17.4 kV Breakdown Voltage and 221 MPa MD Strength from a PET Polyester Film Supplier Built for Volume Orders
Product Overview
At 100μm, insulation film moves into a different class. It is no longer just a thin dielectric layer — it has to carry higher voltage, resist deformation, and stay flat through heavy converting. The 100μm PET Polyester Film hits those requirements with a 17.4 kV breakdown voltage, 221 MPa MD tensile strength, and 0.1% TD thermal shrinkage. But those numbers only mean something if the PET Polyester Film Manufacturer behind them can reproduce them at scale.
Technical Characteristics
The following values are typical data for the 100μm specification. They are not intended as limiting specifications.

- Tensile Strength: MD 221 MPa / TD 223 MPa
- Elongation at Break: MD 163% / TD 150%
- Thermal Shrinkage at 150°C, 30min: MD 1.0% / TD 0.1%
- Breakdown Voltage: 17.4 kV
- Volume Resistivity at 20°C: 2E+17 Ω·cm
- Dissipation Factor at 20°C, 1kHz: 42
- Coefficient of Friction: μs 0.6 / μd 0.4
Key Properties
- 17.4 kV breakdown voltage for heavy insulation duty
- Balanced MD/TD tensile strength for stable winding
- Very low TD shrinkage for dimensional control
- Consistent batch performance from a qualified factory
Applications
100μm PET Polyester Film is used for electrical insulation, flyback transformers (FBT), choke coils, wire insulation and cable tape, flexible printed circuits (FPC), membrane switches, die-cut insulation parts, and spiral tube converting. This gauge is common in electrical, electronic, and flexible circuit manufacturing where higher insulation margins are required.
