Product Description

Pres-On 1/2 inch thick Gasketing Foam Tape is an ultra-soft, open-cell polyester polyurethane foam tape engineered for reliable gasketing and sealing. Its fine, reticulated cell structure stays highly flexible and breathable, so it conforms to irregular surfaces and seals out moisture, dust, and drafts while dampening sound and vibration.

A single side is coated with Pres-On's superior direct wet-coat, high-tack rubber pressure-sensitive adhesive and protected by an easy-to-use release liner. The adhesive delivers a strong, lasting bond on a wide range of surfaces, and the foam resists aging, weather, and environmental damage over years of demanding use.

Key Features

  • Ultra-soft, fine-cell open-cell foam that compresses easily for a tight, conforming seal
  • High-tack rubber adhesive with excellent grab on a wide range of surfaces
  • Resists water, moisture, aging, and weather
  • Breathable with very good air permeability
  • Charcoal gray foam, available in multiple thicknesses and widths
  • The foam can be die-cut into custom shapes to fit your application.

Typical Applications

  • RV and automotive door gasketing
  • Filter gaskets
  • HVAC sealing
  • Enclosure and electronics gaskets
  • Cushioning
  • Insulation
  • Shock absorption
  • Vibration control
  • Gap filling
Country of Origin: United States.

Application Instructions

  1. Measure the area to be sealed and cut the foam tape to length with scissors or a sharp blade.
  2. Thoroughly clean the contact surface so it is free of dirt, oil, and moisture, then let it dry.
  3. For best adhesion, make sure the surface and tape are between 50°F and 80°F.
  4. Peel back a short section of the release liner at one end.
  5. Position the tape carefully and press it into place, removing the liner as you go.
  6. Apply firm, even pressure along the full length so the adhesive makes full contact with all surfaces.
  7. Once applied, the tape cannot be removed and reused, so discard any misaligned piece and reapply with a fresh length.

Nominal Tape Widths vs Actual Widths

Nominal vs. Actual Widths Zoom In

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 5% narrower than the NOMINAL width shown in inches. Examples:

  • 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.

QUESTION: Is the release liner pulled away from the adhesive side or non-adhesive side? for example on the product "JVCC SCF-01" the descriptions reads as follows: "The adhesive on this single-sided foam product is on the exposed side of the tape when you unwind it from the roll; the release liner is pulled away from the non-adhesive side of the tape"
ANSWER: For Pres-On P8500 series rolls the release liner is peeled away from the adhesive side of the rolls. Thank you.

User Reviews

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.
acrylic
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.
silicone
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).
