3M 5151 / 5151PL General Purpose PTFE Glass Cloth Tape [Silicone Adhesive]

3M 5151 / 5151PL General Purpose PTFE Glass Cloth Tape [Silicone Adhesive]

Product Description

3M 5151 and 515PL General Purpose PTFE Glass Cloth Tape are constructed using polytetrafluoroethylene (PTFE) impregnated glass cloth with silicone adhesive. These tapes are used in many applications requiring high-temperature performance and high abrasion resistance. 3M 5151 is linerless and 5151PL comes on an embossed UPVC random dot pattern liner.

Uses & Applications

  • Easy release surface on packaging and heat sealing machines, ironing and pressing equipment.
  • Release surface on metal bonding tools.
  • Lining conveying chutes, troughs and ducts.
  • Covering rollers, drums, turnbars and formers on stitches, binders and other process machinery.

Features & Benefits

  • Very low moisture absorption allows the tape to perform in many humid environments.
  • Provides greater tensile strength and resistance to tear and puncture than typical PTFE film backed tapes.
  • Thick glass cloth backing for a long wear life and high impact and puncture resistance.
  • Silicone adhesive offers high temperature performance and long aging.
  • Thick PTFE coating for an exceptionally smooth surface and provides non-stick, low friction surface.
Made in the U.S.
* Multiple cases may be shipped per package in order to minimize the charge for shipping.

Alert Roll 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).

Question & Answers

3M 5151 / 5151PL General Purpose PTFE Glass Cloth Tape [Silicone Adhesive]
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
