POLYETHYLENE CLOSED CELL FOAM TAPE
Ambassador Industrials Polyethylene (PE) closed cell foam tape is a lightweight and high-performance sealing solution designed to prevent the ingress of water, air, and dust across a wide range of industrial and construction applications.
Manufactured from chemically cross-linked polyethylene foam, this tape offers excellent conformability, cushioning, and bonding performance. Its closed-cell structure ensures zero moisture absorption, making it highly effective for long-term sealing, insulation, and mounting applications.
With low thermal conductivity and strong adhesive properties, PE foam tape is widely used in glazing, fabrication, and general-purpose sealing where a clean, durable, and cost-effective solution is required.

Technical Advantages
Lightweight & High Performance
PE foam tape offers an excellent strength-to-weight ratio, making it easy to handle while maintaining structural integrity in sealing and bonding applications.
Excellent Sealing & Insulation
Its closed-cell structure prevents air, water, and dust penetration, while also acting as a thermal barrier due to its low thermal conductivity
Strong Adhesion & Conformability
With a hot melt adhesive system, the tape provides strong initial tack and bonds effectively to metals, plastics, and painted surfaces—even on slightly uneven substrates.
Chemical & Moisture Resistance
Polyethylene foam is chemically inert and resistant to many common substances, ensuring durability in diverse industrial environments.
Limitations
- Lower temperature resistance compared to EPDM or PVC/Nitrile
- Not suitable for high-temperature or heavy load-bearing applications
- Moderate UV resistance (best for indoor or semi-exposed environments)
For extreme outdoor or high-temperature use, EPDM or PVC/Nitrile foam tapes are recommended.
Frequently Asked Questions
Yes. PE foam tape provides strong initial tack and is suitable for mounting applications such as trims, panels, and lightweight components.
PE foam is more rigid, lightweight, and cost-effective, making it ideal for static sealing. EPDM, on the other hand, is better suited for flexible outdoor applications requiring high weather resistance.
Yes. It is chemically inert and does not react with painted or coated surfaces when paired with a quality adhesive system.
