What Is Mylar Tape?
Direct Answer
Mylar tape commonly describes a PET or polyester-film tape used where electrical insulation, coil wrapping, component fixing, or process masking is required. Select it by film construction, adhesive system, thickness, electrical requirement, and converting format—not by the name alone.
PKG Tape lists a PET-film construction with solvent acrylic adhesive for its Mylar Tape product. The page identifies applications around motors, transformers, capacitors, relays, voltage regulators, coils, and circuit-board protection during an impregnation process.
What Does “Mylar Tape” Mean in an RFQ?
In B2B purchasing, the name alone does not define a complete product. A quotation must identify the film, adhesive, thickness, electrical requirement, color, width, length, roll format, application, and quantity.
| RFQ detail | Why it must be specified |
|---|---|
| Backing material | Confirms the required PET / polyester-film construction. |
| Adhesive system | Solvent acrylic and silicone adhesives have different published product directions. |
| Total thickness | A listed reference value is not automatically valid for every converted thickness. |
| Electrical requirement | Breakdown voltage, insulation requirement, and application conditions must match the project. |
| Color and roll format | Color options and jumbo/log/cut-roll formats affect converting and supply. |
Current PET Film and Adhesive Construction
PET Film Mylar Tape With Solvent Acrylic Adhesive
PKG Tape publicly lists PET or polyester film as the backing and solvent acrylic adhesive as the adhesive system. The reference technical table lists a 50 ± 2 mic total thickness, with 25 mic carrier and 25 mic adhesive thickness.
- Listed thickness options: 0.05, 0.055, 0.06, 0.08, and 0.11 mm.
- Listed colors: red, dark yellow, black, orange, pink, white, light yellow, green, and blue.
- Jumbo, log, cut-roll, and customized formats are listed.
What Is Mylar Tape Used For?
The current Mylar Tape product page identifies electrical insulation and component-related applications. It lists motor stator coil covering, motor coil fixing, power transformer coil wrapping and outer insulation, plus work around transformers, capacitors, relays, voltage regulators, and PCB process protection.
| Publicly listed application direction | Selection question before ordering |
|---|---|
| Motor stator coil covering | Which thickness, adhesive, and electrical requirement does the motor design require? |
| Motor coil fixing | Is the tape used for fixing, insulation, or both? |
| Transformer coil wrapping | What dielectric, temperature, and roll-width requirements apply? |
| Capacitors, relays, and voltage regulators | Is the component surface compatible with the specified adhesive? |
| PCB process protection | Which process, chemical exposure, and removal requirement apply? |
Electrical Insulation Specification Checks
For its reference construction, the Mylar Tape page lists 4.2 KV breakdown voltage and a -10 to +130 C heat-resistant coefficient. It also lists 3 KN/M tensile strength, 45% elongation at break, and 300 N/25 mm peel adhesion.
Confirm film and total thickness
Match the actual ordered PET film and adhesive construction to the project requirement.
Confirm adhesive and application surface
Do not assume a solvent-acrylic construction is interchangeable with every PET tape or component surface.
Confirm electrical requirement and test method
Check the required dielectric and operating conditions against the application documentation.
Confirm converting and supply details
Specify color, width, length, roll format, quantity, packaging, private-label, destination, and documentation requirements.
Mylar Tape vs. PET Silicone Tape
Both listed products use PET film, but they are not interchangeable by default. The adhesive system and documented application direction must guide selection.
| Selection point | Mylar Tape page | PET Silicone Tape page |
|---|---|---|
| Backing | PET / polyester film | PET film |
| Public adhesive statement | Solvent acrylic adhesive | Silicone adhesive |
| Public application direction | Electrical insulation, motors, transformers, coils, components, PCB process protection | High-strength insulation protection and removal of silicone-coated materials |
| Public temperature information | Reference table: -10 to +130 C | Reference table: 25 to 180 C; data is marked for reference only |
For confirmed high-temperature applications and silicone-coated surfaces, review PET tape with silicone adhesive for confirmed high-temperature applications. For the listed solvent-acrylic PET construction, coil-related applications, and color/roll options, review PET film Mylar tape with solvent acrylic adhesive.
What Mylar Tape Is Not
- It is not automatically metalized, aluminum, aluminized, copper, chrome, silver, foil, reflective, or shielding tape.
- It is not automatically double-sided tape, duct tape, or packaging tape.
- It is not a general-purpose cable tape without confirmation of required construction, test data, and compliance documentation.
- It does not carry unverified UL, RoHS, REACH, flame-retardant, residue-free, or chemical-resistance claims.
FAQ
What is Mylar tape made of?
The PKG Tape Mylar Tape page lists PET or polyester film as the backing and solvent acrylic adhesive as the adhesive system. Confirm the ordered construction because thickness, color, and converted roll format can vary.
What is Mylar tape used for?
The product page lists electrical insulation and component-related work including motors, transformers, capacitors, relays, voltage regulators, motor coils, power transformer coil wrapping, and circuit-board protection during an impregnation process.
Is Mylar tape the same as metalized or aluminum tape?
No. The reviewed page lists PET film and acrylic adhesive. It does not list metalized, aluminum, foil, reflective, or shielding construction.
Can Mylar tape be used for cable insulation?
A keyword alone is not enough to confirm cable use. Obtain technical confirmation because a cable assembly can require different construction, test data, and compliance documentation.
How do I choose between Mylar Tape and PET Silicone Tape?
Begin with adhesive system, operating requirement, surface, and documented application. PKG Tape lists solvent acrylic adhesive for Mylar Tape and silicone adhesive for PET Silicone Tape; confirm the required construction before selecting either product.
Need a PET Film Tape Specification or OEM Quote?
Send your application, PET film and total thickness requirement, adhesive preference, electrical requirement, color, roll size, quantity, destination, and private-label needs. PKG Tape can then review the appropriate construction.
