What is Tesa 7930?
Tesa 7930 is a high-performance matte black single-sided tape designed with a 30μm PET backing and a black modified acrylic adhesive. It provides exceptional light-blocking capability, high electrical insulation, and robust bonding across various surfaces. Known for its resistance to environmental stress, fingerprints, and scratches, Tesa 7930 is widely used in LED displays, graphite sheet protection, and precision electronics.
Composition and Structure
- Base material: PET (polyester) film for durability and dimensional stability
- Adhesive: Black modified acrylic adhesive with high peel and shear resistance
- Total thickness: 30μm, suitable for applications needing robust adhesion and shielding
- Surface gloss: 2.5% matte black appearance
- Color: Matte black
Key Properties
- Excellent light-shielding performance: Ideal for preventing light leakage in sensitive devices
- Anti-fingerprint and scratch resistance: Keeps surfaces clean and protected
- High peel and shear strength: Maintains firm and lasting adhesion
- Dielectric breakdown voltage: 3500V for superior electrical insulation
- Temperature resistance: Up to 130°C (short-term), 60°C (long-term)
- Excellent rebound resistance: Maintains contact under stress and vibration
- Weather resistance: Stable in harsh environmental conditions
Applications of Tesa 7930
- LED light source or flat panel display fixation: Prevents detachment during production and use
- Consumer electronic component shading: Enhances visual quality by blocking light leakage
- Graphite sheet shielding and fixation: Provides mechanical protection and electromagnetic shielding
- NFC antenna protection: Ensures stable antenna performance with minimal interference
- Electronics assembly: Used in components requiring thin, strong, and concealed bonding solutions
Features & Benefits of Tesa 7930
- Superior matte black finish: Enhances product aesthetics and concealment
- Outstanding light-shielding: Prevents backlight bleeding or interference in optical components
- High durability: Withstands stress, temperature, and environmental exposure
- No adhesive residue: Clean removal helps preserve component quality
- Environmentally friendly materials: Supports sustainable development goals
- Easy die-cutting: Compatible with automated manufacturing processes
Comparison with Other Adhesive Tapes
- Tesa 7930 offers greater dielectric strength (3500V) than most general PET tapes
- Its 30μm thickness provides improved mechanical strength compared to ultra-thin models like Tesa 7905 or 7910
- Compared to lighter adhesives, it has enhanced peel, shear, and rebound resistance, ideal for demanding electronics
- Gloss rate of 2.5% makes it more matte than many commercial tapes used for masking or general-purpose applications
