What are the differences between PP, PVC, PC and ABS in the material of the trolley case?

1. Different properties: Pp is made of polypropylene, which is one of the materials of the hard box. This material is translucent. Pc is the abbreviation of polycarbonate, and it is also one of the materials of the hard case, which is a transparent material. ABS is the latest and more popular fashion trolley case material. The main feature of abs material is that it is lighter than other materials and the surface is more flexible. The trolley case made of PVC material is also the hard case.

2. Different characteristics: Pc has good heat resistance and cold resistance, electrical insulation and extensibility, and it is non-toxic and flame retardant. The crystallinity of Pp material 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. The trolley case made of PVC material has the characteristics of drop resistance, waterproof and impact resistance. The surface of abs material is more flexible and rigid.

3. Different wear resistance: Pp material has better wear resistance but poor impact resistance and transparency. PC material has poor wear resistance, but has strong impact resistance and transparency, so the trolley case made of pc is flexible. Performance will be better than pp material. The trolley case made of PVC material has poor wear resistance.
Precautions:

When buying a trolley case, do not only consider the style and brand, but also consider the material, size and style of the trolley case. If you can buy a 20-inch one, try not to buy a 24-inch one, because the smaller the box, the easier it is to carry. The price of the trolley case is also low. Of course, if you have a lot of luggage and cannot fit in a 20-inch box, you have to buy more boxes, such as 24-inch, 28-inch or even 32-inch. This varies from person to person.

It is best to buy a trolley case with an outer pocket, because when you go out, you need to take out your personal items such as tissues, water, umbrellas and so on from time to time. If the box does not have an outer bag, you must open the box every time you want to take something , This is very troublesome, so the trolley case is equipped with 1~2 outer pockets, and you can pull down the zipper with your hand to get your belongings.
