According to China Brand Network, the hard-shell mobile phone case is as follows:

1, PP hard shell: PP hard shell can be very thin, so it will not affect the heat dissipation performance of the mobile phone too much, and because of the material characteristics, it can prevent the damage of hand sweat to the mobile phone case. However, the impact resistance and fall resistance of pp shell are very poor, so it can only be used to "look" and has little effect on protecting mobile phones.

2, PC hard shell: the mobile phone case made of PC is also relatively thin, which does not hinder the heat dissipation performance and feels good. However, like PP hard shell, the anti-fall performance is poor.
