Polypropylene suitcase (pp) and polycarbonate suitcase (pc).
luggage has been widely used in long-distance and short-distance travel. Currently, the luggage styles on the market are different, the materials are different, and even the subdivision of the use, commercial use, travel use, and moving use; from the material, there are nylon materials. , aluminum alloy material, ABS material, pp material and PC material, this article mainly introduces the difference between polypropylene (pp) suitcase and polycarbonate suitcase (pc).
First understand what Polypropylene and Polycarbonate are.
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat resistant. It is a white, mechanically rugged material and has a high chemical resistance. Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling. In 2013, the global market for polypropylene was about 55 million tonnes.
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as “Other”, 7 on the RIC list.
Look at the suitcase of PP material and PC material
- Polypropylene suitcase (PP)
The main material of this suit is polypropylene, equipped with standard TSA anti-theft lock lock, 4 mute casters, aluminum telescopic rods. The outstanding feature is that it is equipped with a mobile power slot, which allows you to charge your phone. Easy to use mobile phone. polypropylene suitcase is the lightest available on the market. Although relatively resilient, polypropylene is not as flexible or damage resistant as polycarbonate.
- Polycarbonate suitcase (PC)
One of the most popular materials used in the construction of hardsided luggage, polycarbonate, is extremely durable and offers some flexibility and give. This makes it resistant to rough handling. It is also available in many colors and patterns.
This table briefly explains the difference
| Polycarbonate Suitcase | Polypropylene Suitcase | |
| Why should I buy it? | Strongest of all three materials. | Great versatility, durable and lightweight. |
| Advantages | Very strong, can withstand absuse. | Most versatility, a combo of light weight and durability. |
| Disadvantages | Heavier than others due to heavier duty plastic. | Not as durable as polycarbonate. |
| Durability | Most durable. | Medium durability. |
| Weight | Heaviest of all three. | Lightest on the market. |
| Price | Most expensive, depending on brand. | Moderately priced, depending on brand, (close to the same price as polycarbonate) |
| Brands | Most major brands offer polycarbonate. | Typically, most major brands offer polypropylene. |
