Double Sided EPDM Foam Tape
Tape Electric is a manufacturer of double sided epdm foam tape for industrial assembly, bonding, and mounting work. This tape uses a resilient EPDM foam carrier, PSA adhesive on both sides, and a removable release liner for clean handling before application. It is made for metal, plastic, glass, painted panels, trim parts, and light components that need controlled gap filling, cushioning, vibration damping, and stable contact after pressure and dwell time.
- Structure: double-coated EPDM foam with PSA on both sides
- Color: black foam, white or yellow release liner
- Thickness: common 0.5 mm-6.0 mm, custom available
- Width: slit rolls, strips, or die-cut pads
- Adhesive: acrylic PSA or hot melt PSA by substrate
- Use: bonding, mounting, gap filling, vibration damping
Product Features
Product Overview
This product is a double coated EPDM foam tape for joining two parts together during production or installation. It is not EPDM pond liner seam tape, roof repair tape, or a single-sided self-adhesive seal strip. The foam carrier gives the bond line compression and recovery, while the two PSA layers contact both surfaces after firm pressure.
For factory use, the tape can be supplied as slit rolls, kiss-cut strips, shaped pieces, or die cut EPDM foam pads on liner. The release liner affects slitting, punching, handling, and placement speed, so approval should check smooth peeling, adhesive lift, pad curl, and adhesive drag on die-cut edges. Actual substrate testing is needed because oil, oxide film, powder coating residue, mold release, texture, and low surface energy can reduce bonding stability on metal, plastic, glass, or painted parts.
Benefits
- Bonds two parts together with PSA on both sides, not only one backed surface.
- EPDM foam carrier fills minor gaps and softens hard contact.
- PSA foam bonding tape can reduce visible screws or rivets in suitable mounting work.
- Foam compression helps absorb vibration in appliance, automotive, display, and enclosure assembly.
- Release liner supports narrow slitting, kiss cutting, die cutting, and cleaner handling.
- Custom width, thickness, roll length, liner type, and adhesive grade can match the application.
How Can Thickness, Foam Density, and Release Liner Affect Assembly Performance?
For double sided epdm foam tape, thickness should match the real bond-line height, not only the drawing size. Thin tape works for nameplates, plastic covers, trim strips, and low-profile mounting where the joint must stay flat. A thicker EPDM foam carrier can bridge small gaps and damp vibration, but too much thickness may allow movement under load. Foam density also changes the result: a softer grade may over-compress, while a firmer grade gives better support. During approval, check compression recovery after dwell time, liner peeling force, and whether die cut EPDM foam pads stay flat without adhesive drag.

Applications
- Mounting plastic trim, badges, decorative strips, and lightweight panels
- Bonding metal nameplates, aluminum parts, and coated metal components
- Fixing glass or display-related parts where cushioning is required
- Appliance, automotive, and enclosure assembly where vibration needs control
- HVAC and equipment assembly where small gaps need controlled compression
- Die cut EPDM foam pads for repeatable production-line placement
What Should Be Checked Before Bonding to Metal, Plastic, or Glass?
Before full production, test this double sided foam assembly tape on the actual part instead of relying only on standard panels. Metal may carry oil, oxide film, or powder coating residue. Plastic can vary by surface energy, texture, recycled content, or mold release agent. Glass usually offers a smooth surface, but dust and moisture can still reduce contact. A practical approval test should include cleaning, firm application pressure, 24 h dwell observation, peel check, shear holding, edge-lift review, and vibration or temperature exposure.
FAQ
Is this tape the same as EPDM pond liner seam tape?
No. It is for industrial bonding and mounting, not waterproof membrane seaming or roof repair.
Can it bond to low-surface-energy plastic?
Some plastics need special adhesive grades or surface treatment. PP, PE, textured plastic, and recycled plastic should be sample-tested first.
Can the tape be supplied as die-cut pads?
Yes. It can be converted into die cut EPDM foam pads, kiss-cut strips, or shaped mounting pieces on liner.
How should the correct thickness be selected?
Choose thickness by bond-line height, gap size, compression requirement, vibration condition, and part tolerance.
