There are many kinds of materials for mobile phone protective cases. At present, the most common protective cases on the market are silicone, TPU, and PC materials. Then we can't help asking, what are the differences between PU, silicone and PC? Which material is better, PU, silicone or PC?
1. Silicone material:
Silicone protective sleeves are arguably the most familiar to consumers, and they are also the type of protective sleeves that are used most often. Its soft texture and slightly slippery feel have been on the popular market for many years. The market share has always maintained a leading position from the development of crudely spread goods to well-crafted personality brands.
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. According to the size of its pore size, silica gel is divided into: large-pore silica gel, coarse-pore silica gel, B-type silica gel, and fine-pore silica gel.
At present, there are mainly two types of silica gel sleeves, one is organic silica gel, and the other is inorganic silica gel. Silicone cases for digital products currently on the market are basically organic silicone. It has the characteristics of high temperature resistance, good weather resistance (not afraid of UV or ozone decomposition), good insulation, and stable materials.
Advantages: cheap price, high adsorption performance, good cushioning performance, not easy to wear, and comprehensive protection.
Disadvantages: thick texture, few styles, easy to greasy, and poor adhesion to the fuselage, while at the same time, the material with poor quality is also easy to stain and enter gray.
The silicone case also has a good feel. Some mobile phones with stiff keys will also improve after putting on the silicone case. It can also absorb the impact of some bumps on the phone, which can reduce the damage to the phone to a certain extent. In addition, the silicone case also has good waterproof performance, which has become one of its biggest selling points. The silicone sleeve itself is slightly sticky, and after a period of use, it will adsorb a large amount 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.
TPU material
TPU elastomer is a material between rubber and plastic, which is resistant to oil, water and mold. The bearing capacity, impact resistance and shock absorption of TPU products are outstanding. TPU belongs to the plastic type. The product is made by injection molding process. After melting a grain of plastic rice, it is injected into a plastic mold with a barrel to make a product.
Advantages: high abrasion resistance, high strength, outstanding cold resistance, oil resistance, water resistance, mold resistance, good flexibility
Disadvantages: easy to deform easily yellow
From the feel of the hand, the hardness of TPU is generally harder than that of silicone, and the elasticity of the pinch is strong, and the elasticity of silicone is slightly worse. Viewed from the outside, TPU can be made very transparent, silicone can't, the most transparent ones are very hazy like thick fog. It is precisely because of this transparent feeling of TPU that it is now more popular among users. In addition, there are still many high-end TPU products, which have strong selectivity and more pattern changes than silicone.
3.PC material
PC is a material with excellent comprehensive properties. It has excellent electrical insulation, elongation, dimensional stability, and chemical resistance, high strength, heat resistance, and cold resistance; it also has self-extinguishing, flame retardant, and Poisonous and colorable.
Advantages: good light transmission, strong hardness, anti-fall, light and thin, good strength and toughness
Disadvantages: not resistant to scratches, strong acids, alkalis, UV rays
PC protective case is different from silicone and TPU protective case. It is hard. PC plastic has good toughness and light transmittance. Pure PC plastic includes pure transparent, transparent black transparent blue and other colors. It's pretty good.
