Matte Side Treated Low Profiles Rolled Copper Foil Black and red color
Treated Low Profiles Rolled Copper Foil with Black/Red Matte Side
Rolled Copper Foil characteristic
During the downstream heating process, the material will undergo annealing changes at a temperature of 145°C within half an hour, The tensile strength and hardness of the material are reduced, and so the elongation is greatly increased, which provides sufficient elongation for the later bending and stretching of the flexible LED, The finished LED is not easy to break during the stretching and bending process.
