2.3 mm Gray Acrylic Foam Tape is a thick industrial mounting tape for applications that need gap filling, uneven surface compensation, and controlled vibration damping. Double Seal Tape Company is the manufacturer of this gray acrylic foam core tape, supplied with a red PE liner for clean slitting, die cutting, kiss cutting, and assembly handling. With a 2.3mm bond line and typical thickness tolerance of +/-0.20 mm, it helps stabilize automotive accessories, nameplates, decorative trims, and small panels where thin tape may not fully contact the surface.

Product Overview
This 2.3 mm Gray Acrylic Foam Tape is made for mounting parts where surface contact is more important than simply using a strong adhesive. The 2.3mm foam body gives the tape enough thickness to bridge small height differences between molded plastic, painted metal, aluminum plates, coated covers, and slightly curved decorative parts. In sample assembly, this thickness is often chosen when thinner tape leaves dry contact areas, early edge lifting, or uneven pressure marks after pressing.
The tape is built with a gray acrylic foam core and pressure-sensitive acrylic adhesive on both sides. It is not a paper tissue tape, PET carrier tape, PE foam tape, or LED strip tape. The acrylic foam structure provides compression recovery and helps spread stress along the bond line, which is useful when mounted parts face light movement, vibration, or different expansion behavior between plastic and metal.
The red PE liner is included for practical production handling, not only for appearance. It supports clean unwinding, stable kiss cutting, easier liner removal, and better part positioning during manual or fixture-assisted assembly. Double Seal Tape Company can supply jumbo rolls, slit rolls, narrow strips, die-cut pads, and shaped parts according to the bonding area. Before mass use, actual substrates should be tested for 24-72 hours to check peel strength, liner release, edge lifting, adhesive overflow, and visible compression marks.
Benefits
- Fills small assembly gaps: The 2.3mm foam layer improves contact where molded, painted, or curved parts do not sit perfectly flat.
- Reduces bond-line stress: The gray acrylic foam core helps absorb minor vibration and reduce edge stress in automotive accessory and panel mounting.
- Handles converting more cleanly: The red PE liner supports slitting, die cutting, kiss cutting, and manual peel-and-stick installation.
- Works on tested industrial surfaces: Trial samples can be checked on painted metal, aluminum, ABS, PC, and coated nameplate surfaces.
- Keeps tolerances visible: Thickness tolerance, slit-width tolerance, and die-cut tolerance can be confirmed before mass assembly.
- Supports realistic dwell testing: A 24-hour check helps detect early lifting, while 72-hour dwell testing gives a clearer view of final peel behavior.
How does 2.3mm thickness improve mounting on slightly uneven parts?
The 2.3mm thickness is useful when two parts do not meet with perfect surface contact. In automotive accessory mounting, nameplate fixing, and small panel assembly, molded plastic parts, painted metal covers, or curved decorative trims may have small height differences. A thicker gray acrylic foam core can fill these gaps and improve wet-out under pressure. It also creates a softer bond line than thin film tape, helping reduce minor vibration, part movement, and stress concentration after installation. For production evaluation, sample parts should be pressed with the intended assembly pressure and checked after 24-72 hours for edge lifting, peel strength, and compression marks.
Applications
- Automotive accessory mounting, including side trims, small badges, decorative strips, and interior attachment parts
- Nameplate and logo fixing where a thicker bond line helps improve contact and edge stability
- Small panel mounting for equipment covers, appliance panels, control housings, and decorative plates
- Industrial mounting on painted metal, aluminum, ABS plastic, PC plastic, and coated surfaces after sample testing
- Gap filling strips for parts needing uneven surface compensation, vibration reduction, and stable compression
- Die-cut pads or kiss-cut parts for assembly lines requiring fast liner removal and repeatable placement

What should be checked before slitting or die cutting this acrylic foam tape?
Before slitting or die cutting 2.3 mm Gray Acrylic Foam Tape, the tape width, part shape, red PE liner release, and thickness tolerance should be confirmed with real assembly samples. Narrow strips and small die-cut parts need extra attention because thick foam can show adhesive overflow or edge deformation if the tool design is not suitable. For industrial mounting, the converted tape should match the bonding area without stretching, curling, or covering unwanted edges. A practical test should include slit-width tolerance, die-cut edge stability, 24-72 hour dwell observation, and peel testing on the actual painted, plastic, aluminum, or nameplate surface.
FAQ
-
Is this tape suitable for slightly uneven surfaces?
Yes. The 2.3mm foam thickness helps compensate for small gaps and improves contact on mildly uneven parts.
-
Can this tape be die cut into small mounting pads?
Yes. It can be slit, kiss cut, or die cut. Sample testing is recommended to confirm liner release and edge quality.
-
What liner is used on this tape?
It uses a red PE liner for clean unwinding, converting, and easier removal during assembly.
-
Should samples be tested before bulk production?
Yes. Test actual substrates for 24-72 hours to check peel strength, edge lifting, compression marks, and surface compatibility.
