Product description
Polyester film is an important product for polyester applications in non-fiber fields. At present, they mainly refer to polyester films. It is a film made from polyethylene terephthalate polymer in the ester family, its English abbreviation is, its full name is. This product is mainly made of polyester ( ) chips as raw materials and is biaxially stretched to produce a high-end plastic film with excellent performance. It has high transparency, non-toxic and tasteless, high tensile strength, good stiffness, and anti- Burning cracking, not easy to break, excellent electrical and optical properties, good oxygen and moisture resistance, cold resistance (-℃), heat resistance (℃), and has excellent properties such as chemical corrosion resistance and stable shrinkage.
Capacitor film product features: The product has the characteristics of good insulation performance, good dielectric performance, chemical corrosion resistance, heat shrinkage and stable thickness.
Capacitor film products are mainly used in capacitor dielectrics, as well as insulating layers of transformers and coils.
