Plain Slitted Polyester Film

It is made of imported alcohol phthalate, which is biaxially stretched. It has the characteristics of high tensile strength, high dielectric strength, high dielectric loss, high loss, high thickness, and large point resistance. It has been widely used in electrical appliances for introduction properties and insulating interlayers. Mainly used in metallized film appliances and arrow-type appliances, such as energy-saving lamps and appliances, and live broadcast packages.
