There are many kinds of materials for the mobile phone protective case. At present, the most common materials in the protective case market are silica gel, TPU, PC materials. Then we can not help asking, what are the differences between PU, silica gel and PC three material?
Silicone protective cover can be said to be the most familiar with consumers, but also the largest number of protective cover types. At present, there are two kinds of silica gel covers, one is organic silica gel, the other is inorganic silica gel. At present, the commercially available digital products silicone gel basically belongs to organic silica gel. It has the characteristics of high temperature resistance, weather resistance (not afraid of ultraviolet or ozone decomposition), good insulation, stable material and so on.
Silica gel sleeve also has a good feel, part of the button stiff mobile phone, put on the silicone gel sleeve will also be improved. It can also absorb some bump impact on mobile phones, to a certain extent, to reduce the harm to mobile phones. In addition, the silicone sleeve also has good waterproof performance, which has become one of its biggest selling points. Silica gel sheath itself has a slight viscosity, after a period of use will adsorb a large amount of dust on the phone, in the long run, but not conducive to the beauty of the phone, contrary to the original intention of protecting the phone.
TPU is a kind of elastomer between rubber and plastics. It is resistant to oil, water and mold. The load-bearing capacity, impact resistance and shock absorption of TPU products are outstanding.
From the feel, the hardness of TPU is generally harder than that of silica gel, the elasticity of hand pinch is stronger, and the elasticity of silica gel is slightly worse. From the outside, TPU can be made very transparent, not silica gel, the most transparent are very hazy like thick fog that feeling. It is precisely because of the transparent feeling of TPU that it is now more popular with users. Moreover, TPU products are also available at a high grade, with strong selectivity and more pattern changes than silicone.
PC is the abbreviation of polycarbonate, polycarbonate English is Polycarbonate, PC engineering plastics, PC material is actually what we call one of the engineering plastics. PC protective case is different from silica gel and TPU protective case, it is hard, PC plastic toughness is very good, transparency is also very good, pure PC plastic has pure transparent, transparent black transparent blue and other colors, are very good.
