14.9 kV Breakdown Voltage and 216 MPa MD Strength from a PET Polyester Film Factory and Supplier You Can Verify
Product Overview
Mid-gauge insulation film is where buyers often start paying attention to the manufacturer behind the roll. The 75μm PET Polyester Film sits in that zone. It has enough body to handle repeated winding and converting, yet stays thin enough for compact electrical designs. The numbers back it up: 14.9 kV breakdown voltage, 216 MPa MD tensile strength, and just 0.2% TD thermal shrinkage. Those values only hold in production if the PET Polyester Film Manufacturer controls thickness and coating consistency tightly.

Applications
75μm 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 source this gauge for volume production.
