Product Description

Duck Brand Self-Fusing Rubber Splicing Tape is used to protect your electrical project from the elements. Instantly create watertight barriers around low voltage electrical splices or wire repairs with Duck® Brand Rubber Splicing Tape. How does this electrical tape create such a durable seal? Its design allows super conformability and stretch so it easily wraps around even the trickiest wires. Plus, its easy-tear and removable liner takes the frustration out of the job - no need for tools to cut it, just use your hands to tear the tape, even with the liner. Duck Self-Fusing Rubber Splicing Tape is designed for use in splicing and terminating wires and cables. The tape is self-fusing which means it is an adhesive-free tape that fuses only to itself (no sticky residue left on surfaces) so there won't be a noticeable tackiness to the tape. Also, be sure to remove the blue liner before applying the tape and the tape sticks best by being slightly stretched as you wrap it around the wires, not too much but just to give a little tension. Country of Origin: United States.

QUESTION: Is this for use with 120v? I need to cover the free end of a gutter heater cable (temp less than 120F) located in a downspout. I plan to place a waterproof silicon filled wire nut over the end and then wrap the nut with this tape.
ANSWER: This tape from Duck is UL-listed so can handle temperatures up to 176F; however, this is a self-fusing tape so really doesn't offer any adhesion or tackiness on its own - the tape, when wrapped around wires, fuses onto its own backing so not sure how would work for covering a nut although the tape is pretty conformable. Thank you.

Duck Brand Self-Fusing Self-Fusing Rubber Splicing Tape
Unlike regular electrical tape that slides off with time, this stuff fuses to itself and stays put'
Made in the USA
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.
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
The cut level indicates how many grams of cutting load a glove can withstand from a sharp blade before being penetrated.
Lower gauge gloves are heavier - have thicker construction, fewer stiches knitted per inch and offer less dexterity.
Higher gauge gloves are lighter - have thinner/finer construction, more stitches knitted per inch and offer more dexterity.
Gloves offered typically runs from 7 to 18 (12 and 13 are in the middle of the scale).
