  Power adapters are not unfamiliar to everyone. In recent years, the types of electronic devices have become more and more colorful, and the application of adapters has become more and more extensive. I don't know how much everyone knows about the materials of the power adapter housing? Follow the charger manufacturer to learn about it!

How much do you know about the material of the power adapter case?(图1)

  1, the characteristics of PC plastic

  Polycarbonate (Polycarbonate commonly known as PC) is a tough thermoplastic. Its characteristics are ① high strength, with a tensile strength of 69MPa and a bending strength of 96MPa. ②Heat resistance, long-term application can withstand 130 degrees Celsius natural environment. ②Good compatibility and non-toxic. ④The color and surface coating of raw materials are not as good as ABS. PC material has excellent and stable dielectric strength within a wide range of temperature and environmental humidity, and is a high-quality insulating layer material. In addition, its excellent flame retardancy and specification reliability make it widely used in the electrical and electronic manufacturing industry.

  2, the characteristics of ABS plastic

  Acrylonitrilebutadiene-butadiene prepolymer (Acrylonitrilebutadiene Styrenecopolymers, commonly known as ABS) is a kind of thermoplastic polymer material structure with high strength, good ductility, and easy production and processing. It is able to behave normally under the natural environment of -25℃~60℃, and has very good formability. The surface of the products produced and processed is smooth, which is convenient for dyeing agents and electroplating processes. The performance characteristics of ABS materials: ① low strength, tensile strength 43MPa, bending strength 79MPa. ②It is not resistant to high temperature, and the long-term application temperature should not be higher than 60 degrees Celsius. ③Good circulation, coloring, surface painting and electroplating process performance. ABS material is used in electrical products, control panels, breathing masks, components, spare parts, etc., especially in electrical products, such as fully automatic washing machines, central air conditioners, refrigerators, electric fans, etc., and the amount of use is very large. At the modification level, the main applications are also very wide.

  3, the characteristics of PC+ABS plastic

  "Acrylonitrile-butadiene-butadiene prepolymer (Acrylonitrile-Butadiene-Styrene, commonly known as ABS) is a general-purpose thermosetting plastic polymer. The materials produced by Pc and ABs, taking the characteristics of the front two, have high-quality forming and production processing performance, good circulation, and high strength (tensile strength 56MPa, bending strength 86MPa). PC+ABS material is convenient for production and processing, with good production and processing specifications and good surface gloss. It is very easy to spray and color. It can carry out secondary production and processing properties such as painting metal materials, electroplating processes, electric welding and bonding. Because the characteristics of ABS combine the characteristics of its three components, it has high-quality comprehensive performance and becomes one of the preferred plastics for electrical components, household appliances, electronic computers, and instrumentation equipment.
