1、Plastic
Mainly belongs to the rubber class, the finished product process with the vulcanization molding. Are a piece of silicone into the mold, and then heated and pressed into the product, silicone is generally imported, bad silicone edges will be particularly obvious, affecting the beauty.
2、pc material
pc scientific name polycarbonate, is a thermoplastic engineering plastic. pc material toughness and luster is particularly good, the product can be made very thin, iPhone cases can reach the thinnest 0.5mm, pure pc material color.

There are several better for example.
1, silicone shell
Silicone shell is the most familiar type of cell phone case. It has a soft texture, slightly slippery feel, popular market has been many years. From the development of crude stall goods to well-made personality brand, market share has always remained ahead. Because of its excellent cost performance, silicone cases also became popular and favored by many people when MP3 and iPod were hot later. There are two kinds of silicone cases, one is organic silicone and the other is inorganic silicone. The silicone cases for cell phones on the market now basically belong to the former. There are many advantages of organic silicone, such as high temperature resistance, trespassing resistance (not afraid of UV or ozone decomposition), good insulation, and stable material (will not change with animal body). Besides, people choose silicone case because of its good handfeel: some of the phones with hard keyboards will be improved after putting on silicone case. And it can absorb the impact brought by some knocks on the phone, thus reducing the damage to the phone. In addition, the silicone case is better waterproof, which has also become its biggest selling point. Although the advantages of silicone cases, and the price is low. But there are still shortcomings, due to poor breathability, long-term wear will lead to the accumulation of heat in the phone body. Especially some of the heat is quite high smart phones, it is not recommended that users use. Moreover, the silicone case itself has a slight stickiness, after a period of time will gather and absorb a lot of dust on the phone, in the long run, but is not conducive to the beauty of the phone, and the original purpose of protecting the phone goes against. In addition to the above considerations, the purchase of silicone cases for cell phones is also worth paying attention to one or two. Nowadays, there are a wide range of silicone shells, stalls, supermarkets, cell phone market everywhere. But by no means buy the right phone model everything is fine, the price is exceptionally cheap silicone shells are often of poor quality, either not on the set, or the position is not symmetrical. Good quality is really good, effective protection is the king. Most of the current regular silicone shells are priced at just over a dozen dollars, there is no need to be cheap and lose a lot because of the small.
2, crystal shell
Silicone shells and holsters have their own merits and shortcomings, in order to achieve comprehensive protection, another kind of cell phone protective cover came into being. This is the crystal case favored by women. It is made of plexiglass, thick and sturdy appearance, the shell body crystal clear. Not only can effectively protect the phone, but also do not affect the appearance, can be described as a deep silicone cover and leather cover. However, the purchase of crystal shell is also a test of vision. Although the cost of crystal shell is not high, the process is also relatively simple, but some businesses in order to earn higher profits, in the workmanship and materials or can save on saving. First of all, the appearance of the crystal shell depends largely on the abrasive, abrasive good, the quality of the crystal shell out of the pick hard. The size of the crystal case made by irregular grinding tools will be deviated, and some even can not fill the phone; secondly, the thickness of the crystal case requirements are relatively strict. Too thin or bad hardness, it is easy to break. If it is too thick, it will affect the operation. In addition, since it is called crystal, crystal shell shell must be translucent, however, some crystal shells are gray or even yellow, which is another problem of cutting corners. Crystal case of course also has disadvantages, because it has a certain hardness with the phone, so the two will inevitably produce friction, especially the corners of the phone, usually these four parts of the phone are the most serious wear. Shopping needs to be careful, don't be afraid to compare goods. Crystal case price is not expensive, at best, a few dozen dollars, the price is still very affordable.
3, TPU plastic
Put the second said because TPU is also soft, and silicone like soft rubber products, many people are confused about the difference between silicone and TPU, and even some Taobao sellers are confused, the soft are said to be silicone. TPU belongs to the plastic class, the product is made by injection molding process, is a grain of plastic rice melted at temperature, with a gun barrel shot into the plastic mold and made products.
