Power bank shell material, how to choose?

　　Large capacity smart phones, tablet computers and other digital products in our daily lives more and more popular, which directly led to the portable charger power bank development. Many readers now have become accustomed to in their own carry bag and a power bank that can charge digital devices at any time, its compact lightweight nature provides us with a great convenience.

　　1. manufacturers currently on the market of power bank shell material

　　Mobile power supply is our most contact with the shell, which is also when we buy products for the entire power bank first impression. Housing can also batteries and circuit boards play a protective role, they appear to prevent damage in daily use.

　　Currently housing mobile power on the market is basically divided into two categories: metal and plastic materials. Due to cost and convenience needs, most of the current mobile power market have adopted the lightweight, inexpensive, beautiful and easy processing of the plastic housing, while most of ABS or ABS / PC plastic material, having impact resistance, heat resistance, low temperature resistance, surface gloss and good features, and easy to paint coloring can also surface plating and electroplating operations.

　　2. The flame retardant housing status of power bank on the market

　　???????However, when we search the Internet mobile power plastic shell found, uneven product quality, price from fifty-six cents to have seven or eight dollars, the most important difference is that the flame retardant material. Power bank shell has good flame retardant properties, even if the mobile power inside for prolonged housing also less prone to cause spontaneous combustion due to circumstances beyond batteries self-extinguishing after ignition of the housing.

　

　　3. Power bank supply housing that selection retardant materials

　　???????PC / ABS Despite its good impact resistance, heat resistance and surface gloss are widely used in mobile power shell, but still there is a huge security risk, PC / ABS PC in the main chain containing benzene ring, can be reduced when the combustion synthesis of aromatic carbon, can be self-extinguishing, but dropped the burning of the melt combustion; and will produce thick smoke and choking odor ABS combustion, which is why ordinary mobile power shell ignited after produces thick black smoke and accompanied by reasons for the burning of the drip, drip of these burning combustion will lead to the surrounding clothing, flooring, purses and other items, causing a larger fire, and thick black smoke and smell will directly lead to people choked to death, and therefore a great security risk.

　　Although retardant class PC / ABS has been developed, but due to higher costs, lower levels of flame-retardant, the application still has some shortcomings, it is difficult to be widely applied to a mobile power supply housing. More importantly, being drafted in the GB mobile power will inevitably move its fire-retardant properties of the housing has a strict standard, once introduced, flame retardant non-compliance of PC / ABS, ABS will be eliminated by the market, the next generation power shell material is what really worth mobile power shell modified plastics manufacturers and suppliers of common concern.

　　4. Does retardant PP Housing material for next-generation power bank of choice?

　　Retardant PP has excellent flame retardant properties, the price has more advantages and more environmentally friendly features, has been in hiding in application areas such as socket, wall switch, home, etc. only successful alternative flame-retardant ABS products.

　　Compared to other flame retardant products, fire-retardant PP has a higher glow wire (GWFI) and resistance to tracking index (CTI), can be more effective protection against fire or electrical leakage, even if it does not produce combustion of the fuel drops or thick smoke, can really achieve effective protection, electrical safety effect. In addition, the product has a good fire-retardant PP coloring, enhance the overall quality of the product appearance, to a certain extent, it can replace the spraying process.
