PP double-sided copper platingTechnology has a wide range of applications in multiple fields, and its unique performance makes it an ideal choice in many industries. This article will delve into the advantages and disadvantages of double-sided copper plating on PP from the perspectives of its chemical stability, corrosion resistance, and bonding strength with copper.
Chemical stability is one of the most outstanding properties of PP double-sided copper plating. PP material itself hardly reacts with acids and bases, and can withstand the corrosion of many chemical substances. This characteristic makes PP double-sided copper plating commonly used in the production of various chemical pipelines and fittings. For example, in the chemical industry, PP double-sided copper plated pipelines can ensure the stability and durability of pipelines when transporting highly corrosive substances such as acids and alkalis.
In addition, the corrosion resistance of PP double-sided copper plated material is also very superior. In certain environments such as high temperature, humidity, or the presence of harmful gases, many materials are prone to corrosion or damage, but PP double-sided copper plating can effectively resist these damages. This makes it widely used in some special work environments, such as marine engineering, petrochemical industry, etc.
However, it should be pointed out that the disadvantages of PP materials also exist. Firstly, the thermal performance of PP material is relatively poor. In high temperature environments, PP materials are prone to softening and deformation, which affects their service life and stability. Secondly, the interface bonding force with copper is relatively small. Compared to PET material, PP double-sided copper plating has weaker adhesion and is prone to delamination. Therefore, for some applications that require high-strength connections, PP double-sided copper plating may not be the most ideal choice.
At present,
PP double-sided copper platingThe process mainly adopts a two-step method of dry and wet methods. Firstly, a layer of copper film with a thickness of 20-70nm is deposited on the surface of PP substrate using magnetron sputtering technology to achieve metallization of the film surface. Then, the copper film is thickened to 1 µ m by electroplating to increase its conductivity and mechanical strength.
in summary,. However, its poor thermal performance and relatively low bonding strength with copper are its disadvantages. The use of dry PP double-sided copper plating has superior chemical stability and corrosion resistance, and is widely used in the production of new energy vehicle battery current collectors and accessories through the two-step process of wet and dry methods, which can achieve the preparation of PP double-sided copper plating. For applications in different fields, we should comprehensively consider their advantages and disadvantages based on specific needs and choose suitable materials.
