Product Description

Presco Underground Non-Detectable Warning Tape is a 4 mil thick, NON-ADHESIVE, polyethylene (PE) film tape used to help prevent damage to underground utility lines during excavation. Presco Non-Detectable tape is resistant to underground elements, heavy metal-free, and will not turn black over time. Available in 3-inch and 6-inch wide x 1000 foot rolls, this bright warning tape alerts anyone to the presence of lines and cables below ground.

Presco Underground Non-Detectable Warning Tape can be used in construction, turf and irrigation, CATV, utilities, and by pipeline and mechanical contractors. Following code parameters, you can bury this tape above electrical lines, gas pipes, communication cables, and other utility installations. Presco Non-Detectable Warning tape is buried 4 in. to 6 in. below the surface so that it is dug up prior to reaching a depth that could cause damage to the line or person(s) digging.

Please note that Presco Underground Non-Detectable Warning Tape can be shipped on a non-branded neutral core or a Presco branded core.

Very reasonably priced.

This was a great value, shipping was equal to price unfortunately.
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).
