Our daily use of mobile phone case materials are generally: silicone shell, TPU shell, PC shell, TPE shell, leather shell.
Silicone case
Silicone is divided into solid silicone and liquid silicone, mobile phone cases, many of the use of soft rubber materials to protect the case. Soft rubber material has better shock absorption performance, can play a better role in protecting mobile phones. Silicone is a common soft rubber mobile phone case material.
Silicone has excellent resilience, good low temperature resistance, comfortable and smooth touch, non-toxic and tasteless, top environmental protection, with good colour matching. Silicone protective case is the representative of middle and high-end mobile phone cases. Usually choose the material hardness 60~80A.
Advantages: silicone feel comfortable, with ductility and high elasticity, shockproof and anti-drop effect. Appearance effect is good can make simple modelling pattern.
Disadvantages: not resistant to dirt, easy to accumulate dust, poor heat dissipation, coating after polishing feel worse. Silicone’s shortcomings: thick texture, fewer styles, easy to grease, and body fit is slightly poor, long production and processing cycle, and difficult to recycle the material.
Our VNKing are able to offer a wide variety of wholesale phone cases, providing you with excellent service and stylish designs.
Second, TPU case
TPU can be said to be the most widely used mobile phone shell material, TPU has excellent resilience, no deformation, good low temperature resistance, non-toxic, tasteless, environmentally friendly materials, with good colour matching, excellent adhesion, low viscosity, good flex resistance, excellent abrasion resistance, high gloss, weathering performance and so on.
TPU material is relatively affordable, easy to produce and process, short processing cycle, secondary materials can be recycled and reuse. The common hardness range of 85~95 degrees, TPU mobile phone case is the shortcomings of the feel is relatively hard, easy to deformation, lack of silicone soft touch.
TPU made phone cases after a long time of use will have yellowing problems, and some of the surface of the white powder similar to frost, in the process of processing is very difficult to get out of the mould, low productivity, scrap rate is also the fatal shortcomings of TPU. Therefore, TPU is not the best choice for mobile phone shells, and it is not suitable to use TPU for high-end mobile phones.
Whether you are looking for customized wholesale phone cases or affordable bulk phone cases, we can provide you with a good, high quality solution quickly.
Third, acrylic shell
Advantages: not fragile, high transparency, weight is one half of the glass.
Disadvantages: acrylic surface hardness is not as good as glass, not scratch-resistant, the more you use the edge of the more hairy.
VNKing wholesales phone cases that combine durability and modern designs, making them ideal for resellers, cell phone cases wholesale distributors and import wholesalers.
Fourth, PC case
PC mobile phone case material good light transmission, hardness, drop resistance, thin and light, good strength and toughness.
PC material case is different from silicone and TPU protective shell, it is hard, PC plastic toughness is very good, good transmittance, pure PC plastic has pure transparent, transparent black transparent blue and other colours, are very good, but the appearance of easier to scratch.
Advantages: personalised full can be made in the surface of a variety of pattern production.
Disadvantages: not easy to disassemble, anti-drop function is not how, wear resistance is poor, easy to scratch, life is poor. Not scratch-resistant, not resistant to strong acid, not resistant to strong alkali, not resistant to ultraviolet rays.
We can offer a wide variety of wholesale phone cases, providing you with excellent service and stylish designs.
Fifth, TPE mobile phone case
Composite material mobile phone case is usually a soft plastic and hard plastic with, usually will be soft plastic TPE through the second injection (or two-colour injection) way to bond to the surface of hard plastic (such as, PC, PC + ABS, etc.). It makes the mobile phone case have the dual characteristics of rigidity and flexibility.
TPE material feels soft and smooth, better than silicone and TPU feel, good abrasion resistance, easy to colour, molding and demoulding is convenient, environmentally friendly and non-toxic, the human body will not produce allergic reactions!
This kind of mobile phone case is common in the border type mobile phone case and the whole structure type mobile phone case two kinds. For composite material cases, TPE with hardness of 65~70 degrees is usually used, and the bonding between TPE and PC or PC+ABS is an important consideration. In addition to TPE composite PC type mobile phone case, there are also TPE composite TPU mobile phone case, this kind of mobile phone case improves the TPU material elasticity is excellent, but the tactile sense of the shortcomings of the TPU material.
Whether you are looking for customized wholesale phone cases or affordable bulk phone cases, we can provide you with a good, high quality solution quickly.
Sixth, glass cases
Advantages: scratch and bend resistance is better hand feel is also better, with a sense of seniority.
Disadvantages: glass shell is fragile, and easy to get fingerprints.
In general, considering the feel of the choice of silicone, the pursuit of bare beauty and protection of choice of acrylic, the pursuit of advanced sense of choice of glass the pursuit of personality choice of PC shell, comprehensive performance TPU shell will be the best.
Our VNKing support customized wholesale phone cases or bulk phone cases, and looking for resellers, cell phone cases wholesale distributors and import wholesalers to cooperate.
