Power adapters are usually made of high-density plastic materials. According to the use, it can be divided into ordinary grade, temperature resistance grade, flame retardant grade, electroplating grade, etc. The main plastics used in our common power adapters are PC, ABS and PC+ABS.
1. PC material
Let's start with the power adapter made of pure PC material. Pure PC material has ultra-high strength and elastic coefficient, and can be used in a wide range of temperatures. In addition, PC material has high transparency and free dyeing properties, so it is very good for power adapters to be made in various colors. In addition, this material also has fatigue resistance, weather resistance, tasteless and odorless, harmless to the human body, and is in line with hygiene and safety.
2. ABS material
The characteristics of the power adapter made of ABS are that it has low strength and is not temperature resistant. Generally, the maximum operating temperature cannot exceed 60 degrees Celsius, which is much worse than the PC material. ABS is generally used in household appliances.
3. Synthetic materials of ABS and PC
ABS and PC synthetic materials, taking the characteristics of the former two, have excellent molding performance, good fluidity and high strength. ABS+PC material is easy to process, has good processing dimensional stability and surface gloss, easy to paint, color, and can also perform secondary processing properties such as metal spraying, electroplating, welding and bonding.
So for these three materials, why do we choose pure PC material as the shell of the power adapter? First of all, the PC material has good temperature resistance and can be made into a flame-retardant shell, which ensures the safety of users. Its environmental characteristics are also conducive to environmental protection and human health. At present, the power products of science and technology are basically made of PC flame retardant and environmentally friendly material.
