With the rise of new energy vehicles, charging guns more and more people in the field of vision, especially portable rechargeable gun.What material is the best choice for charging gun shell? Charging safety is the primary consideration charging gun selection, Charging gun material to meet the national standards.
Charger gun housing currently on the market commonly used materials
Imported materials are SABIC LEXAN9930, Bayer's Marolon6487, these two materials have good high temperature impact toughness, flame retardancy and weathering performance. There are also the corresponding domestic PC materials for charging pile shell.
In addition, in order to save costs, some domestic companies now use PC / ABS or PC / PBT material to replace the original PC material.
The advantages and disadvantages of each material
Material selection needs attention
National standards GB / T20234 and GB / T11918 and other materials on the charging pile with the technical indicators have been limited, including physical and mechanical properties (resistance to rolling test), weather resistance, electrical properties, flame retardant properties.
Serie Long charge gun shell material
Based on the requirements of national standard GB / T 20234 for physical properties, weatherability, processability and electrical properties of materials for charging piles, we think PC and PC / ABS materials are ideal.
At present, the main material used for charging dragon shell is PC-2370 T and FRPC / ABS 3370.
