PC: Polycarbonate, it is a colorless and transparent amorphous thermoplastic material. Unlike silicone protective case and TPU protective, PC case is hard, PC plastic toughness is pretty good, light transmission is pretty impressed, there are pure transparent PC hard case, transparent black PC hard case and transparent blue PC hard case and others available.
Pros: good transmittance, hardness, resistance to fall, light Disadvantages:dissatisfied scratch resistance PC hard case has three processes1.vacuum plating process: electroplate, then carve some of the patterns on the PC housing, UV varnish.2.PC spraying:spray rubber oil, or the transparent red, transparent blue, transparent yellow, etc.
Those spraying a layer of primer on the transparent PC case and laser engraving pattern and spraying a rubber paint are slightly better.
PC thermal transfer process: transfer patterns on the PC housing , and then spray UV varnish or soft touch rubber oil.Those spraying rubber oil are better.
The disadvantage is that the surface does not resistant scratch. TPU is a thermoplastic polyurethane elastomer rubber, which can be softened at a certain temperature and can keep itself unchanged at room temperature .
Most of the TPU plays a key role in supporting the shoe.The toughness and elasticity of TPU protective case significantly beyond the traditional silicone case, it is know as translucent matte texture. TPU case belongs to the plastic case, which is molded by injection process, that means it is made by plastic injection mold where the plastic pellets heated and melted is inserted by a barrel.
Advantages of TPU case: transparent, color-rich, anti-fall, feel good, easy to take hold, difficult to wear.
Disadvantages of TPU case: prone to be yellow, or even sticky on your hands.
TPU case is generally harder with more optional style than silicone case, flexible and strong over than silicone. TPU can be completely transparent. TPU case is capacity of withstanding the extremely low temperatures, it is still able to maintain good elasticity even at minus 35 degree, it can freely keep flexibility and other physical properties to fully protect the tablet from external shocks.
Silicone case is usually made of rubber, which is soft and flexible and clear and transparent and often used to protect digital products to prevent accidental falls or worn. The price is pretty cheap.
How to make silicon caseBy adopting a vulcanization molding as forming process,put a piece of silicone raw materials cut and placed inside the silicone mold which is the upper and lower mold , heat pressurized and make products.
Pros: good protection, anti-fall, feel good, easy to take on and off,difficult to wear, cheap. Disadvantages: less style, easy greasy, not suitable for use in the summer, easy to deform How to choose high quality silicone iPad mini tablet silicon caseSmell,no pungent smell, or even have a scent.
