At the same time that mobile phones are becoming more and more important to humans, mobile phone cases have also become a must-have item. After all, protection for mobile phones can’t be less! Otherwise, accidentally throwing the phone and leaving an ugly scar on the case However, it will directly affect the normal use of the mobile phone, and it may even be necessary to repurchase another one. Therefore, it is very important to carefully choose a mobile phone case.
When it comes to buying a mobile phone case, you can’t get around the material of the phone case. In fact, the small mobile phone case is actually quite famous! ABS, PMMA …. Many English letters and professional terms make people dizzy. Today, Xiaobian will make a popular science for everyone!
ABS
Speaking of such high technical terms as ABS, many small partners may not understand. Actually, ABS is a material that can be seen everywhere in our lives. In addition to being used as a mobile phone case, it is also widely used in various digital product cases and daily necessities.
Basically, ABS is a resin plastic with a wide range of uses. It has relatively strong abrasion resistance and can effectively prevent mobile phone wear. However, its poor toughness will cause the casing to break when the mobile phone is dropped, and thus it cannot effectively protect the mobile phone.
PMMA
PMMA, also known as polymethyl methacrylate, is also known as plexiglass. After hearing this, you may want to ask, I have never seen a glass phone case, Xiaobian, do n’t fool around! In fact, it’s not that the editor made a blind statement that plexiglass is not glass but a kind of plastic. In addition to wear resistance and corrosion resistance, it also has the characteristics of beautiful appearance and high surface gloss, which can be regarded as the best choice for high-value mobile phone cases. However, it has a fatal shortcoming that it is all in one, and that is-expensive!
TPU
TPU is a common soft shell. Unlike the above two plastics, TPU is a rubber material, which is generally recycled from environmentally friendly materials. Because of its soft and elastic characteristics, TPU is very protective. Not only can ordinary small scratches prevent it, but also it has no fear in the face of extremely destructive impact. It is an ideal material for mobile phone cases. The only disadvantage is that it is not resistant to dirt. In natural environments, TPU easily oxidizes and yellows, which affects appearance.
