From daily life, we can see that PS plastics have played an important role in various industries. Our tableware, furniture, toys and so on, there will be PS plastic figure. Different from plastic bags, plastic bottles, different from PVC,PET and other common plastics, PS plastic is a kind of polystyrene plastic, the most widely used model is PS (polystyrene). The manufacturing process of

PS plastic is relatively simple. In the production process, the polymerization reaction can be carried out in two ways, one of which is to react into a polymer through two monomers when encountering linear olefins; and the other is Free radical polymerization when exposed to hydrogen peroxide. The advantages of this manufacturing process are simplicity, low cost and high manufacturing efficiency.

What are the characteristics of PS plastic? PS plastic hard, high transparency, high sunlight stability and durability. PS plastics also have good physical properties, such as tensile strength and cutting strength. PS plastic is not easy to deform, heat, stability is also very strong. At the same time, PS plastic has low density, light weight, good portability, easy processing into various shapes, very plastic.

about the application field of PS plastic, it can be widely applied to all aspects. In plane printing, for example, PS plastic is a very suitable material because it has a flat surface, high transparency, and can be processed into various shapes. The weather resistance of PS plastic is also very good and can be used indoors and outdoors for a long time. In food packaging, PS plastic can be made into a transparent and flat box, transparency makes food packaging more beautiful and easy to express and management. In industrial fields such as cabinets, tables and chairs, PS plastic is a low-cost, easy-to-process material, which is widely used in the manufacture of furniture, toys, and other household goods.

At the same time, we also need to mention the environmental protection of PS plastics. In industrial production, there will be some waste PS plastic fragments, if these waste plastics are not properly treated, it will become a threat to environmental pollution. However, the waste of household PS plastic tableware after washing and processing, and the fresh PS plastic fruit and vegetable bags produced by the vegetable market, after recycling and garbage sorting, its impact on the environment will be greatly reduced.

PS plastic plays an indispensable role in our daily life. Whether it is its characteristics or its application, we can't help but wonder about it. I believe this article can give you a deeper understanding of "PS" plastics.
