The adverse effects of styrene, what are the dangers of styrene to the body

The ** of expandable polystyrene is about dozens of yuan per cubic meter, and the cheap one is more than ten or twenty yuan. The ** of expandable polystyrene is affected by many aspects, such as brand, category, specification, market, etc. Before choosing to buy, it is necessary to understand and compare in many aspects.

Expandable polystyrene is a kind of polystyrene product with foaming agent. Abbreviated as "EPS". The appearance is colorless and transparent bead-like particles.

The commonly used foaming agent is low boiling hydrocarbons (such as petroleum ether, butane, pentane, etc.), which is prepared by styrene monomer in an autoclave to complete a reaction, called one-step method; It can also be polymerized and foaming agent is added to gradually penetrate into the polymer body, which is called the two-step method. After foaming, the foaming pores of one-step products are uniform and fine, and the elasticity of the product is good, but the molecular weight of the polymer is low and the quality is poor. II....

Long-term exposure can cause sore eyes, sore throat. What's more terrible is that styrene is chronic toxicity, and the harm to human blood and internal organs is chronic, affecting the male reproductive system, and the most serious consequences will lead to leukemia and cancer. Therefore, it is necessary to pay attention to protection.

Glad to answer useful questions for you.

1.As a monomer of synthetic rubber and plastics, it is used in the production of styrene-butadiene rubber, polystyrene and expanded polystyrene.

2.Copolymerization with other monomers to make a variety of engineering plastics for different purposes.

3.It is mainly used in the manufacture of audio and video products, disc boxes, lamps, interior decoration parts, and high-frequency electrical insulation parts;

4.train and vehicle parts, automotive parts, marine plastic parts, telecommunications and electrical parts, and building materials;

5.It can be processed into films, wire and cable sheaths, pipes, various hollow products, injection molded products, fibers, etc. It is widely used in agriculture, packaging, automotive and other industries.

Styrene is an organic compound formed by replacing hydrogen atoms in ethylene with benzene. Its molecular formula is C8H8. The electrons of vinyl are conjugated with benzene ring, insoluble in water, soluble in ethanol and ether, and gradually polymerized and oxidized in air.

Industrially, it is an important monomer of synthetic resins, ion exchange resins and synthetic rubber.

Translations of words in English, styrene, German, styrol, styren, vinylbenzol, phenylethylen (eig, chem), French, styrène

2. Network Explanation.

Styrene styrene (C8H8) is an organic compound formed by replacing a hydrogen atom of ethylene with benzene, the electrons of vinyl are conjugated with benzene ring, insoluble in water, soluble in ethanol and ether, and gradually polymerized and oxidized when exposed to air. Industrially, it is an important monomer of synthetic resins, ion exchange resins and synthetic rubber. On October 27, 2017, the World Health Organization's International Agency for Research on Cancer (IARC) released a preliminary list of carcinogens, and styrene was included in the list of class 2b carcinogens.
