Typically, our products are available in widths of 0.5 to 1.4 meters and in lengths of 1,000 to 20,000 meters per roll.

Copper foil is an extremely thin copper material that can be categorized into calendered copper foil (RA) and electrolytic copper foil (ED) depending on the manufacturing process. Copper foil has excellent electrical and thermal conductivity and is known for its ability to shield electrical and magnetic signals. It is widely used in the manufacture of precision electronic components. With the advancement of modern manufacturing, there is a growing demand for thinner, lighter, smaller and more portable electronic products, which leads to a wider application of copper foil.

 

Copper ions have high reactivity in the presence of air and react easily with oxygen ions to form copper oxide. Although we treat the surface of the copper foil with a room temperature antioxidant process during production, this treatment only retards the oxidation of the copper foil. Therefore, it is recommended to use the copper foil as soon as possible after opening. Unused copper foils should be stored in a dry place, protected from light and away from volatile gases. The recommended storage temperature for copper foils is approximately 25 degrees Celsius with a humidity not exceeding 70%.

 

Cable taping methods include longitudinal taping and cross taping. Cross taping further divides into traverse taping and diagonal taping. Longitudinal taping is used for core wires where no overall stranding is required, and it does not require flexibility. Traverse taping is a high-speed process with good flexibility.

Films laminated aluminum foil with hot melt adhesive are divided into two types: aluminum/PE shielding films and aluminum/PVE shielding tapes. They use MQ-40 high-molecular-weight polymer as heat-sealing glue, which is non-toxic and eco-friendly and complies with the latest version of the EU RoHS environmental regulations. The other type is self-adhesive film laminated aluminum foil, which uses genuine EAA self-adhesive film, ensuring good heat-sealing bonding effects at lower preheating temperatures and long-term stability.

Copper/PET shielding tapes is primarily used in various fields, such as extremely fine coaxial wires, low-loss antennas (computers), solar cell wires, etc.
