The Difference between Silicone Gel, TPU and PC

Silicone material

Silica gel (also known as silica): silicone rubber is a kind of highly active adsorption material, which belongs to amorphous material, and its chemical formula is msio2 · nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable in chemical properties, no reaction with any substance except strong base and hydrofluoric acid. Different types of silica gel have different microporous structures due to different manufacturing methods.

The chemical composition and physical structure of silica gel determine that it has many characteristics that can not be replaced by other similar materials: high adsorption performance, good thermal stability, chemical stability, high mechanical strength, etc. Silica gel can be divided into: macroporous silica gel, macroporous silica gel, B-type silica gel and microporous silica gel according to its pore size.

At present, the silica gel sleeve can be divided into two kinds, one is organic silica gel and the other is inorganic silica gel. At present, the digital products on the market are basically organic silica gel. It has the characteristics of high temperature resistance, good weather resistance (not afraid of ultraviolet or ozone decomposition), good insulation, stable material and so on.

Advantages: low price, high adsorption performance, good buffer performance, not easy to wear, comprehensive protection.

TPU material

TPU is the main material for making clear water jacket. It is the abbreviation of thermoplastic urethane thermoplastic polyurethane elastomer. The so-called elastomer refers to the polymer material with glass transition temperature lower than room temperature, elongation at break > 50%, and good recovery after external force removal. Polyurethane elastomer is a special kind of elastomer, which has a wide range of hardness and performance, so polyurethane elastomer is a kind of polymer material between rubber and plastic. It can be plasticized by heating and has little or no cross-linking in chemical structure. Its molecule is basically linear, but there is a certain physical cross-linking. This type of polyurethane is called TPU.

Advantages: high wear resistance, high strength, oil resistance, good flexibility

PC material

PC is the abbreviation of polycarbonate. Polycarbonate English is polycarbonate, which is called PC engineering plastics for short. PC material is actually one of the engineering plastics that we call, as a kind of engineering plastics in the world Widely used materials, 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, chemical corrosion resistance, high strength, heat resistance and cold resistance; It also has the advantages of self extinguishing, flame-retardant, non-toxic and colorable. You can see the shadow of PC plastic in every corner of your life. Its large-scale industrial production and easy processing make its price extremely low.

Advantages: good light transmittance, strong hardness, falling resistance, good toughness.
