How to select to phone case that is fit for you

We don’t pay the insurance for our phone, but we will add some extra protection for it，a phone case is one of the protection for your phone .So what case should we select for our smartphone ?

When it comes to buying the case for our phone, we have met some problems more or less, such as “It scratches very easy” "The buttons are way to stiff when using this cases" "The color is beautiful and it’s easy to pop on but the material is NOT durable.”

Actually, most of these problems are related to the material that the phone case is made from, every material has its own advantage and disadvantage,after we know the performance of the material, we can choose a better case that is fit for you.

Silicone phone case:

Silicone phone case is a typical application of silicone protective cover. It’s softness is  between 35-80A Shore hardness and a slightly slippery feel. It has been popular in the market for many years.

Silicone rubber, commonly known as silica gel, is a highly active adsorption material, which is an amorphous substance. It is not easy to dissolve water and solvents, is non-toxic and tasteless, and has stable chemical properties.

Advantages: low price, high adsorption performance, good cushioning performance, wear-resisting, comprehensive protection.

Disadvantages: thick texture, few styles, easy to be greasy, slightly poorer fit with the chassis, and poorer materials are also easy to stain and enter dust.

TPU phone case

TPU is a material that elasticity between silicone and PC. It is resistant to oil, water and mould. TPU products have outstanding bearing capacity, impact resistance and shock absorption performance.

TPU is a modified plastic, the product is made by injection molding process, that is, after the pellets of TPU raw materials are heated and melted, they are injected into the plastic mold with a barrel to make the product.

Advantages: high transparency, high strength, wear resistance (cold, oil, water, mold), good flexibility

disadvantages: it is easy to deform and get yellow;

 PC phone case

PC material is actually one of the engineering plastics we call. The scientific name is polycarbonate. It is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic and fatty Group-aromatic and many other types. As a material widely used around the world, PC is an amorphous thermoplastic resin with excellent comprehensive properties, with excellent electrical insulation, extensibility, dimensional stability and chemical resistance Corrosion, high strength, heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable, etc., you can see the shadow of PC plastic in every corner of your life, large-scale industrial production And easy processing characteristics also make the price extremely low.

Advantages: Good light transmittance, strong hardness, drop resistance, light and thin, good strength and toughness

Disadvantages: Not resistant to scratches, strong acids, strong alkalis, and ultraviolet rays.

Hybrid case (Liquid silicone and PC, TPU composite mobile phone case)

Since various materials have their own relatively excellent characteristics, the future silicone PC, TPU composite mobile phone case will become an area of ​​concern for everyone. There is one of the IPHONE8 mobile phone protective cases, and the silicone-covered PC and TPU composite mobile phone cases are super fit. Made of fiber flannel. Silicone covers a large area of ​​the PC case, and uses TPU material at the bottom corners that are often peeled off and where the volume buttons are weak. Super fiber flannel is used to protect the back case of the phone. It has the characteristics of firm bonding and convenient use. Synthesize the characteristics of each material, give play to the advantages of each material and avoid material defects. It is also a development direction for mobile phone cases and mobile phone sets in the future.

Wooden mobile phone covers:

The manufacturing cost will be higher, and there are fewer mobile phone covers on the market, and they are more expensive to sell. Featuring Smooth hand feel and strong protection, wear resistant. But It's not easy to disassemble.

Metal phone case

Metal phone case: In fact, metal phone case will be more resistant to fall and off stronger protection, but it has a certain influence on the signal and the weight is much heavier than plastic.

Leather mobile phone case:  

Featured with smooth hand feel , great grip, skin-friendly and the luxury appearance,.But slightly expensive, some of the poor quality will peel off. When choose the leather phone case, the premium leather is important.
