What is the material of the silicone protective cover

The silicone protective cover is made of silicone, namely Polycarbonate. 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 development of shoddy stalls to well-made individual brands, the market share has always been in the lead. Because of its excellent cost performance, silicone sleeves became popular when MP3 and iPod were popular later, and they were favored by many people. There are two types of silicone sleeves, one is organic silica gel and the other is inorganic silica gel. Silicone cases for mobile phones on the market now basically belong to the former. Organic silica gel has many advantages, such as high temperature resistance, good weather resistance (not afraid of ultraviolet rays or ozone decomposition), good insulation, and stable material (will not change with animal bodies). In addition, people choose silicone sleeves because of its good feel: some mobile phones with stiff keyboards will improve after putting on the silicone sleeve. And it can absorb the impact of some bumps on the mobile phone, thereby reducing the damage to the mobile phone. In addition, the waterproof performance of the silicone case is better, which has become its biggest selling point. Although the silicone sleeve 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 a high calorific value, it is not recommended for users to use them. 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 precautions, the purchase of mobile phone silicone sleeves is also worth paying attention to. Nowadays, there are a dazzling array of silicone sleeves, which can be seen everywhere on street stalls, shopping malls, supermarkets, and mobile phone markets. But it is not that everything will be fine if you buy the right phone model. Silicone sleeves that are very cheap are often inferior in quality. Good quality is really good, and effective protection is king. At present, most of the regular silicone sleeves are sold for less than a dozen yuan.
