Product Overview
What Is Mylar Tape?
Mylar tape is an electrical insulation tape made with PET polyester film backing and pressure-sensitive adhesive. It is commonly used where thin film insulation, dimensional stability, and clean application are required.
For industrial buyers, the key selection points are backing thickness, adhesive type, color, roll size, temperature requirement, and whether the tape needs to be slit, sheeted, or die-cut for assembly.
Common Purchase Considerations
Electrical Insulation
PET film provides stable insulation for transformers, motors, coils, batteries, and electronic components.
Assembly Fit
Width, length, color, and format should match the production process, not only the nominal tape specification.
Custom Supply
CT Tape can support slit rolls, sheets, die-cut parts, and OEM packaging for different order requirements.
Final specification should be confirmed according to insulation requirement, working temperature, substrate, and converting method.
Key Features
Why Buyers Choose Mylar Tape
Mylar tape is selected for applications that need thin PET film insulation, stable handling, and flexible converting options for electrical and electronic assembly.

Polyester film backing helps maintain shape and insulation performance during wrapping, masking, and assembly.
Electrical Insulation
Suitable for transformer, motor, coil, battery, and component insulation where a thin film barrier is required.
Clean Process Fit
Acrylic adhesive options support stable bonding for industrial assembly without adding unnecessary material bulk.
Color Identification
Multiple color options can help production teams identify insulation positions, batches, or assembly zones.
Converting Ready
Material can be supplied as slit rolls, sheets, or die-cut parts according to production and packaging needs.
Typical Applications
Where Mylar Tape Is Used
Mylar tape is commonly selected for electrical insulation and process protection in components that require thin PET film, stable handling, and custom converted formats.
Transformer Insulation
Used for layer insulation, wrapping, and protection in transformer production and repair.
Motor and Coil Winding
Helps insulate coils and wound components where thin film coverage and stable handling are needed.
PCB Masking
Applied during electronic assembly or soldering processes where temporary film protection is required.
Battery Pack Insulation
Used for insulation, spacing, and component protection in battery modules and related assemblies.
Cable and Wire Wrapping
Suitable for wrapping, marking, and protecting cable or wire areas that need a thin insulation layer.
Component Protection
Converted rolls or die-cut parts can protect electronic parts during assembly, handling, or shipment.
Technical Options
Mylar Tape Specifications
The following specifications are common purchasing references for PET Mylar tape. Final values should be confirmed by insulation requirement, working temperature, adhesive grade, size, and converting format.
Reference Specification Table

| Jumbo Roll Width | Up to 1270mm reference jumbo width, with slit widths supplied according to production and packaging needs. |
| Service Temperature | Typical reference range: -40°C to 130°C. Higher temperature requirements should be confirmed by material grade and test condition. |
| Electrical Insulation | Used for transformer, motor, coil, battery, PCB, and electronic component insulation. Dielectric performance should be confirmed by final construction. |
| Adhesion to Steel | Reference value around 6 N/25mm depending on adhesive grade, backing thickness, and test method. |
| Holding Power | Common reference value: ≥24 hours under standard test conditions. Final performance depends on adhesive grade and application surface. |
| Custom Converting | Slitting, rewinding, sheeting, kiss cutting, die cutting, and OEM packaging are available by size, drawing, or sample. |
For purchasing reference
Common options and typical ranges help buyers compare materials before inquiry, but they should not be treated as a final guaranteed specification.
For final confirmation
Please confirm thickness, width, length, color, adhesive grade, temperature requirement, and converting format before sample or bulk production.
