Avery Dennison FM 7669 – Premium Double-Coated Black PE Foam Tape
Avery Dennison FM 7669 is a 200-micron double-coated black polyethylene (PE) foam tape engineered for high-end mounting applications in smart devices and electronics. Its modified acrylic adhesive provides excellent bonding performance, making it particularly suited for applications such as mobile phone assembly and lens bonding. FM 7669 delivers consistent performance in industrial environments that demand dimensional stability, high-temperature resistance, moisture resistance, and UV durability.
Key Features:
Modified Acrylic Adhesive: Offers strong initial tack and long-term bonding strength.
Closed-Cell Black PE Foam Carrier: Provides cushioning, excellent conformability, and consistent performance across a variety of surfaces.
Poly-Coated Kraft Release Liner: Ensures smooth handling and precise application.
Benefits:
High Adhesion Across Substrates: Bonds effectively to a wide range of materials, including low surface energy surfaces.
Excellent Cohesion: Provides high dynamic shear strength and push-out resistance, ensuring reliable bonding under stress.
Temperature and UV Resistant: Maintains structural integrity under extreme conditions.
Moisture and Dimensional Stability: Performs reliably in humid environments without deformation.
Waterproof Performance: Certified IPX7, making it suitable for electronics and moisture-sensitive applications.
Construction:
Liner: White Poly-Coated Kraft (PCK)
Adhesive: Modified Acrylic (both sides)

Maximum Continuous Operating: 212°F / 100°C
Maximum Intermittent Operating: 248°F / 120°C
Application Guidelines:
Ensure the surface is clean, dry, and free from grease or oil before application.
Bond strength depends on the amount of adhesive-to-surface contact, pressure, and time.
Different substrates and environmental conditions may affect performance.
Storage and Shelf Life:
One-year shelf life when stored at 18–22°C (64–72°F) with 30–70% relative humidity, away from direct sunlight, in original packaging.
Avery Dennison FM 7669 combines advanced adhesive technology with a robust foam carrier to provide high-performance bonding solutions for electronics and industrial applications. Its superior adhesion, resistance to environmental stressors, and waterproof performance make it an ideal choice for demanding assembly and mounting tasks.
