Description
Styrene
Styrene, molecular formula C8H8, is an organic compound formed by replacing one 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 after exposure to air. . Industrially, it is an important monomer such as synthetic resin, ion exchange resin, and synthetic rubber.

Use Of Gibberellic acid:
- The most important use is as a monomer for synthetic rubber and plastics, used to produce styrene butadiene rubber, polystyrene, styrofoam; also used in copolymerization with other monomers to produce a variety of engineering plastics for different purposes. For example, ABS resin is obtained by copolymerization with acrylonitrile and butadiene, and is widely used in various household appliances and industries; SAN prepared by copolymerization with acrylonitrile is an impact-resistant, bright-colored resin; and copolymerized with butadiene. SBS is a thermoplastic rubber widely used as a modifier for polyvinyl chloride and polypropylene.
- Styrene is mainly used in the production of styrene series resin and styrene-butadiene rubber. It is also one of the raw materials for the production of ion exchange resins and pharmaceuticals. In addition, styrene can also be used in pharmaceutical, dye, pesticide and mineral processing industries.
Package Of Gibberellic acid:
180kg/drum
Storage:
Usually the product is added with a polymerization inhibitor. Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. The package is sealed and must not be in contact with air. It should be stored separately from oxidants and acids, and should not be mixed. Not suitable for large storage or long-term storage. Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
