CMT Sandwich Construction Polyimide Film
Specification
CMT sandwich structure polyimide film refers to the top and bottom two layers of polyimide film, metal aluminum as an intermediate layer, three layers overlap together. The CMT Polyimide Film not only has the characteristics of polyimide film but also has the shielding effect and can reflect radar waves. At the temperature of 320℃-350℃ and pressure of 20kgf/ c㎡ will produce viscosity, can be pressed with other materials.
Features:
Corrosion resistant, environment-friendly with halogen free, highest UL-94 flammability rating:V-0.
