12.1 kV Breakdown Voltage and 218 MPa MD Strength from a Reliable PET Polyester Film Factory and Supplier
Product Overview
When buyers search for a PET Polyester Film Manufacturer, they are usually not just looking for a price. They are looking for a supplier who can hold thickness tolerances, keep dielectric performance stable, and deliver the same batch quality again and again. The 50μm PET Polyester Film is a good example of why this matters. At 50μm, it delivers a 12.1 kV breakdown voltage, 218 MPa MD tensile strength, and low 0.1% TD thermal shrinkage — numbers that only hold up in production if the factory behind them is consistent.
Technical Characteristics
The following values are typical data for the 50μm specification. They are not intended as limiting specifications.
- Material: PET (Polyethylene Terephthalate)
- Thickness: 50 μm
- Tensile Strength: MD 218 MPa / TD 235 MPa
- Elongation at Break: MD 184% / TD 172%
- Thermal Shrinkage at 150°C, 30min: MD 1.1% / TD 0.1%
- Breakdown Voltage: 12.1 kV
- Volume Resistivity at 20°C: 4E+17 Ω·cm
- Dissipation Factor at 20°C, 1kHz: 40
- Coefficient of Friction: μs 0.6 / μd 0.4
Key Properties
- 12.1 kV breakdown voltage for reliable thin insulation
- Balanced MD/TD tensile strength for winding and converting
- Low TD shrinkage for dimensional control
- Stable batch-to-batch performance from a qualified factory
Applications
50μm 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. Buyers in electrical, electronic, and flexible circuit manufacturing typically source this gauge in volume.
