[Chemical Knowledge]：Styrene: deciphering the true face of this chemical

Read： 382 Time：18months ago Source：Transform the World with Simplicity

Styrene is a colorless liquid with a pleasant aromatic odor at room temperature and pressure, with a chemical formula of C8H8 and a molecular weight of 104.15. Its CAS number is 100-42-5, and it was once called a "key product" because styrene is widely used in the global chemical industry to make plastics, fibers, cosmetics and other products.

In the manufacture of plastics, styrene can be used to produce polystyrene (PS), acrylonitrile-styrene-acrylate copolymer (ABS), styrene-butadiene-styrene copolymer (SBS) and other plastic products. These plastics have the characteristics of high strength, high toughness and low specific gravity, and are widely used in electrical appliances, automobiles, building materials and other fields.

In addition to plastics, styrene can also be used to produce fiber, rubber, ceramics, pesticides and other products. At the same time, styrene is also one of the main ingredients in cosmetics and perfumes, which can give the product a charming fragrance.

However, styrene is also highly toxic and hazardous. Its inhalation, intake, contact with the skin and other ways will have a negative impact on human health. Long-term exposure to styrene may cause cancer, affect the function of the nervous and reproductive systems, and cause skin allergies. Therefore, the production, use and handling of styrene need to be strictly controlled to avoid harm to the human body.

In terms of sustainability, the production of styrene requires a large amount of non-renewable resources such as oil, and also produces a large amount of environmental pollutants such as carbon dioxide. Therefore, how to find alternative production methods and reduce the environmental burden has become an urgent problem for the chemical industry.

In general, styrene, as an important organic compound, has a wide range of applications in industry and consumption. But at the same time, we also need to pay attention to its harmfulness and sustainability, so as to find more safe and environmentally friendly production and use methods to protect human health and sustainable development.
