0.125mm PET Film
This 0.125mm (125 micron) PET film is built for the electrical and electronic side of the business. With a breakdown voltage of 19.5 kV, volume resistivity of 3E+17 Ω·cm, and UL746B rating of 105°C electrical / 105°C mechanical, it handles the kind of stress that thinner films simply cannot. At the same time it keeps the good transparency, dimensional stability, and handling properties that make polyester film so easy to convert.
