Storage:
1. Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. The package should be sealed to avoid contact with air. It should be stored separately from oxidants and acids, and never mixed. It should not be stored in large quantities or for a long time. Use explosion-proof lighting and ventilation facilities. Mechanical equipment and tools that are prone to sparks should not be used. The storage area should be equipped with leakage emergency treatment equipment and appropriate containment materials.
2. Use galvanized iron barrels for packaging, add inhibitors during packaging, and store at low temperature (below 25℃) or in a refrigerated warehouse to prevent polymerization and deterioration. Keep away from fire sources and avoid direct sunlight. The storage period is one month. Store and transport as flammable and toxic items.
Safety protection: This product is toxic, less toxic than benzene, but it will irritate the skin and respiratory tract at high concentrations.
About Us: With over many years as a certified Styrene manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Styrol Applications
1. Used in organic synthesis and resin synthesis
2. Mainly used as raw materials for polystyrene, synthetic rubber, engineering plastics, ion exchange resins, etc.
3. Used to prepare copper plating brighteners for leveling and brightening
4. The most important use is as a monomer for synthetic rubber and plastics, used to produce styrene-butadiene rubber, polystyrene, and foamed polystyrene; it is also used for copolymerization with other monomers to manufacture engineering plastics for various purposes. For example, ABS resin is obtained by copolymerization with acrylonitrile and butadiene, which is widely used in various household appliances and industry; SAN obtained by copolymerization with acrylonitrile is an impact-resistant and bright resin; SBS obtained by copolymerization with butadiene is a thermoplastic rubber, which is widely used as a modifier for polyvinyl chloride and polypropylene.
5. In addition, a small amount of Styrol is also used as an intermediate for spices. Styrol is chloromethylated to obtain cinnamyl chloride, which is used as an intermediate for the non-narcotic analgesic qiangtongding. It is also used as the original drug for the cough and expectorant yi Kezin and the anticholinergic drug Weichangning.
6. Electron microscope analysis, organic synthesis.
7. Electron microscope analysis, organic synthesis. Used in ICP-AES, AAS, AFS, ICP-MS, ion chromatography, etc.
