Why is the copper surface easy to rust?

In the electronics and electrical industries, copper or copper alloy materials are often used, but the copper surface is very easy to rust. If rust or discoloration occurs, it will affect the appearance, reduce the electrical conductivity, and the equipment may fail. Many companies choose VCI Paper for Multimetals to protect copper parts, but how does VCI Paper for Multimetals prevent corrosion on the copper surface?

Common anti-rust methods:

Some companies will apply anti-rust oil to copper parts, but the anti-rust oil can easily contaminate the copper surface, and it needs to be cleaned before subsequent use to increase the processing process.

Some companies use ordinary anti-rust paper to wrap, but ordinary anti-rust paper can only isolate part of the air, has poor moisture resistance, and will rust during long-term storage or transportation.

Some companies also use vacuum packaging, which is costly and complicated to operate, and is not suitable for batch copper protection.

Our VCI Paper for Multimetals is easy to use, efficient and environmentally friendly, and more and more companies choose to use VCI paper.

What is VCI paper?

VCI Paper for Multimetals stands for gas phase anti-rust paper. It does not need to be in close contact with the metal surface directly. As long as it is in a closed packaging environment, it can form a protective layer on the metal surface by releasing gas phase anti-rust molecules to achieve anti-rust effect. For copper and copper alloys, VCI Paper for Multimetals can solve the corrosion problem of copper in a targeted manner, which is very suitable for the protection of copper parts in the electronics and electrical industries.

How does VCI paper prevent the copper surface from rusting?

The high-quality VCI Paper for Multimetals surface will be coated with PE film, which can effectively block external moisture, dust and harmful gases from entering the interior of the package.

The gas phase rust inhibitor in VCI Paper for Multimetals will slowly release anti-rust molecules. These molecules will diffuse evenly in the airtight package and actively adsorb on the copper surface to form an ultra-thin protective film. This film can isolate copper from contact with oxygen in the air, and there will be no oxidation reaction.

Trace amounts of sulfur will react with copper to produce black copper sulfide, which will cause discoloration and corrosion of copper parts. Our paper for copper uses a sulfur-free formula, and the self-developed anti-rust ingredients do not contain sulfur, will not have any harmful reactions with copper, can effectively prevent rust, and can ensure the smoothness and electrical conductivity of the copper surface.

Paper for copper market trends:

With the rapid development of the electronics and electrical industries, the amount of copper and copper alloys is increasing, and the requirements for anti-rust of copper parts are getting higher and higher, and the market demand for paper for copper continues to grow. According to the "2024 Global Anti-rust Packaging Materials Industry Report", the market size for special paper for copper for copper and copper alloys has continued to grow in the past three years. More and more companies are choosing paper for copper.

Conclusion:

Paper for copper can effectively prevent rust on the copper surface by isolating the source of corrosion, releasing gas phase anti-rust molecules, and sulfur-free safety formula, and solve the problem of anti-rust of copper parts. Our paper for copper has reliable performance and can also provide customized services, which can be adapted to the protection needs of copper parts in different industries.
