6520/6521Polyester film/Presspaper flexible Laminate is a two-layer
flexible composite material.
According to different thicknesses of Polyester film, 6520/6521
Polyester film/Presspaper can be divided into 6520-23 6520-36
6520-50. The thicker Polyester film you choose, the higher
electrical strength is.
Product Features:
-Insulation class: E class (120 ℃) - 6520/6521 Polyester film/Presspaper has high mechanical strength
and excellent dielectric property.
Product Applications:
6520/6521 Polyester film/Presspaper flexible composite material is
