How to choose an Apple phone case
1. PP material: the lightest and thinnest
First, let’s take a look at the PP raw materials. Chemical name: polypropylene. Features: low density and rigid strength. It is a good substitute for PC material. Polypropylene is a non-toxic, odorless, and tasteless milky white highly crystalline polymer. The outstanding performance is the resistance to bending fatigue and not easy to break. Many children’s bottles are made of PP. The PP protective case is characterized by its hardness and flexibility..
2. TPU material: soft and transparent
The properties of TPU material are relatively close to silica gel, which is a relatively soft material. However, it has the characteristics of full transparency, non-toxic environmental protection, and strong plasticity, so it quickly replaced silica gel. TPU is the abbreviation of Thermoplastic Urethane thermoplastic polyurethane elastomer. Compared with silicone protective sleeves, TPU sleeves are harder, more transparent, and have better elasticity and shock resistance than silicone. The representative product of TPU protective case, i-Softhin protective case of KFA2. This protective case uses a fully transparent design with a thickness of 0.55mm and an ultra-thin texture. Because it is made of TPU material, this protective case will not deform even if you squeeze it at will. It has super flexibility and has the ultimate shock absorption effect, which effectively protects your iPhone 6 from scratches and bumps.
