Material classification of mobile phone shell

No matter in mold design, injection molding process or coating performance, there has been a great breakthrough, using Pc material as the mobile phone shell.

The proportion of shells is rising. It is estimated that the proportion of Pc materials used in mobile phone casings has exceeded 50%. And now there is a mobile phone case.

Because of the filming treatment, the appearance has been greatly improved. Plastics can be divided into ordinary grade, temperature-resistant grade, impact-resistant grade, flame-retardant grade and electroplating grade according to their uses.

1PC polycarbonate. Performance characteristics of materials:

① High strength, tensile strength of 69MPa and bending strength of 96MPa.

(2) High temperature resistance, long-term use can withstand the temperature environment of 65438 030 degrees Celsius.

③ Good transparency and no toxicity.

④ The color matching and surface coating of raw materials are not as good as ABS.

(5) PC should choose a brand with high liquidity. Suitable for clamshell machines and mobile phones used in harsh environments.

2 ABS (acrylonitrile butadiene styrene * * *) material performance characteristics:

① Low strength, with tensile strength of 43MPa and bending strength of 79MPa.

(2) Not resistant to temperature, and the long-term use temperature shall not be higher than 60 degrees Celsius.

③ Good fluidity, coloring, surface spraying and electroplating performance.

The synthetic materials of 3 Pc and ABs take the characteristics of the former two.

It has excellent formability, good fluidity and high strength (tensile strength 56MPa, bending strength 86MPa). The Pc+ABS material is mainly used for straight board machines and general clamshell machines that require high appearance and color, but have no special requirements for the environment.
