Material Features

Black PET Electrical Insulation Tape — ≥5kV Dielectric Strength

Biaxially oriented black PET film backing provides dielectric strength ≥ 5kV — delivering reliable electrical insulation for wire harnesses, cable bundles, motor windings, and transformer coils in automotive, industrial, and electronics manufacturing applications.

Black Polyester Masking Tape — Complete Light Blocking

The fully opaque black PET film backing blocks 100% of visible and near-infrared light — making this black polyester acrylic tape the preferred choice for photosensitive component protection, optical assembly masking, and light leakage prevention in precision electronics.

High Temp Masking Tape — 150°C Heat Resistance

Withstands continuous temperatures up to 150°C and short-term peaks up to 180°C — maintaining electrical insulation integrity and mechanical performance in automotive underhood environments, powder coating processes, and high-temperature assembly operations.

Solvent-Based Acrylic Adhesive — Long-Term Stability

Thispolyester tape uses solvent-based acrylic adhesive — offering superior aging resistance, moisture resistance, and chemical resistance versus rubber-based alternatives, with residue-free removal after extended application periods.

Clean & Stable Removal

Leaves zero adhesive residue after removal — critical for precision PCB masking, photosensitive component protection, and electronics assembly where surface cleanliness is essential.

Applications of Black Polyester Acrylic Tape

• Black PET Electrical Insulation Tape — Wire Harness & Cable Wrapping
  The preferred polyester tape for automotive wire harness wrapping, cable bundle insulation, and motor coil protection — dielectric strength ≥ 5kV provides safe electrical insulation while black color identifies insulated areas on complex wiring assemblies.
• Light Blocking — Photosensitive Component Protection
  Complete opacity of black PET film blocks 100% of visible and near-infrared light — protecting photosensitive sensors, optical components, and display assemblies from light exposure during manufacturing, testing, and assembly processes.
• Black Polyester Masking Tape — High Temp Masking
  Used for high temperature masking in powder coating, anodizing, and electronics assembly — black color provides high visibility contrast on light-colored substrates for accurate tape placement and complete removal confirmation.
• Transformer & Motor Insulation
  Provides reliable inter-layer electrical insulation for transformer coils, motor windings, and capacitor wrapping. Dielectric strength ≥ 5kV and 150°C heat resistance meet demanding thermal and electrical performance requirements.
• PCB Masking & Electronics Assembly
  Protects PCB components, connector pads, and precision zones during wave soldering, SMT reflow, and selective plating — clean residue-free removal leaves no marks on sensitive PCB surfaces.
