Compared with materials such as wood, metal, cement, glass, etc., plastic has the following advantages and disadvantages.
Advantages: (1) Easy to form, high design freedom; (2) Easy to color; (3) Greater strength than metal; (4) Light specific gravity; (5) Easy to modify and obtain the desired performance; (6) Good electrical insulation; (7) Good water resistance and no rusting; (8) Good chemical resistance; (9) The energy consumed in production is less than that of metals; (10) As long as plastic waste is treated properly, it causes less damage and pollution to the environment than other materials.
Disadvantages: (1) Poor weather resistance, especially poor UV resistance, prone to aging under UV light; (2) Easy to generate static electricity; (3) High coefficient of thermal expansion and poor dimensional stability; (4) Low surface hardness, prone to scratches; (5) Poor durability and poor resistance to environmental stress cracking.

However, with the continuous development and progress of blending technology, as well as the achievements of high-performance general polymers, some of its shortcomings have gradually been improved, expanding the application fields of general plastics and making plastics increasingly important in the national economy.
