Product introduction and features
Styrene, is an organic compound, chemical formula is C8H8, the electron of vinyl and benzene ring conjugate, insoluble in water, soluble in ethanol, ether and other organic solvents, is an important monomer of synthetic resin, ion exchange resin and synthetic rubber.
use
The most important use is as a synthetic rubber and plastic monomer, used to produce styrene butadiene rubber, polystyrene, polystyrene foam; It is also used to copolymerize with other monomers to make engineering plastics of different uses. Such as with acrylonitrile, butadiene copolymer ABS resin, widely used in a variety of household appliances and industry; SAN copolymerized with acrylonitrile is a resin with impact resistance and bright color. SBS copolymerized with butadiene is a kind of thermoplastic rubber, widely used as polyvinyl chloride, polypropylene modifier.
Styrene is mainly used in the production of styrene series resin and styrene BUTADIene rubber, is also one of the raw materials for the production of ion exchange resin and medicine, in addition, styrene can also be used in pharmaceutical, dye, pesticide and mineral processing and other industries. 3. Usage:
For best performance, it is recommended to add after dilution. The amount of water used depends largely on the application system. The user should determine the best amount by experiment before use.s.
