The name of the product: polyimide film line. Low product introduction: this product is on the high quality copper (aluminum) conductor, well-spaced winding and polyimide film and polyimide fluorine compound film, 4.6 after heating composite fluorine 4.6 melt in the history of film, thin film between the conductor and bonded into a whole. The product has excellent voltage resistance and insulation thickness is thinner, heat resistance up to 220 â??, is mainly used in motor, reactor, electric welding machine or other similar electric product winding. The electroless copper (aluminum) wire produced by extrusion process is the most ideal material for producing polyimide film. Standard: GB/ t7673-2008 and enterprise standards. Production scope: Aluminum flat wire Narrow side size a:1.00mm - 8.00mm. Wide side size b:3.00mm - 25.00mm. Copper flat wire Narrow side dimension a:0.80mm -- 5.60mm. Wide side size b:2.00mm - 16.00mm. Copper aluminum round wire Diameter: 1. 1. Please contact us if you choose the above range. Low material: Aluminum flat wire should comply with the regulations of GB5584.3-2009, when 20 â??, the resistivity not greater than 0.0280 © was/m Copper flat wire should comply with the regulations of GB5584.2-2009, when 20 â??, the resistivity not greater than 0.017241 © was/m The polyimide film line should be free of cracking to the bare conductor when the diameter of the round rod is bent and the narrow side is bent.
