What are the materials of the charger shell? Which is the best?

In this rapidly developing information age, everyone is inseparable from the phones, and the mobile phones have filled our daily life. But have you paid attention to mobile phone chargers? Fire accidents caused by chargers are not uncommon, and there are tens of millions of related searches on the Internet. This article will expand through the following points to let you know how to choose a safe charger.

What are the materials of the charger shell?

ABS material and characteristics

ABS is a thermoplastic polymer material structure with high strength, good toughness, and easy processing. It can perform normally in the environment of -25 degrees to 60 degrees, and has good formability. The processed product has a smooth surface and is easy to dye and electroplate.

The performance characteristics of ABS material,

1. Low strength, tensile strength 43MPa, bending strength 79MPa
2. Not resistant to temperature, long-term use temperature should not be higher than 60 degrees Celsius
3. Good fluidity, coloring and surface spraying and electroplating performance. ABS materials are used in household appliances, panels, masks, assemblies, accessories, etc., especially household appliances, such as: washing machines, air conditioners, refrigerators, fans, etc. The dosage is very large, and in addition, it has a wide range of uses in plastic modification.

PC material and characteristics

PC material is actually a kind of polycarbonate. The famous Nokia mobile phone case was made of this material. This material has high strength, strong durability, and is not easily deformed under high temperature, tasteless and odorless, harmless to human body at the same time.

1. Elastic coefficient, high impact strength, wide temperature range
2. High transparency and free dyeing
3. H.D.T. High
4. Good fatigue resistance
5. Good weather resistance
6. Excellent electrical characteristics
7. Comply with hygiene and safety standards
8. Low forming shrinkage and good dimensional stability.

Disadvantages: Poor design of formed products is prone to internal stress problems.

ABS+PC material and characteristics

PC+ABS material is actually made of PC plastic+ABS plastic, which has high gloss and good toughness, but its heat resistance is not as good as that of pure PC plastic.

The PD charger actually is a transformer, which converts the household 220V alternating current into suitable low-voltage direct current. During the conversion process, about 30% of the electric energy will be consumed and dissipated through the air in the form of heat energy. Therefore, when the mobile phone is charging, the charger will generate a lot of heat energy. In order to protect the user’s charging safety, we choose pure PC flame retardant material that is more resistant to high temperature.
