With the development of smartphones, mobile phone cases are important auxiliary materials. The most common ones are silicone phone cases, TPU phone cases, and PC phone cases. So which is the best for silicone, TPU, and PC phone cases? Three materials, PC and TPU, are introduced to everyone. The new technology of CL-26AB glue in liquid silicone injection molding and PC and TPU composite mobile phone case is introduced.

Phone Case-Silicone, TPU, PC Case
Silicone mobile phone case:
Silicone mobile phone case is a typical application of silicone protective case. There are many consumer groups, and everyone is familiar with a type of protective cover. Its texture is soft between 35-80A Shore hardness, slightly slippery, and has been in the popular market for many years. Silicone rubber, commonly known as silica gel, is a highly active adsorbent material and is an amorphous substance. It is not easily soluble in water and solvents, non-toxic and tasteless, and has stable chemical properties.
Advantages: cheap price, high adsorption performance, good cushioning performance, not easy to wear, and comprehensive protection.
Disadvantages: thick texture, few styles, easy to be greasy, and poor fit with the body, at the same time, the silicone without the feel oil treatment is also easy to stain and enter
TPU mobile phone case:
TPU elastomer is a material between silicone rubber and PC plastic. It is resistant to oil, water and mold. TPU products have outstanding bearing capacity, impact resistance and shock absorption performance. TPU is a modified plastic. The product is made by the injection molding process. After the TPU raw material is heated and melted, it is injected into a plastic mold with a barrel to make a product.
Advantages: high transparency, high strength, wear resistance (cold, oil, water, mold), good flexibility
Inadequacy: easy to deform, easy to turn yellow;
PC Phone Case:
PC material is actually one of the engineering plastics we call. Its scientific name is polycarbonate, which is a high molecular polymer containing carbonate groups in its molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, and fatty. Families-Aromatic and other types. As a widely used material worldwide, PC has its own characteristics and advantages and disadvantages. PC is an amorphous thermoplastic resin with excellent comprehensive properties, which has excellent electrical insulation, elongation, dimensional stability, and chemical resistance. Corrosive, 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 also makes it extremely cheap.
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
Hardness: PC, TPU, and silica gel become harder in sequence;
Appearance: TPU transparency, PC transparency is relatively good, silicone is relatively foggy;
Price: PC is cheap, TPU is second, and silica gel is relatively expensive;
Silicone PC, TPU compound mobile phone case
Since various materials have their own excellent characteristics, silicone PC and TPU composite mobile phone cases will become a field of concern in the future. There is one of the IPHONE8 mobile phone protective cases. Silicone case PC and TPU composite mobile phone cases are super close Made of fiber flannel. Silicone wraps the PC case in a large area. TPU material is used in the corners that are often peeled off and the volume keys are weak. Super fiber fleece is used to protect the back case of the mobile phone. CL-26AB glue provides high quality bonding service for liquid silicone and PC, TPU injection molding. With strong adhesion, easy to use and other characteristics.
