Power adapters are usually made of high-density plastic materials. Plastics can be divided into general grade, temperature resistant grade, flame retardant grade, and electroplating grade according to the application. Our common power adapters use the main plastics: PC, ABS and PC+ABS.
1, the characteristics of PC plastic
Polycarbonate (PC) is a tough thermoplastic resin. Its characteristics are
1 high strength, tensile strength 69MPa, bending strength 96MPa.
2 high temperature resistance, long-term use can withstand 130 degrees Celsius temperature environment.
3. Good transparency and non-toxicity.
4 raw material color matching and surface coating is not as good as ABS. PC materials have good and constant electrical insulation over a wide range of temperatures and humidity and are excellent insulating materials. At the same time, its good flame retardancy and stability make it a broad application field in the electronic and electrical industry.
2, the characteristics of ABS plastic
Acrylonitrile-butadiene-styrene copolymer (ABS) is a thermoplastic polymer structure with high strength, good toughness and easy processing. It can be normal in the environment of -25 ° C ~ 60 ° C, and has good formability, the surface of the processed product is smooth, easy to dye and electroplating. Performance characteristics of ABS materials:
1 low strength, tensile strength of 43MPa, bending strength of 79MPa.
2 is not resistant to temperature, long-term use temperature should not be higher than 60 degrees Celsius.
3 fluidity, coloring and surface coating and plating performance are good. ABS materials are used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as washing machines, air conditioners, refrigerators, electric fans, etc., the amount is very large.
3, the characteristics of PC + ABS plastic
Acrylonitrile-butadiene-styrene copolymer (ABS) is a general-purpose thermoplastic polymer. The synthetic materials of PC and ABS take the characteristics of the former two, have excellent molding processing performance, good fluidity and high strength (wearing strength 56MPa, bending strength 86MPa). PC+ABS material is easy to process, has good dimensional stability and surface gloss, is easy to apply and color, and can be used for secondary processing such as metal spraying, electroplating, welding and bonding. Because the characteristics of ABS combines the characteristics of its three components, it has excellent comprehensive performance and becomes one of the preferred plastics for electrical components, home appliances, computers and instrumentation.
