The material and raw materials of mobile phone case are mainly divided into soft shell and hard shell.
The main materials of soft shell are silica gel soft shell and transparent soft shell. Hard shell materials mainly include pp shell, pc shell, glass shell, leather case and so on.
Second, the advantages and disadvantages of soft shell:
1, silicone soft shell:
Advantages: Silicone material is environmentally friendly and healthy, soft and skin-friendly, pollution-free, nonpoisonous and tasteless, good in elasticity, difficult to deform after processing and molding, resistant to falling A+ and good in hand feel.
Disadvantages: easy to get dusty. Silicone shell mostly adopts hard PC and flocking design, which leads to poor heat dissipation performance and a certain thickness of silicone shell.
Users: suitable for office workers who don't play game files (or take off their shells when playing games), Amy's series.
2, transparent soft shell:
Advantages: Most of them are transparent, black or painted with tpu. Because it is made of rubber, its protective performance is the first, and it is impact-resistant, soft and thermoplastic, and can be sprayed into various color patterns, which is also the cheapest in the mobile phone shell industry.
Feel good, each model can ensure obedient and accurate and comfortable buttons, and the most cost-effective. There is basically no color difference in the design of mobile phone case. For example, if you make a light-colored picture of a mobile phone case, you'd better recommend a transparent soft case.
Disadvantages: it is easy to yellow, and it needs to be replaced every month.
After a period of use, the shell will change color, deform and be fragile due to the corrosion of light, oxygen, water vapor, oil stains, sweat stains on hands and other substances.
Third, the advantages and disadvantages of hard shell:
1, pp shell
Advantages: it can effectively prevent hand sweat, heat dissipation is the best in the mobile phone case, and it can be ultra-thin. In order to pursue ultra-thin mobile phone case, major manufacturers will use pp material instead of pc material.
Disadvantages: it is not resistant to falling, and the base plate of pp shell is too fragile to bear any impact.
2, pc shell
Advantages: The thin PC case is rich in colors, which can provide comfortable touch and fashionable visual enjoyment. The heat dissipation performance is second only to pp shell, and the scratch-proof effect is good.
Disadvantages: If you drop your phone frequently, you will fall into the corner, and your protection performance is slightly lower.
3. Glass shell
Advantages: Wear resistance and scratch resistance. At present, the metal mobile phone cases on the market are all made of aluminum-magnesium alloy, which has high deformation resistance and fracture resistance, so it has ideal protective performance. Good gloss, various colors, not as broken as glass, with a certain weight, high temperature resistance and corrosion resistance, and feel very similar to glass shell. The pattern is colorful, durable, not easy to fade, fashionable and beautiful.
Disadvantages: not ultra-thin. However, the metal mobile phone case is relatively heavy and has poor portability, which causes certain interference to the signal.
4. holster
Advantages: Business series, the leather has the feel and style of leather, which is actually the same as the silicone shell, except that the outer silicone layer is replaced by leather, which has a good feel. The cortex is delicate and high-end.
Disadvantages: not resistant to high temperature.
