Nashua 354 Premium Duct Tape [Discontinued]
Nashua 354 is no longer being stocked. Please see Polyken 231, Nashua 357 or Shurtape PC-657 for an alternative thicker premium duct tape.
Nashua 354 Premium Duct Tape is premium-grade polyethylene (PE) coated cloth tape with rubber-based adhesive. Its clean release resists delamination and it tears straight, hangs straight and is curl resistant. Also has outstanding performance over a wide range of temperatures and conforms to a variety of surfaces. Nashua/Polyken 354 is used for heating, air conditioning, ventilating and refrigeration applications. Also for sealing of seams and joints in metal air handling systems and the manufacture of flexible duct equipped with metal collars. Other application used include bonding, protecting, holding, repairing, patching, asbestos removal, polyethylene hanging, sand and media blasting, waterproof packaging and heavy-duty repair and maintenance. Low VOC Content and can contribute toward satisfying EQ Credit 4.1 (Low Emitting Materials) under LEED®. Please note the current lot of rolls come on Polyken-branded core (both Nashua and Polyken are sub-brands of Berry Plastics).

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).
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
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
