What is the pearl in the palm of contemporary times?

Of course it‘s a phone!

In daily life, a mobile phone can be said to be an indispensable part of the phone. In addition to sleeping time, it must always be necessary. If you don‘t look at your phone every few minutes, you will feel uncomfortable. Without your phone, you will feel inexplicable anxiety, confusion, loss, and even a little confused

I have a mobile phone in my hand. But with the bare machine in hand, it seems to lack some sense of security. I‘m either afraid it might scratch or fall, afraid it might get a little injured. So, the first reaction most people have when they get a phone is to buy a phone case first!

At present, the most common phone cases are mainly divided into three types: liquid silicone, TPU material, and PC material, with metal material, leather material, and carbon fiber material becoming increasingly rare. A good phone case not only protects the phone, but also decorates the phone and beautifies it.

Next, let‘s learn about the performance of three types of phone cases:

01

TPU material

Features: The texture is between liquid silicone and PC, with super strong wear resistance, excellent ozone resistance, good shock absorption effect, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance, and environmental resistance. It can be printed, with good hand feel and aesthetics. It is transparent and not easy to scratch, but the hand feel is relatively hard and easy to turn yellow;

02

PC materials

Features: Hard texture, good strength and toughness, strong impact resistance, easy dyeing, relatively light and thin, not affected by temperature, good creep resistance, stable size, high transparency, but the texture is the hardest and easy to scratch, transparent PC material is easy to turn yellow;

03

Liquid silicone

Features: Soft texture, good hand feel, good tear resistance, rebound resistance, yellowing resistance, thermal stability, water resistance, heat aging resistance, excellent weather resistance, moderate viscosity, easy processing, good breathability, good shock absorption effect, but opaque;

Among these materials, the performance of different materials varies. TPU and PC materials have transparent properties, especially TPU material, which is the most popular among consumers due to its moderate comprehensive performance, difficulty in scratching, and affordable price. Because TPU turns yellow, a large number of TPU phone cases are discarded every year. Topcentralhas modified these discarded TPU materials to become recycled materials.
