What is 3M427?
3M427 is a high-performance silver foil tape produced by 3M. As a die-cut friendly version of 3M425, it combines a soft, thermally conductive aluminum foil backing with a highly engineered acrylic adhesive. This versatile tape delivers exceptional heat and light reflection, chemical and weather resistance, and excellent bonding strength for both indoor and outdoor applications.
Composition and Structure
- Backing: Soft aluminum foil for excellent thermal conductivity and reflectivity
- Adhesive: Engineered acrylic adhesive that withstands high temperature and humidity
- Fire-resistant: Helps reduce fire hazards in sensitive environments
- Soft, conformable construction: Enables easy fitting on curved or uneven surfaces
- Vibration damping capability: Reduces noise and resonance in assembly operations
- Multiple specifications: Available in widths like 2.5 cm, 25.4 mm, and 30.5 cm, with lengths such as 54.86 m, 54.9 m, and 55 m for versatile use
Key Properties
- High temperature resistance from -65°F to 300°F (-54°C to 149°C)
