The advantages of PP material trolley case

1. The density is relatively small, only 0.89-0.91, which is one of the lightest materials in plastics, so the PP material trolley case is lighter in weight.

2. It has good mechanical properties, so the pp trolley case is more pressure-resistant and impact-resistant.

3. It has high heat resistance and is not afraid of high temperature.

4. The pp trolley case is corrosion-resistant, has good chemical properties, is not easy to absorb water, and does not react with most chemicals.

5. The pp trolley case is non-toxic, tasteless, pure in texture, and safe to use.

Disadvantages of Pp material trolley case

1. The cold resistance of pp material is poor, so it is not resistant to impact at low temperature and is not suitable for winter use.

2. The pp trolley case is easy to age under the action of light, heat and oxygen.

3. The coloring is not good, and it is easy to fade after long-term use.

4, the flame retardancy is not good, easy to burn.

5. The trolley case made of pp material has poor toughness, high static electricity, and poor dyeing, printing and adhesion.
