The PC case is a very popular case. It restores the original color of the phone case and has high permeability. The PC material has high strength, fatigue resistance, dimensional stability, and good heat dissipation. It is the most common material with good heat dissipation and excellent insulation performance, so Very practical as a mobile phone case. Many post-processing can be done, such as spraying, painting, leather case, 3D embossing and so on.
Silicone case is the most well-known type of mobile phone protective case. It has a soft texture and a slightly slippery feel, and has been popular in the market for many years. From the shoddy stalls to the well-made individual brands, the market share has always been in the lead. Because of its excellent price-performance ratio, silicone shells became popular when MP3 and iPod became popular and were favored by many people. There are two types of silica gel shells, one is organic silica gel and the other is inorganic silica gel. Silicone cases for mobile phones on the market basically belong to the former. Organic silica gel has many advantages, such as high temperature resistance, good weather resistance (not afraid of UV or ozone decomposition), good insulation, and stable material (will not change with animal bodies). In addition, people choose silicone shells because of its good feel: some phones with blunt keyboards will improve after putting on the silicone shell. And it can absorb the impact of some bumps on the phone, thereby reducing the damage to the phone.
In addition, the waterproof performance of the silicone shell is better, which has become its biggest selling point. Although the silicone shell has many advantages, and the price is also low. However, there are still shortcomings. Due to poor air permeability, long-term wearing will cause heat accumulation in the phone body. Especially for some smart phones with high calorific value, it is not recommended for users. Moreover, the silicone case itself is slightly sticky, and after a period of use, it will gather and absorb a large amount of dust on the phone. In the long run, it will not be conducive to the beauty of the phone, which runs counter to the original intention of protecting the phone. In addition to the above considerations, the purchase of mobile phone silicone shells is also worth paying attention to.
