USB-C Adapter Security Risks Are Important May 26, 2017

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

      USB-C 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 USB-C 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, 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, 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, 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.

to sum up

Over the past two years. Whether it is in the mold design, injection molding technology or paint performance has a great breakthrough, with PC material to do the proportion of USB-C Adapter shell is rising. The initial estimate of the current USB-C Adapter shell Pc material with the proportion of more than 50%. ABS temperature and fire performance is poor, easy to melt at high temperatures, the adapter temperature is relatively high, so can not be used, then because of other performance is better, such as wear, so generally used for low-voltage products, such as mobile phones, MP4 and so on. In addition ABS + PC material is also commonly used, the temperature performance than ABS good, but worse than the PC, but also able to fire, so it is also used for some high voltage, relatively low temperature equipment.

     In fact, according to the structural characteristics of material selection: ① when the structural strength of the larger, thick wall, the structure of complex shape should be preferred PC + ABS; ② when the structure is thin, lack of strength, should choose PC. According to the appearance of paint color selection: ① bright, multi-color, strict requirements on the Xu, PC + ABS should be preferred; ② need to do the appearance of plating, should be elected ABS. Export of Japan's USB-C Adapter is mainly used PC + ABS, and even use ABS to do mobile phone shell, export Korea USB-C Adapter with pure PC material.
