What is Tesa 66425?
Tesa 66425 is a high-performance, multi-layer, double-sided foam tape engineered for the assembly of delicate electronic components. Its unique structure combines a soft closed-cell PE foam core, PET reinforcement layers on both sides, and strong modified acrylic adhesive, making it suitable for permanent bonding and easy rework without heat. The tape offers outstanding dimensional stability, high shear resistance, and exceptional weatherproofing, ensuring reliable performance in demanding environments.
Composition and Structure
- PE foam core: black closed-cell soft PE foam for excellent cushioning, shock absorption, and stress dispersion
- Reinforcement layer: black PET films on both sides to enhance strength, dimensional stability, and die-cutting performance
- Adhesive type: modified acrylic adhesive on both sides for high initial adhesion and long-term holding power
- Color: black for better concealment and integration with devices
- Total thickness: 280µm (including 50µm release paper)
- Width: up to 940mm (customizable)
- Length: 100m large rolls for high production efficiency
Key Properties
- High shear strength for stable and secure bonding
- Good compressibility and adaptability to uneven surfaces
- Excellent die-cutting and processing performance for customized shapes and sizes
- Non-thermal reworkable design for easy removal and repair without heat tools
- Strong push-out resistance to prevent displacement under external force
- High UV aging resistance and moisture resistance for long-term durability
Applications of Tesa 66425
- Screen and lens bonding in tablets and laptops
- Fixation of touch panels and display modules in electronic devices
- Assembly of precision electronic components requiring strong bonding and future rework
- Applications demanding high bonding strength, dimensional stability, and weather resistance
Features & Benefits of Tesa 66425
- Multi-layer structure: ensures strength, flexibility, and precise processing
- Reworkable without heat: soft foam and PET layers allow for clean removal during repairs
- High bonding strength: modified acrylic adhesive provides strong and durable adhesion to glass, PC, steel, and other materials
- Shock absorption: soft PE foam disperses impact and prevents component damage
- Weather resistance: maintains performance under UV exposure and high humidity
- Production efficiency: large roll format reduces pre-die-cutting lamination steps and improves consistency
Comparison with Other Adhesive Tapes
- Compared to standard PE foam tapes: adds PET reinforcement for superior strength and dimensional control
- Compared to non-reworkable tapes: allows for cost-effective, easy repairs without heat tools
- Compared to single-layer foam tapes: offers better die-cutting, handling, and rework features for complex shapes
