra body is what keeps the band from unraveling in a crowded gutter.
