The power adapter housing is generally made of a plastic material. Of course, some industrial power supplies use a metal casing. We generally have the material of the power adapter housing, mainly ABS material, ABS + PC material, pure PC material. In general, we only use these three materials. Let's take a look at the differences between these materials.
Pure PC material has ultra-high strength and elastic coefficient, and has a wide temperature range. (ABS material can only be used at -25 to 60 degrees), and PC material has high transparency and free dyeability. The power adapter is very good in various colors. In addition, the material is fatigue-resistant, weather-resistant, tasteless and odorless, and is harmless to the human body. It is hygienic and safe.
ABS material characteristics, first low intensity, not temperature, under normal circumstances, the maximum temperature can not exceed 60 degrees Celsius, which is a lot worse than PC material, ABS is generally used in household appliances.
ABS and PC synthetic materials
Taking the characteristics of the former two, it has excellent molding processing performance, good fluidity and high strength. ABS+PC material is easy to process, has good dimensional stability and surface gloss, is easy to apply, color, and can also 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.
In the selection of the power adapter housing material, basically based on pure PC material and PC + ABS, although the cost will be increased before the comparison, the price of the power adapter will be different, but from the environmental protection and safety Said, ABS is getting more and more unmatched in the current market demand! So the power adapter manufacturer reminds you that when you choose the power adapter, try to choose a large manufacturer to buy!
