Which material is better for the trolley case pp or pc?

Update:17 Mar 2021

Pp material trolley case
Pp material is polypropylene, which is one of the materials of the hard box. This material is translucent, so the color of the pp trolley box may be relatively single. The inside and outside of the box are the same color, but its crystallinity It is relatively high, so the surface of the trolley case made of pp material is stronger, which can effectively prevent scratches caused by bumps, and has good impact resistance and water resistance.

Pc material trolley case
Pc is the abbreviation of polycarbonate, and it is also one of the materials of the hard case. This material is a transparent material, so the trolley case made of pc is bright and diversified. It has good heat resistance, cold resistance, and electrical insulation. It has good extensibility and is non-toxic and flame-retardant. It is a relatively common material in life. The trolley case made of pc has poor hardness, easy to scratch in appearance, good flexibility, and can rebound and not crack easily under heavy pressure.

What is the difference between Pp and pc
The wear resistance of Pp material is better, but the impact resistance and transparency are poor. The wear resistance of pc material is poor, but the impact resistance and transparency are strong, so the flexibility of the trolley case of pc material will be better than that of pp material. , PC material may appear slightly dented when impacted, but pp material may crack. The trolley case made of Pp material is heavier and lower in cost performance. The trolley case made of pc is in line with the current trend and has a higher cost performance.

Generally speaking, it is better to choose pc material, and the current pc material will be combined with abs material, so there is no need to worry about wear resistance. Of course, you can also choose the material that suits you according to your needs.
