Polystyrene (Polystyrene) referred to as PS, is a colorless transparent or white translucent rigid plastic. It is polymerized from styrene monomer and has certain hardness, toughness and heat resistance. Among plastics, polystyrene is one of the earliest widely used types. Because of its good physical properties and molding ability, it is widely used in the production of various plastic products, such as cups, fresh-keeping boxes, toys, electrical housings, etc.

the characteristics of polystyrene:

1. Lightweight and hard: Polystyrene thermoplastic is a relatively light plastic material, known for its hardness and rigidity.

2. Good formability: Polystyrene can be molded and compounded after heating, which is one of the reasons for its wide application.

3. Good transparency: Polystyrene hard plastic transparency is better, can be dyed in the production of products as needed, can also be added to other ingredients to improve its transparency and toughness.

4. Corrosion resistance: Polystyrene thermoplastics are acid and alkali resistant and will not be corroded by solvents such as food grease and alcohol.
The use of
polystyrene:

1. Food packaging: Because polystyrene has high safety, is not easy to deform, and has good heat sealing properties, polystyrene plastic is often used in the production of various food packaging.

2. Furniture decoration: Polystyrene plastic has good transparency, easy processing, corrosion resistance, and a certain degree of rigidity. These functions make it widely used in furniture decoration and interior decoration.

3. household goods: due to the good formability of polystyrene, pigments of various colors can be added, and it is easy to produce household goods such as cups, plates and bowls of various colors, which are deeply loved by consumers.

4. Underground pipeline: Because polystyrene has good water resistance and chemical resistance, it is used as underground pipeline to prevent leakage.

the environmental protection problem of polystyrene:

Although polystyrene plastic has good physical properties and molding ability, it is not easy to degrade and easy to accumulate in nature, which leads to environmental pollution and health problems. However, many companies and institutions are looking for solutions. For example, the promotion of polystyrene recycling, the development of biodegradable polystyrene, the use of recyclable or reusable polystyrene products.

polystyrene is a commonly used plastic with many advantages, it also has environmental problems. We should actively look for solutions to raise people's awareness of environmental protection and protect our environment together.
