New energy vehicle charging piles have become a rigid demand, and modified plastic materials will be promising!

The future market for charging piles?

At present, many provinces have proposed to speed up the construction of charging piles in expressway service areas. Jiangxi proposed to achieve full coverage of charging piles in expressway service areas by the end of 2022; Anhui proposed that all expressway service areas and main roads in the province will be built into charging stations by 2023; in addition, Henan, Shandong and other provinces have also issued relevant announcements. policy. At the same time, Beijing, Shanghai, Guangdong and other places announced plans for the promotion of charging and swapping infrastructure. With the development of the charging pile market, the market for modified plastics will also increase.

Modified plastic materials, as an important part of advanced polymer materials, are now widely used in various parts of automobile charging piles.

The charging pile shell made of halogen-free flame-retardant PC material or halogen-free flame-retardant PC alloy material not only meets the protection requirements of possible collisions during transportation, installation and use, but also suits its complex operating conditions.

As a charging gun shell, in addition to flame retardancy, electrical insulation, and weather resistance, it also needs to have good rigidity and toughness to avoid damage caused by falling and vehicle rolling. At the same time, it has a good appearance. It is recommended to use halogen-free flame retardant and weather resistance. PC and its alloy materials.

The charging connectors, including sockets and plugs, are directly connected to the wires and need excellent electrical insulation, flame retardancy, and heat resistance. At the same time, in order to meet the long-term plug-in service life requirements, the materials need excellent mechanical properties, it is recommended Use halogen-free flame-retardant reinforced nylon material.

Since the long-term service temperature of the charging pile cable is -40℃~105℃ and -40℃~125℃, the cable requires oil resistance, halogen-free flame retardant, weather resistance, aging resistance, flexibility, low temperature resistance, etc. Therefore, the inner sheath can use halogen-free flame-retardant TPE and TPU, and the outer sheath can use PVC, halogen-free flame-retardant elastomer, etc.

With the continuous promotion and application of new energy vehicles, miniaturization and lightweight of charging facilities will be the future development direction. Some high-performance new modified plastic materials and other elastomer materials will be engineered in charging facilities. Chemical applications, helping the new energy industry. New energy will radiate more industries and materials, and there will be a lot to do in the future!
