Sealing & Bonding
PE Foam Double-Sided Tape & Die-Cut Sealing Gaskets
Our PE foam double-sided tape is built on a closed-cell polyethylene (PE) foam backing, coated on both sides with acrylic pressure-sensitive adhesive (PSA). The closed-cell structure delivers IPX7 waterproofing (IPX8 for cross-linked grades), compresses 20–40% to fill gaps and absorb shock, and is easily die-cut into custom gaskets and shapes.
Why PE foam tape
- IPX7 / IPX8 sealing — closed-cell foam blocks water and dust ingress.
- Gap-filling — compresses to bridge imperfect surfaces and tolerances.
- Vibration damping — cushions bonded parts in moving equipment.
- Weather resistant — UV, humidity and temperature stable for outdoor use.
Typical capabilities
| Thickness range | 0.15 – 3.0 mm |
| Waterproof rating | IPX7 standard; IPX8 on cross-linked PE grades |
| Compression | 20 – 40% for optimal sealing |
| Die-cut tolerance | ±0.05 – 0.3 mm |
| Presentation | Kiss-cut on liner, sheets, tape-and-reel, individual gaskets |
Applications
- Consumer electronics — display sealing, battery pack gaskets.
- Automotive interior — trim bonding, speaker gaskets, sensor seals.
- Appliances — panel mounting and door seals.
- Window/door & solar PV — weather sealing and frame bonding.
FAQ
Can you die cut this into a custom enclosure gasket?
Yes — any 2D gasket shape from your drawing, kiss-cut on a release liner for clean application.
IPX7 vs IPX8 — which do I need?
IPX7 (1 m / 30 min) covers most consumer and outdoor devices. IPX8 (continuous immersion) is for submersible equipment; we source cross-linked PE for that grade.
