Material Features

PET Electrical Insulation Tape — 150°C Heat Resistance

Withstands continuous temperatures up to 150°C and short-term peaks up to 180°C with no softening, delamination, or adhesive migration — meeting the core thermal performance standard for transformer winding and motor coil applications.

Transformer Insulation Tape — Biaxially Oriented PET Film

Premium PET film backing delivers tensile strength ≥120 N/25mm, exceptional dimensional stability, and tear resistance under both mechanical and thermal stress — ensuring precise winding coverage and consistent insulation layers.

Solvent-Based Acrylic Adhesive

Thisyellow polyester acrylic tape uses solvent-based acrylic adhesive — offering superior aging resistance, chemical resistance, and moisture resistance versus rubber-based alternatives, at better cost efficiency than silicone.

Mylar Tape for Transformer — Superior Dielectric Performance

Dielectric strength ≥ 5kV makes this polyester tape ideal for inter-layer insulation in transformer coils, motor windings, capacitors, and PCB component protection layers.

Clean & Stable Removal

Leaves zero adhesive residue after removal — critical for precision transformer winding, PCB masking, and electronics assembly processes.

Applications of Yellow Polyester Acrylic Tape

• Transformer Insulation Tape — Coil Winding
  The industry-standard polyester tape for inter-layer insulation in transformer coils and inductors. Dielectric strength ≥ 5kV ensures reliable electrical separation between winding layers under continuous operational load.
• Motor & Capacitor Insulation
  Widely used as PET electrical insulation tape for motor coil protection, capacitor wrapping, and generator winding — providing stable insulation under continuous thermal and mechanical stress up to 150°C.
• Mylar Tape for Transformer — Coil Wrap
  Functions as a reliable mylar tape alternative for transformer coil wrapping, providing dimensional stability and chemical resistance across a wide range of industrial transformer manufacturing processes.
• PCB Masking & Wave Soldering
  Protects gold fingers, connectors, and solder-free zones during PCB wave soldering and SMT reflow. Clean removal leaves zero residue on circuit boards.
• Lithium Battery & Cable Insulation
  Provides stable electrical insulation and mechanical protection for lithium battery cells, wire harnesses, and cable bundles in EV and industrial equipment applications.

Q1 | What is yellow polyester acrylic tape used for?

Yellow polyester acrylic tape is the industry-standard transformer insulation tape for inter-layer coil winding, motor coil protection, and capacitor wrapping. It is also widely used for PCB wave soldering masking and lithium battery cell wrapping in electronics and EV manufacturing.

Q2 | What temperature can this PET electrical insulation tape withstand?

Thispolyester tape withstands continuous temperatures up to 150°C and short-term exposure up to 180°C — meeting the thermal performance standard for transformer and motor applications, with no adhesive migration or delamination.

Q3 | Is yellow polyester tape suitable for transformer winding?

Yes. This PET electrical insulation tape is specifically designed for transformer winding — it provides dielectric strength ≥ 5kV, stable inter-layer insulation, and clean residue-free removal after the winding process is complete.

Q4 | What is mylar tape for transformer and is this the same?

Yes.Mylar tape for transformer refers to polyester film (PET) tape used in transformer coil winding — this yellow polyester acrylic tape serves the same function, offering equivalent dielectric performance at competitive pricing for industrial-scale transformer manufacturing.

Q5 | Do you support OEM customization?

Yes. We offer full OEM services including custom width, thickness, color, die-cutting, and private label packaging with low MOQ.
