Nashua 322 General Purpose Foil Tape [2 mil Linered]

Nashua 322 General Purpose Foil Tape [2 mil Linered]

Product Description

Nashua 322 General Purpose Foil Tape has a 2 mil thick aluminum foil backing and is specially designed for taping joints and seams against moisture and vapor on foil jacketing insulation. Appropriate for a variety of insulation uses. Also used in the automotive industry for general repair. The tape has excellent conformability to curved surfaces like corners and joints and has excellent quick stick adhesion (very high tack). Nashua 322 also has UV and moisture resistant and is mold and mildew resistant. Non-solvent for less odor and low VOC content and good all-weather performance.

Our converter received in a few cases of this tape in in this shorter 40 yard length (instead of 50 yard) and have marked it down temporarily to this sale pricing.

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).

Nashua 322 General Purpose Foil Tape [2 mil Linered]
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
