Silicone, Tpu, Pc, Mobile Phone Case Big Competition

1: Silicone

Silica gel is a kind of highly active adsorption material, belongs to an amorphous substance, its chemical formula is mSiO2·nH2O; in addition to strong alkali, hydrofluoric acid does not react with any substance, insoluble in water and any solvent, non-toxic tasteless, stable chemical properties. Silicone has high transparency.

Advantages: easy to use, dustproof, anti-dip fingerprint, easy to handle; soft and hard moderate, mobile phone silicone cover will have a certain degree of softness to protect the mobile phone; there are many kinds of mobile phone silicone covers, there are many different specifications of the pattern, you can change different mobile phone silicone covers every day or regularly to enrich life, and it is waterproof.

2. TPU

Thermoplastic polyurethane elastomer rubber. Mainly divided into polyester type and polyether type, in daily necessities, sports goods, toys, decorative materials and other fields are widely used, halogen-free flame retardant TPU can also replace soft PVC to meet the environmental protection requirements in more and more fields. Viewed from the outside, Tpus can be made very transparent.

Advantages: Wide hardness range, wear resistance, oil resistance, transparent, good elasticity.

Disadvantages: Variability, yellowing.

3. PC

PC is the abbreviation of polycarbonate, referred to as PC engineering plastics, PC material is actually one of the engineering plastics we say, as a material widely used in the world, PC has its own characteristics and advantages and disadvantages, PC is a kind of excellent comprehensive performance of amorphous thermoplastic resin, in every corner of your life can see the shadow of PC plastic, Large-scale industrial production and easy processing also make it extremely cheap. High transparency. PC material protection shell transmittance is also very good. However, the high transparency of the PC protective shell production process requirements are relatively high, translucent PC shell is relatively common.

Advantages: excellent electrical insulation, extensibility, dimensional stability and chemical corrosion resistance, high strength, heat resistance and cold resistance, but also has self-extinguishing, flame retardant, non-toxic, coloring and other advantages, low price.

Disadvantages: scratch resistance, strong acid resistance, strong alkali resistance, UV resistance
