Black PET Light Blocking Acrylic Tape 130℃ for Die-Cutting & Insulation

The Black PET Light Blocking Acrylic Tape is a high-performance, multi-purpose adhesive solution engineered for electronics manufacturing, die-cutting operations, and display assembly applications. Constructed with a completely opaque black PET film backing and coated with a stable, high-tack acrylic adhesive system, this tape delivers reliable performance at continuous operating temperatures up to 130℃. The absolute opacity ensures zero light transmission, making it ideal for light blocking in LCD/LED displays and preventing optical interference in sensitive electronic devices. For die-cutting converters, the tape offers excellent tensile strength (>3.2 kN/m) and controlled adhesion, functioning reliably as a waste removal tape, carrier film, or pull-tab assist. In motor and transformer insulation, it provides dependable electrical isolation with a dielectric breakdown voltage exceeding 3.5kV and built-in flame retardant properties. This versatile black polyester tape removes cleanly without adhesive residue, ensuring process efficiency and product quality across multiple industrial workflows.

• Complete Opacity & Light Blocking: The deep black PET film provides 100% light blockage, preventing light leakage in display assemblies, protecting light-sensitive components, and ensuring optical integrity in electronic devices.
• 130℃ Temperature Resistance: Maintains adhesion, dimensional stability, and dielectric properties at continuous operating temperatures up to 130℃, suitable for electronic transformer and motor insulation applications.
• High-Strength Acrylic Adhesive System: Premium acrylic adhesive delivers stable, long-term bonding with peel adhesion >600g/25mm. Provides excellent initial tack with consistent release properties over time—ideal for both permanent insulation and temporary die-cutting processes.
• Flame Retardant Compliance: Engineered with flame retardant properties to meet safety requirements in electrical insulation applications, reducing fire risk in motor windings, transformers, and electronic components.
• Superior Tensile Strength: Tensile strength exceeds 3.2 kN/m, ensuring the tape resists breaking, stretching, or tearing during high-tension die-cutting operations, waste matrix stripping, and automated application processes.
• Excellent Electrical Insulation: Dielectric breakdown voltage exceeds 3.5kV, providing reliable electrical isolation for motor windings, transformer coils, and high-voltage electronic assemblies.
• Chemical & Solvent Resistance: Withstands exposure to common industrial solvents, cleaning agents, and processing chemicals without degradation of the adhesive or backing film.

• Electronic Transformer Insulation: Provides high-temperature electrical isolation and flame retardant protection for transformer windings, coil wraps, and layer insulation in power supply units and electronic ballasts.
• Motor Insulation & Protection: Used for slot liner retention, lead wire anchoring, and coil bundling in electric motors, servos, and small appliance motors requiring 130℃ thermal class insulation.
• Die-Cutting Waste Removal (Matrix Stripping): Functions as a high-strength waste removal tape to cleanly lift and strip waste matrix from kiss-cut labels, gaskets, and precision die-cut parts without tearing or adhesive transfer.
• Die-Cutting Carrier & Liner Applications: Serves as a stable carrier film, backing tape, or transfer sheet in multi-layer die-cutting processes, providing reliable support for delicate materials during lamination and cutting.
• Pull-Tab & Finger-Lift Tapes: Custom-converted into pull-tabs, tear strips, and finger-lift assists for easy liner removal on adhesive products, medical device packaging, and consumer goods.
• LCD/LED Display Light Blocking: Applied around display bezels, backlight edges, and optical film edges to prevent light leakage, block stray illumination, and maintain contrast ratios in monitors, TVs, and industrial displays.
• Optical Component Masking: Protects light-sensitive sensors, lenses, and optical assemblies during manufacturing, coating, and shipping operations.
• Electronic Component Manufacturing: General-purpose high-temperature masking and insulation for PCB assemblies, capacitors, resistors, and other electronic components during soldering and testing.
• Automotive Electronics Insulation: Suitable for under-hood electronic modules, sensors, and wiring harness protection where 130℃ thermal resistance and flame retardancy are required.
