PVC is polyvinyl chloride (Polyvinyl chloride Abbreviation for polymer), corrosion resistance.PC is the abbreviation of Polycarbonate, which has impact resistance, thermal distortion resistance, good weather resistance and high hardness.ABS is an engineering plastic, the full name is “acrylonitrile-butadiene-styrene copolymer”, the English is Acrylonitrilebutadiene Styrene copolymers. It has high strength, good toughness and easy processing. The three components and materials are different. The three are the polymerization of small molecular organic materials into macromolecular materials, and the composition before polymerization is different, resulting in differences in composition, mechanical strength, heat resistance, etc. after polymerization.
The following are the advantages and disadvantages of several trolley cases:
ABS trolley case is a relatively new material, and it is also a relatively popular fashion material recently. The main feature is that it is lighter than other materials, the surface is more flexible and rigid, and the impact resistance is better to protect the items inside. It doesn’t feel strong when it is soft, but it is actually very flexible. The average adult has no problem standing on it. It is more convenient to clean. The disadvantage is that it is prone to scratches.
Oxford cloth This is a kind of nylon. The advantage is that it is wear-resistant and practical. The disadvantage is that it is the same. It is difficult to distinguish luggage at the airport, and it is relatively heavy, but there is no need to worry about the damage to the box. In the same way, with the increase of abs over time, the wear of the surface may appear for a long time after a few uses.
The pu boarding trolley case is made of artificial leather pu material. The advantage of this kind of case is that it is very similar to cowhide, it looks high-end, and it is not afraid of water like a leather case. The disadvantage is that it is not wear-resistant and not very strong, but the price is low. .
canvas Boxes of this kind of fabric are not very common, but for canvas, the biggest advantage is that it is wear-resistant like Oxford cloth, while the disadvantage is that the impact resistance is not as good as that of Oxford cloth. The color of the canvas material is very uniform, and some surfaces may be brighter. Looking good. Over time, there is an old and unique sense of vicissitudes.
The pvc trolley case is also known as the hard case. It looks like a tough guy. It is anti-drop, waterproof, impact-resistant, wear-resistant and fashionable. It can be said that it is much stronger than abs. Will worry about scratches due to rough handling. Because it won’t be obvious. The biggest disadvantage is that it is heavy, which is about 20 kilograms at every turn. You must know that many airlines limit it to 20 kilograms, which means that the weight of the box accounts for half.
cowhide
Generally speaking, cowhide is the most expensive. It is more expensive in terms of price/performance ratio. It is afraid of water, abrasion, pressure, and scratching. However, as long as it is properly kept, the box is very valuable. It is not environmentally friendly to use leather. Remember that there is no harm if there is no sale.
