PP material trolley suitcase

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

PC material Trolley Luggage

PC is the abbreviation of polycarbonate and one of the materials of hard box. This material is transparent, so the pull rod box made of PC is colorful and diverse. It has good heat resistance, cold resistance, electrical insulation and extensibility, and is non-toxic and flame retardant. It is a common material in life. The pull rod box made of PC has poor hardness and easy to scratch, Good flexibility. It can rebound under heavy pressure and is not easy to crack.

What's the difference between PP and PC

The wear resistance of PP material is good, but the impact resistance and transparency are poor. The wear resistance of PC material is poor, but the impact resistance and transparency are strong. Therefore, the flexibility of the pull rod box of PC material will be better than that of PP material. When impacted, PC material may have a slight depression, but PP material may crack. The pull rod box made of PP is heavier and cost-effective. The pull rod box made of PC is in line with the current trend and cost-effective.
