The advantages and disadvantages of different materials

When people choose to travel, the must-have is the suitcase. When buying suitcases, there are many factors to consider, such as the material of the suitcase, the quality of the suitcase, etc. There are many kinds of materials for the suitcase, and suitcases are divided into hard cases and soft cases. , Are made of different materials, so what material is good for the trolley case, and which material is durable? What are the advantages and disadvantages of these different materials, let me understand together.

1. Oxford cloth

The name of Oxford cloth comes from Oxford University. It is a combed cotton fabric named by the University of Oxford. Oxford cloth is divided into five kinds of material fabrics, checkered Oxford cloth, cotton Oxford cloth, full stretch Oxford cloth, Tige Oxford cloth, weft A strip of Oxford cloth. Our common oxford brazil rod box is generally used tig Oxford cloth.

Advantages: The fabric of Oxford cloth is novel in design, has unique craftsmanship, and has a very strong three-dimensional effect. When Oxford cloth is added with PU material, it can make it more waterproof and very wear-resistant.

Disadvantages: Because the fabric is very soft, when taking transportation, such as airplanes, luggage will be checked. Violent checking can easily damage the fragile things in the box.

2. PU

The trolley case made of PU material is generally made of polyurethane fiber, which is an organic polymer material and the fifth largest plastic. PU is resistant to ultraviolet rays, high temperature and washing.

Advantages: PU material has high resilience, light and soft texture, long life, strong wear resistance, excellent shock absorption and anti-skid performance.

Disadvantages: PU material is easy to damage when facing sharper objects, because the soft box will easily break the fragile items in the box.

3. Canvas

Canvas is made of a hemp fabric or thick cotton fabric. At first, some sails used this cloth to make sails, so this kind of coarse cloth is called canvas. Canvas can be used to temporarily build warehouses or tents. Canvas is a kind of environmentally friendly fabric, low-key and ostentatious, but canvas fabric suitcases are rare on the market.

Advantages: It has good waterproof and abrasion resistance.

Disadvantages: Not scratch-resistant, it is easy to scratch the box when encountering sharp objects, and it is not resistant to pressure or impact.

4. ABS

ABS material is composed of a terpolymer of three monomers, namely acrylonitrile, butadiene, and styrene. The content of the three monomers is changed to make various resins. Acrylonitrile has the effect of heat resistance and corrosion resistance, butadiene has high elasticity and flexibility, and styrene has good thermoplasticity.

Advantages: ABS suitcase has good high resilience, pressure and impact resistance, and will not deform in high temperature weather.

Disadvantages: The suitcase made of ABS material is very fragile. When it is subjected to different impacts, it is easy to damage the box body when bumped.

5. PC

PC material is a high molecular weight polymer containing polycarbonate base in the molecular chain. Polycarbonate has high toughness, is colorless, odorless, non-toxic, has good flame retardancy, wear resistance and oxidation resistance. The PC suitcase is very light, flexible, strong and durable. Coloring is not easy to fade, and PC suitcases are now widely used.

Advantages: non-toxic, colorless and tasteless, environmentally friendly. Has high toughness and resilience. Durable, bright and beautiful in color.

Disadvantages: PC cases are more expensive than ABS suitcases, and they are not wear-resistant and prone to scratches.

6. Aluminum Magnesium Alloy

The main components of aluminum-magnesium alloys are aluminum and magnesium, with more aluminum and a small amount of magnesium doped to enhance the hardness of the material. Aluminum-magnesium alloy has very good corrosion resistance and high strength. The density is small, the strength is high, it has a certain bearing capacity and is not easy to deform.

Advantages: The aluminum-magnesium alloy suitcase is very sturdy, not afraid of violent transportation at the airport. The shock resistance is very strong, the strength is very high, and it is more load-bearing than other suitcases. Many PC boxes add aluminum -magnesium alloy frames to strengthen the load-bearing capacity of the box.

Disadvantages: It is not easy to rebound and deform after being hit. It is expensive and will be more expensive than PC or suitcases of other materials.

7. PP

PP material is also known as polypropylene. This material is characterized by low density, non-toxic, colorless and tasteless, strong hardness and good heat resistance, so the trolley case made of pp material is not easy to crack, and it is waterproof, pressure and wear resistance, but The appearance is simple and common, and the cost performance is relatively low. There are many trolley cases made of pc or other materials on the market that are more durable and cost-effective than those made of pp.

Advantages:

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

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

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, and has a pure texture, making it safer to use.

Disadvantages:

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

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

3. The colorability is not good, and the color will fade easily after long-term use.

4. The flame retardancy is not good and easy to burn.

5. Trolley case made of pp material has poor toughness, high static electricity, and poor dyeability, printability and adhesion.
