Luggage has become a necessity in life. It is indispensable for business trip, school and travel. In addition to paying attention to the style and price, the material is also very important, which directly determines how long it can be used.
Now the common materials on the market are pc, abs pc, pu and aluminum magnesium alloy. What kind of trolley case is better?
Trolley case is mainly made of five materials:
Pc is a tough thermoplastic resin, which is characterized by light weight, strong flexibility, high elasticity, heat resistance and transparency. Trolley box of the same size, PC is much lighter than ABS, etc; It is resistant to falling, abrasion and compression. There is no problem for adults to stand on it. It is the strongest trolley case. It can withstand the temperature of - 40 ° to 130 ° C, with transparency up to 90%, and can be dyed at will, which is fashionable and beautiful. The disadvantage is that the cost is very high.
Abs is a popular material recently. Its main characteristics are light weight, flexibility and strong crack resistance. This material looks fragile, but its actual flexibility and hardness are beyond your imagination, but slightly worse than that of the PC. Therefore, the trolley case made of this material is usually thicker than the PC. The disadvantage is that it is easy to scratch, so use it carefully.
Pu is a kind of artificial leather. its main advantages are long service life, good oil resistance and good water resistance. This kind of material looks like cowhide. It looks very high-end, easy to take care of, and the price is relatively low. The disadvantages are non abrasion resistance and insufficient strength.
Canvas is a thick cotton linen fabric. The main advantages are firm and durable, good waterproof performance and firm hand feel. The fabric is stronger, harder to wear, thicker to touch, and waterproof. The disadvantage is that it is airtight, and it will feel old after being used for a long time.
Magnesium aluminum alloy is a kind of metal material, which has the advantages of moistureproof, shockproof, fireproof, sealing, oxidation resistance, firmness, etc. This metal material is a high-grade trolley case. Although it is metal, it is light and impact resistant. It can protect valuables, such as laptops, from deformation due to extrusion, and has good load-bearing capacity. The disadvantage is that it will deform under large impact and is not easy to repair.
You can choose the most appropriate trolley case according to your own situation.
