Cell Phone Shell-Liquid Silicone, TPU, PC Cell Phone Shell Analysis
Sep 23, 2018

With the development of smart phones, mobile phone shells are important auxiliary materials. The common ones are silicone cell phone shells, TPU cell phone shells, and PC cell phone shells. So liquid silica gel, TPU, PC phone shell sleeve which is good? Cell phone shell manufacturers-Cosme from the liquid silica gel, PC, TPU three materials to introduce one by one.

Liquid Silicon gel mobile phone sleeve: Liquid Silicon gel mobile phone sleeve is a typical application of Silicon gel protective sleeve. Consumer groups are numerous, and we are all familiar with a type of protective cover. Its texture is soft between Shaw's hardness 35-80A, its feel is slightly slippery, and its popular market has been for many years. Silicon rubber, commonly known as silica gel, is a highly active adsorption material and is an amorphous substance. Insoluble in water and solvents, non-toxic and odorless, stable chemical properties.

Advantages: cheap, high adsorption performance, good buffer performance, not easy to wear, protection is more comprehensive.

TPU phone sleeve: TPU elastomer is a material between silicone rubber and PC plastic. It is resistant to oil, water, mold, and TPU products have outstanding bearing capacity, impact resistance, and shock absorption. TPU is a modified plastic product. The product is made by an injection molding process. After the TPU raw material is heated and melted, the product is made of a barrel into a plastic mold.

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

PC cell phone shell: PC material is actually one of the engineering plastics we call it. The scientific name is polycarbonate, a polymer containing carbonated groups in the molecular chain. According to the structure of the Ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. As a widely used material in the world, PC has its own characteristics, advantages and disadvantages. PC is a kind of amorphous thermoplastic resin with excellent comprehensive performance, with excellent electrical insulation, elongation, dimensional stability, and chemical corrosion resistance., High strength, heat resistance and cold resistance; It also has the advantages of self-extinguishing, flame retardant, non-toxic, and colouring. The shadow of PC plastics can be seen in all corners of your life. The characteristics of large-scale industrial production and easy processing also make its price relatively favorable.

Advantages: good light permeability, strong hardness, anti-fall, light and thin, strength and toughness

Hardness: PC, TPU, silica gel hardened in turn;

Appearance: TPU transparency, PC transparency is relatively good, silica gel is relatively foggy;

Price: PC is cheap, TPU is second, silica gel is relatively expensive;

Silicone PC, TPU Composite Cell Phone Shell

Because all kinds of materials have their own excellent characteristics, the future silicone PC and TPU composite mobile phone shell sleeve has become a field of concern. Silicon gel is wrapped in a large area of PC shells, and TPU materials are used in the bottom corners and weak volume keys that are often stripped. Super velvet fabric is used to protect the rear shell of the phone.
