Will This Adhesive Tape Hold? Testing the Adhesive Strength of Double-Sided Tape.
You may not believe it, but double-sided adhesive tape has remarkable – even Herculean! – strength. Some pressure-sensitive tape is even used as a replacement for rivets in buildings or in manufacturing. In other words, it's not just for mounting frames and other wall hangings.
Double-sided tapes are available in different backing or carrier types such as film, tissue, cloth, paper and foam and they are available in a range of peel adhesions and tensile strengths. Our least adhesive double-sided film tape, the JVCC DC-4109RS product has a peel adhesion of 29 ounces per inch and is comparable to a general-purpose masking tape. It's perfect for mounting lightweight items, such as nameplates.
But that's just a start. Some of the other double-sided tapes we offer at FindTape.com have very impressive strength and adherence qualities. A double-sided film tape like Scapa S301 Double Coated UPVC Tape is adhesive enough to be used in product assembly, while 3M 4950 VHB Tape is used in both interior and exterior structural bonding applications.
But rather than tell you about the adhesive strength of our double-sided tapes, I'd like to show you. In this video, I test four double-sided tapes to see which one can support the most weight. Check it out.
Ludlow M-Tak HI/LO Extended Liner Tape is now being stocked in liner widths of 1/2 inch, 3/4 inch and 1 inch wide (the tape comes in lengths of both 216 feet and 1,300 feet per roll). The extended liner on the tape allows end users to easily remove it since there is a 1/8 inch overhang on both the top and bottom of the tape (the liner is also printed with the words "TO EXPOSE ADHESIVE REMOVE LINER"). Ludlow HI/LO is differentially coated which a clear, lightweight adhesive for temporary bonding and repositioning on one side, and a permanent adhesive for long-term bonding on the other side. Its perfect for lightweight attachments where removability from one surface is key, e.g. business forms, mailers, envelopes, posters, labels, etc.
Our converter has recently made available a new test pack that contains a variety of double-sided tapes. FindTape DC-TP Double-Sided Tape Test Pack consists of 12 rolls of 1-inch wide x 3-yard long tape. The carrier varieties included in the pack are: polyester, polypropylene and PVC film; tissue; crepe and flatback paper; polyethylene foam; cloth and scrim; and foamed and solid acrylic polymers.
Currently the specific double-sided tapes offered in the pack include: Polyken 105C-P Cloth Tape; JVCC DC-4199CS Polyester Film Tape; JVCC DC-1503 Polypropylene Film Tape; JVCC DC-4420LB Clear PVC Film Tape; JVCC DCP-01 and DCP-02 Crepe Paper Tape; JVCC DCP-04 Flatback Paper Tape; JVCC DCT-40R Tissue Tape; JVCC DC-SCRIM-9 Polyester Scrim Tape; JVCC DC-PEF06A Polyethylene Foam Tape; JVCC DC-UHB45FA-G Foamed Acrylic Tape; and JVCC DC-UHB45 Solid Acrylic Foam Tape.
3M 9415PC is a translucent polyester film differentially coated with a removable/repositionable, low tack, adhesive on one side (back/liner side) and a permanent, high tack, adhesive on the other (face/exposed side). Unlike the other differentially coated tapes on the web site the removable side on this tape is also repositionable so its good when you need multiple openings and closings. Also its removable low tack side offers only nominal adhesion so its good for paper mailings since it will not cause delamination from most paper stock.
Scapa S301 is a clear UPVC film tape coated on both sides with an exceptionally high tack, high peel, acrylic adhesive system. It offers excellent adhesion even to demanding surfaces such as sports jerseys. It also meets the compositional requirements of FDA regulation 21 CFR175.105 (adhesives) for indirect food contact.
3M 4952 VHB tape is a closed-cell firm acrylic foam which is coated on both sides with a low-surface energy synthetic adhesive. This is the tape in the 3M VHB family best suited to bond to many lower surface energy substrates including many plastics and powder coated paints. The tape offers excellent adhesion, durability and solvent and moisture resistance.
