Description：
CM Polyimide film formed by sputtering metal aluminum, then develops thin aluminum layer, with one side insulation, the other side high conduct electricity. It not only has the performance of excellent heat resistant, mechanical, chemical stability, radiation resistant, and self-extinguishing, but also EMI shielding, high thermal conductivity. It can be applied in radiation resistant of inner space suit, EMI shielding, seal material, electromagnetic shielding tape, flexible etching wire.
Features:
Corrosion resistant, environment-friendly with halogen free, highest UL-94 flammability rating:V-0.
