Geothermal membrane is a type of electric heating film, which is a heat-conducting membrane that uses electricity to generate heat. Because of its bottom power consumption and controllability, it is an effective alternative to traditional heating. Its substrate is transparent PET polyester film, and the heating media is made of special conductive ink, attached with silver paste and conductive metal convergence strip as conductive lead, and finally laminated by heat pressing. The copper foil products produced by CIVEN METAL are ideal for electric heating film sink strips because of their high purity, good surface finish, high precision and low burr in the slitting section. At the same time, in order to better extend the overall life of the product, CIVEN METAL can also electroplate the surface of the material to protect the metal, so as to maximize the use cycle of the material.Copper Foil High-precision RA Copper Foil Tin Plated Copper Foil Nickel Plated Copper Foil *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
