Plastic products are widely used in various fields due to their unique material properties, but they also have significant limitations. Their advantages and disadvantages are as follows:
Core Advantages
Lightweight and Portable: Plastic has a density only about 1/6 that of metal, making it much lighter than traditional metals and glass, significantly reducing the burden of transportation, handling, and use.
Strong Corrosion Resistance: Excellent chemical stability; it does not easily react with acids or alkalis and will not rust like metal, making it suitable for humid and corrosive environments.
High Processing Flexibility: It can be quickly molded into any complex shape through injection molding, extrusion, and other processes, resulting in high production efficiency and meeting the customized needs of different products.
Low Cost: Raw materials are readily available, and processing energy consumption is far lower than that of metals, making large-scale mass production a significant economic advantage.
Excellent Insulation Properties: It is a good electrical insulator, effectively preventing short circuits and electric shock risks, and is widely used in the casings of electronic appliances and cable protection.
Durable and Waterproof: Most plastic products are waterproof, impact-resistant, and not easily broken, exhibiting excellent durability for everyday use.
