Polyken 747 Marine Boat Wrap Heat Shrink Tape is used for taping off shrink wrap material, seaming pieces of shrink film, and minor repairs and maintenance primarily in the boat wrap industry. In addition, Polyken 747 can be used as a dissimilar metal barrier and as a short-term masking product for stucco and plaster applications. This tape is also described as poly patching tape and intended to be used to join seams of shrink wrap material together in larger applications, such as a boat or large machine.
Polyken 747 is typically applied to a heat shrink film product, but the heating torch should not be directed at the tape which may cause it to melt. Because the tape is in the vicinity of the heat, it is expected to crinkle a little bit to maintain it's hold on the film. The shrink film has enough additives that the heat will not completely melt the tape.
The polyethylene (PE) film backing of Polyken 747 Heat Shrink tape makes this tape conformable and flexible, has excellent durability and solvent resistance and provides low elongation for a consistent surface bond. Polyken 747 has a synthetic rubber adhesive which ensures high tack for a quick stick, excellent shear strength, and is easily repositioned and removable from many surfaces. Polyken 747 is environmentally friendly and safe to use. This tape contains low volatile organic compounds (VOC) and contains no heavy metals, such as lead and chromium. The tape is offered in blue, clear and white colors; and the blue and white colors are not completely opaque (can see sunlight through tape, but would not be able to read writing).

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.
