What are the main power adapter shell, material composition? Everybody is not strange to the power adapter, electronic products in recent years, more and more rich, all kinds of international certification, the use of the power adapter is becoming more and more wide, the universal power adapter shell material information to everyone. The power adapter is usually made of high-density plastic material. Plastics can be divided according to the use common class, heat resistance, flame retardant grade, electroplating, etc. We use the common power adapter main plastic PC, ABS and PC + ABS. 1, the properties of polycarbonate (PC plastic PC) Thermoplastic resin is a kind of strength. Characterized by (1) high strength, tensile strength of 69 mpa, the bending strength of 96 mpa. (2) high temperature resistant, long-term use can be resistant to 130 degrees Celsius temperature environment. (2) good transparency, non-toxic. (4) raw material color and surface coating is better than ABS. PC material in a wide range of temperature and humidity has a good and a constant electrical insulation, is a good insulating material. At the same time, its good fire resistance and dimensional stability, in the electronic industry has formed a broad application field. 2, the characteristics of ABS plastics acrylonitrile Butadiene - Styrene copolymer ( ABS) Is a kind of high strength, good toughness, easy processing and molding of thermoplastic polymer material structure. Can in - 25 ℃ ~ 60 ℃ under the environment of normal performance, and has good formability, processing the product surface is bright and clean, easy to dyeing and electroplating. ABS material performance characteristics: (1) low intensity, 43 mpa tensile strength, flexural strength of 79 mpa. (2) don't heat resistance, use for a long time temperature shall not be higher than 60 degrees Celsius. (3) liquidity, coloring and surface coating and plating performance are good. ABS material used in household appliances, panels, masks, assembly, accessories, etc. , especially in household appliances, such as washing machines, air conditioners, refrigerators, electric fans, dosage is very large, the other in terms of plastic modification, application is very wide also. 3, PC + ABS plastic properties of acrylonitrile - Butadiene - Styrene copolymer ( ABS) Is a kind of common thermoplastic polymer. Pc and ABs composite material, in front of the two characteristic, excellent processing performance, good liquidity, high strength, 56 mpa tensile strength, bending strength 86 mpa) 。 PC + ABS material is easy to machining, good dimensional stability and surface gloss, easy painting, coloring, also can undertake spraying, electroplating, metal welding and adhesive and other secondary processing performance. Due to the nature of ABS combines the characteristics of three kinds of components, make it has excellent comprehensive performance, become the electrical components, household appliances, computers, and instrumentation plastic one of first choice.
