Nashua 360-17 FoilMastic Butyl Rubber Tape is a printed, 2 mil dead-soft aluminum foil backing with a 15 mil butyl rubber mastic adhesive. It is a waterproofing repair tape used for indoor or outdoor sealing of low, medium & high-pressure HVAC duct systems (includes: metal duct, fiberglass duct and flexible duct systems). It seals cracks and seams in gutters, roof alleys, eaves, hips and ridges and seals around chimneys and vent stacks. You can use Nashua 360-17 to repair gouges, rips, tears in metal panels of trailers, shipping containers and metal buildings. Also used to seal leaks in vans, cars, and trucks and for mobile home repair. Use duct mastic to mend poorly sealed connections, improve indoor air quality (since fewer pollutants circulating), lower utility bills, and burn fewer fossil fuels. SMACNA A, B, and C Seal Classes. UL 723 classified. Low VOC content and can contribute toward satisfying EQ Credit 4.1 (Low Emitting Materials) under LEED®.
Please note that Nashua 360-17 and Polyken 360-17 are the same product manufactured by Berry Plastics. Therefore the tape roll core may be branded with Nashua or Polyken, depending on current inventory.

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).

Nominal Tape Widths vs Actual Widths
5% narrower than the NOMINAL width shown in inches. Examples:
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
- 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.
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).
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 based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
