0.188mm PET Film
When insulation has to carry more voltage and survive tougher handling, 0.188mm PET film is the step up. Its 24.6 kV breakdown voltage and 5E+17 Ω·cm volume resistivity place it firmly in the heavy-duty insulation class, while the 188μm gauge gives it enough body to stay flat and stable through winding, die-cutting, and assembly.
