What is Tesa 7950?
Tesa 7950 is a high-performance matte black single-sided tape engineered with a 50μm PET substrate and a black modified acrylic adhesive. Designed for superior shading, bonding, and environmental resistance, it is used in sensitive electronic, LED, NFC, and graphite component applications. Its extremely thin construction and strong adhesive system make it suitable for compact and high-demand assemblies.
Composition and Structure
- Base material: PET (polyester) film for dimensional stability and strength
- Adhesive: Black modified acrylic adhesive for reliable and consistent bonding
- Total thickness: 50μm
- Color: Matte black
- Gloss: 2.5%, providing a refined low-reflection appearance
- Cutting method: Requires knife cutting for clean and even separation
Key Properties
- Excellent light-shielding: Prevents light leakage in optical and display assemblies
- Fingerprint and scratch resistance: Maintains surface cleanliness and durability
- High peel and shear strength: Suitable for high-stress bonding applications
- Excellent rebound resistance: Stable even under tension and deformation
- Temperature resistance: 130°C short-term, 60°C long-term
- Stable in harsh conditions: Maintains performance under humidity, heat, and environmental stress
Applications of Tesa 7950
- LED light source or flat panel display fixation: Prevents component detachment during production and use
- Shading of consumer electronic parts: Enhances visual quality and blocks light interference
- Graphite sheet shielding and fixation: Ensures mechanical and thermal stability in electronics
- NFC antenna protection and shielding: Reduces interference and enhances signal stability
- General electronics assembly: Ideal for parts requiring thin, durable, and discreet bonding
Features & Benefits of Tesa 7950
