PRLog -- At present, mobile phones commonly used plastic material PC, ABS and PC + ABS three categories. Japanese mobile phone using PC + ABS, even with ABS do the cell phone case; South Korea a few in the machine manufacturer is the first pure PC material.GE originally did not recommend the use of the PC material from the cell phone case, and advocate the use of the PC + ABs materials, but the last couple of years have also introduced appropriateHop do the sub-machine outside Cardiff Pc materials such as EXLl414, and 141R, SP1210R.In recent years, the major mobile phone manufacturers to use the Pc material phone cover, even the ratio is gradually increased.On behalf of the main raw material supplier of GE, SAMSUNG, LG, and so on.Table 1 shows the general characteristics of the table for several materials:Other features of the material strength (tensile Mpa) Hardness (Rockwell R) temperature ()PC 69 120 130 non-toxic, light, low-temperature characteristics of a goodFeatures ABS 43 100 60 color, painting, plating, etc.56 110 60 the performance of the PC + ABS, center, processing, and mobility A few years ago, the A100, A100II mobile phone is the first to adopt the model of pure Pc materials.Such as HIP, mold and injection molding company is the first time using this material to do the cell phone case, therefore, have encountered a lot of trouble in terms of mold design, injection molding, spraying, and even the world-renowned several paint manufacturersalso failed to solve the adhesion of the coating, and finally had to direct from South Korea, near the mouth to the preparation of good paint.The past two years.Whether it is in terms of mold design, injection molding or coating performance has a significant breakthrough in mobile phone shell Pc materials on the rise.Preliminary estimate of the proportion of cell phone case with the Pc materials have more than 50%. Plastic by end-use can be divided into ordinary level, temperature level resistance, leveling, flame retardant grade, electroplating grade.1 PC PC generic polycarbonate.The performance characteristics of the material: ① high strength, tensile strength of 69MPa, anti-bending strength of 96MPa. ② high temperature, long-term use can withstand 130 degrees Celsius temperature environment. ② transparent, non-toxic. ④ raw materials, color and surface coating are not as good as the ABs. ⑤ the Pc should be selected high flow grades.Clamshell machine and mobile phone use in harsh environments.source:

(1) low intensity, the tensile strength of 43MPa, anti-bending strength of 79MPa. ② temperature, long-term use of a temperature not higher than 60 degrees Celsius. The the ③ mobility, coloring and surface coating and plating performance.3 PC + ABS, Synthetic material, Pc and ABs to take the front of both features, with excellent molding processability, good fluidity, high strength (tensile strength of 56MPa, anti-bending strength of 86MPa).Pc + ABS material is mainly used for straight machines and general appearance, color-flip machine without any special requirements on the environment.Table 2 Code of the materials used for the current machine is death and its manufacturer.Materials, GE Samsung samsung the LGPC GE141R (241R) 137 ° C of the general level.Models:

According to the appearance of the coating color selection: ① bright, multicolor, Xu loaded demanding, should be preferred Pc + ABs; ② need the appearance of doing electroplating, to be elected ABs. Clamshell machines and in harsh environments (such as low temperature, vibration, shock, etc.) should be used in the Pc material for use in rugged mobile phone, Candybar choice of materials: Available to PC and PC + ABS, PC + ABS preferred. Choose a PC, you should use the grades of the high mobility of Priority Samsung 1023M GE EXL1414, GEl41R, (241R). Note: The grades of the high mobility of the relative binding line, shrinking grain defects smaller, the general level is relatively high strength (because of the long molecular chains).
