1. PET plastic is a milky white or yellow highly crystalline high polymer. The suitcases made from it are not only smooth and very shiny, but also have good physical machinery in a wide temperature range. performance. PET has good electrical insulation, and can be used for a long time at a temperature of up to 120 degrees Celsius. It has good electrical properties even at high temperatures and high frequencies, but it has poor corona and can have very good creep resistance, Fatigue resistance, friction resistance, and dimensional stability.
2. Compared with the trolley case made of pure PC, ABS + PC synthetic material is cheaper, and the surface of the produced trolley case is better, and it is easy to paint and color. It can also spray metal, Processed by electroplating and hot pressing, the appearance pattern is exquisite. Although this synthetic material has better impact resistance than PC, its texture and rigidity are lower than that of PC.
3. The leather materials used in making luggage are generally leather and artificial leather, and the leather is generally derived from animal fur, such as cowhide, pigskin, and sheepskin. Compared with artificial leather, leather cortex has the characteristics of comfortable, fullness and softness, and the surface of the leather has good water absorption. On the contrary, Shangxin trolley case thinks that artificial leather does not have this feature, but has better water resistance.
