Strictly selects imported PET film and selects world-famous substrates such as Mitsubishi, Toray, and SKC to control product quality from the source. Uniform resistance, strong adhesion, 0 color difference, complete specifications 100~120Ω square resistance value, the change rate before and after heating and white grid knife test is less than 10%, the performance is stable and reliable. Guaranteed color difference value ≤1 between batches; supports different substrates
