Differences in TPU, silicone, PC phone casePublished time:2019-10-28 Reading times:7
There are many kinds of materials for mobile phone protective cases. At present, the most common products in the protective shell market are silicone, TPU and PC materials. Then we can't help but ask, what are the differences between PU, silicone and PC? Which material is better for PU, silicone, and PC?
1, silicone material:
The silicone case is the most familiar to consumers and the most used type of 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 goods to the well-crafted individual brand, the market share has always been leading.
The chemical composition and physical structure of silica gel determine that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel is classified according to its pore size: macroporous silica gel, coarse pore silica gel, B-type silica gel, and fine pore silica gel.
Currently known silicone sleeves are mainly divided into two types, one is organic silica gel and the other is inorganic silica gel. At present, the commercially available digital product silicone sleeve is basically organic silica gel. It has the characteristics of high temperature resistance, good resistance to weathering (not afraid of ultraviolet rays or ozone decomposition), good insulation and stable materials.
Advantages: low price, high adsorption performance, good cushioning performance, not easy to wear, and comprehensive protection.
Disadvantages: the texture is thicker, the style is less, it is easy to greasy, and the fit of the fuselage is slightly worse. At the same time, the material is slightly worse and it is easy to get ash and ash.
The silicone sleeve also has a good hand feeling, and some of the buttons are hard and the mobile phone will be improved after the silicone sleeve is put on. It can also absorb the impact of some bumps on the mobile phone, which can reduce the damage to the mobile phone to a certain extent. In addition, the silicone sleeve also has a good waterproof performance, which has become one of its biggest selling points. The silicone sleeve itself has a slight viscosity. After using it for a period of time, it will absorb a lot of dust on the mobile phone. In the long run, it is not conducive to the beauty of the mobile phone, and runs counter to the original intention of protecting the mobile phone.
2, TPU material
TPU elastomer is a kind of material between rubber and plastic. It is resistant to oil, water and mold. The load-bearing capacity, impact resistance and shock absorption performance of TPU products are outstanding. TPU belongs to the plastic category. The product is made by the injection molding process. After melting a plastic rice of a grain, it is injected into a plastic mold with a barrel to make a product.
Advantages: high wear resistance, high strength, outstanding cold resistance, oil resistance, water resistance, mildew resistance, good flexibility
Disadvantages: easy to deform, easy to yellow
From the feel of the hand, the hardness of the general TPU will be harder than that of the silica gel, and the elasticity of the hand is strong, and the elasticity of the silica gel is slightly worse. From the outside, the TPU can be made very transparent. Silicone is not allowed. The most transparent one is very embarrassing like a thick fog. It is because of this transparent feeling of TPU that it is now more popular with users. Moreover, the TPU products are still a lot of high-grade, and the selectivity is relatively strong, and the pattern changes more than the silica gel.
3, PC material
PC is a kind of comprehensive performance material with excellent electrical insulation, elongation, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance; also self-extinguishing, flame retardant, no Poison, coloring and other advantages.
Advantages: good transparency, strong hardness, resistance to falling, light and thin, good strength and toughness
Disadvantages: not scratch-resistant, not resistant to strong acid, not resistant to alkali, not resistant to ultraviolet rays
PC material protective shell is different from silicone and TPU protective shell, it is hard, PC plastic has good toughness and good transparency. Pure PC plastic has pure transparent, transparent black transparent blue and other colors. Very good.
