Polyester Film Tape-PET Tape/Mylar Tape

Description

• Material and construction

  • Base: Polyester film (PET/Mylar) provides high dielectric strength, dimensional stability, and good mechanical toughness.

  • Adhesives: Available silicone adhesive or acrylic adhesive coatings, chosen to match electrical insulation, heat resistance, and environmental requirements.

  • Backing: Flat film with clean release characteristics to permit reliable wound-insulation applications and easy removal when needed.

• Key properties

  • Electrical insulation: Excellent dielectric strength and breakdown resistance suitable for interlayer and coil insulation in motors and transformers.

  • Thermal performance: Class B insulation (130°C) for typical transformer and motor applications; suitable for short-term higher-temperature exposure as per adhesive specification.

  • Mechanical: High tensile strength, good abrasion resistance, and clean peel with minimal residue.

  • Chemical resistance: Generally resistant to common oils, solvents, and humidity typical in electrical equipment environments.

• Advantages for applications

  • Uniform thickness control and tight dimensional tolerances aid reliable coil winding and insulation lap.

  • Optional adhesive systems (silicone or acrylic) provide varying levels of heat resistance, UV stability, and dielectric performance to suit specific end-use sets.
