It adopts ultra-high purity electric grade polyethylene glycol terephthalate, and is formed through biaxial stretching by flat film method, which has features of good transparency, non-toxic and tasteless, tensile strength, high temperature, good stiffness, flexural crack, unbreakable; as a kind of typical polar material, it has higher dielectric constant with excellent electric insulation performance, which can keep good electrical property under higher frequency.
It is mainly used for metallized film capacitors and foil type capacitors such as energy-saving light capacitors, HEV capacitors, AC capacitors etc.
3. Representing method of thickness
The nominal value can use the central value of the thin film thickness (integer value such as 3, 4, 5, 10, etc) plus the mantissa (one decimal place). We use Weight method (WMV) to value the thickness.
After slitting and inspection, every roll of the thin film will be packed with PP plastic bags and drying agent to avoid the powder, particles and moisture. Both the two sides of the roll are fixed with foam spacer, support pad and end cap to avoid squeezing during the transportation, and are packed, baled and stacked with cartons, which will be twisted with plastic thin film to avoid powder, particle and moisture.
The film roll should be stored without any forms of impact in a dry place without direct sunlight and water; it cannot be stored for too long time, otherwise the using property of the film will be influenced; once it is stored over 1 year, please re-evaluate all properties of the film roll.
