3M 7000031674 – Frequently Asked Questions
1) Can Scotch 35 gray vinyl tape be used as primary insulation on 600V circuits?
Yes. Scotch 35 is rated 600 V and carries a dielectric strength of 1250 V/mil over a 7 mil (0.18 mm) total thickness, so it works as primary insulation on low voltage work as well as for color coding. It is not intended for high voltage splices, where you would move to a self-fusing rubber splicing tape with a vinyl overwrap.
2) Will this tape hold up outdoors or in an unheated building?
Its working range runs from 14 to 221 degrees F (-10 to 105 degrees C), and the PVC backing is UV resistant plus resistant to moisture, abrasion, alkalis, solvents and many acids. That covers exterior conduit runs, rooftop equipment, and cold warehouses. Below 14 degrees F the vinyl gets stiff and application suffers, so stretch and conform it at room temperature where you can.
3) Is Scotch 35 flame retardant for use inside panels and cable trays?
Yes, it's flame retardant and self-extinguishing, which is why it gets specified for taping inside enclosures and on tray cable. It is UL Listed under file E129200, CSA Certified, VDE licensed, and meets IEC 60454-3-1-6/F-PVC P/90.
4) What does the gray color signify when phase-taping conductors?
Gray is used in phase identification and color coding of motor leads, piping systems, and safety area marking. In US practice gray commonly marks the grounded neutral of a 277/480V system, but the color convention you follow is set by your facility standard or local code, not by the tape. The tape itself is the same Scotch 35 PVC construction in every color, so a full color set behaves identically on the conductor.
5) What's the difference between Scotch 35 and a general-purpose vinyl electrical tape?
Scotch 35 is the premium-grade 7 mil vinyl, thicker than the common 33+ style general-purpose tape and offered in a full color range so it doubles as a coding tape. The construction is a rubber-resin pressure-sensitive adhesive on a PVC backing, with 20 oz/in adhesion to steel and 225 percent elongation, so it stretches and conforms around irregular terminations without lifting.
6) Does this tape fuse to itself like a splicing tape?
No. Scotch 35 is a non-vulcanizing pressure-sensitive vinyl, so the layers do not fuse into a single mass. For a moisture-tight high voltage splice you want a self-fusing rubber splicing tape as the body of the splice, with this vinyl applied over it as the jacket and abrasion layer.
7) How long can I keep rolls of this tape on the shelf before using them?
Shelf life is five years. Store the rolls in their original packaging out of direct sun and away from heat so the rubber-resin adhesive does not dry out or ooze at the roll edges.
8) Will this tape tear off cleanly by hand or does it stretch and thin out?
It breaks at 30 N/10 mm tensile with 225 percent elongation, which is the balance electricians expect from premium vinyl: enough stretch to conform tightly around a wire nut or lug, and a clean hand tear at the end of the wrap without needing a knife.
9) Does 3M Scotch 35 meet RoHS for a European or spec-driven project?
It is RoHS compliant without exemption under 2011/65/EU, and the product literature also cites RoHS 2015/863/EU compliance. It additionally carries a VDE Marks License, which is what usually gets asked for on European-specified panels.
