Power Adapter Housing Material Selection

Shenzhen GEO Technology Co.,Ltd | Updated: Jul 19, 2017

  Power adapter housing material selection

  We are no strangers to the power adapter, in recent years, more and more rich electronic products, power adapter is also more and more widely used, Power adapter do not know the power adapter shell material to understand how much? Next Xiaobian with everyone about the power adapter shell material information, we can also use more time to understand, to avoid some security risks.

  Power adapters are usually made of high-density plastic materials. Plastic can be divided into ordinary grade by use, temperature level, flame retardant grade, plating grade. Our common power adapter uses the main plastic PC, ABS and PC + ABS three categories.

  1, PC plastic features

  Polycarbonate (PC) is a tough thermoplastic resin. Its characteristics are ① high strength, tensile strength of 69MPa, bending strength 96MPa. ② high temperature, long-term use can be resistant to 130 degrees Celsius temperature environment. ② good transparency, non-toxic ④ raw material color and surface coating as ABS. PC material in a wide temperature and humidity range has a good and constant electrical insulation, Power adapter is an excellent insulating material. At the same time, its good flame resistance and dimensional stability, so that in the electrical and electronic industry has formed a broad application areas.

  2, ABS plastic characteristics

  Acrylonitrile-butadiene-styrene copolymer (Acrylonitrile butadiene Styrene copolymers, referred to as ABS) is a high strength, good toughness, easy processing and molding of thermoplastic polymer material structure. Can be in -25 ℃ ~ 60 ℃ under the normal performance of the environment, and a good shape, the processing of the product surface smooth, easy to dye and plating. ABS material performance characteristics: ① low strength, tensile strength 43MPa, bending strength of 79MPa. ② not temperature, long-term use of the temperature should not be higher than 60 degrees Celsius. ③ fluidity, coloring and surface coating and plating performance are good. ABS materials used in household appliances, panels, masks, accessories, Power adapter accessories, especially household appliances, such as washing machines, air conditioners, refrigerators, fans, etc., the amount is very large, and in the plastic modification, the use is also very wide.

  3, PC + ABS plastic characteristics

  Acrylonitrile-Butadiene-Styrene (ABS) is a versatile thermoplastic polymer. Pc and ABs synthetic materials, take the front of the two characteristics, with excellent molding processing performance, good mobility, high strength (tensile strength of 56MPa, bending strength of 86MPa). PC + ABS material is easy to process, processing dimensional stability and surface gloss is good, easy to paint, coloring, can also be sprayed metal, electroplating, Power adapter welding and bonding secondary processing performance. As the characteristics of ABS combined with the characteristics of its three components, it has a good overall performance, as electrical components, home appliances, computers and instrumentation one of the preferred plastic.
