Nominal Tape Widths vs Actual Widths

Nominal vs. Actual Widths Zoom In

Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:

  • 1" Nominal width = 15/16" (24mm) Actual width
  • 2" Nominal width = 1-7/8" (48mm) Actual width
  • 3" Nominal width = 2-13/16" (72mm) Actual width

Note that tape rolls are NOT guaranteed to be splice-free.

Product Description

3M 8979 Performance Plus Duct Tape is a performance-grade duct tape for indoor and outdoor use. It can removes cleanly with no residue from most opaque surfaces for up to six months after it is applied. It's strong waterproof backing resists wear, abrasion, moisture, and weathering for long-term performance and weatherability. 3m 8979 can be used for permanent or temporary applications.

Features & Benefits

  • Aggressive adhesive for quick and reliable attachment.
  • High tensile strength for demanding applications.
  • Easy to tear by hand straight across and down without curling for ease of application.
  • Tack-free roll edges to keep roll clean and minimize waste.
  • Writable surface for marking and identification.
  • Resistant to delamination and deterioration when exposed to UV outdoors for up to one year.

AlertRoll Sizes/Widths:

Please note that tape rolls are NOT guaranteed to be splice- free. Tape rolls are typically cut to standard tape industry metric-cut sizes - or approx 5% narrower than the nominal size (i.e. 24mm per 1-inch of nominal width ordered).

Please contact us to inquire about pricing for full-cut widths (e.g. a 6 inch roll cut to exactly 152mm instead of 144mm).

3M Scotch 8979 Performance Plus Duct Tape
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
