Information

Solvent polymerization
Solvent method (also known as slurry method or slurry method, slurry method) is the earliest polypropylene production process. However, due to the deashing and solvent recovery processes, the process is long and complicated. Since the 1980s, the solvent method has become stagnant and gradually replaced by the liquid bulk method.

Polypropylene Homopolymer prices

Process characteristics: (1) Propylene monomer is dissolved in an inert liquid-phase solvent (such as hexane), and the solvent is polymerized under the action of a catalyst, and the polymer is suspended in the solvent in the state of solid pellets, and a tank-type stirring reactor is used; (2) There are deashing and solvent recovery processes, the process is long and complicated, the equipment investment is large, and the energy consumption is high. However, the production is easy to control and the product quality is good; (3) The polypropylene particles are separated by centrifugal filtration and then boiled, dried and extruded to granulate.
solution polymerization
Process characteristics: (1) Using high-boiling straight-chain hydrocarbons as solvent, operating at a temperature higher than the melting point of polypropylene, all the obtained polymers are dissolved in the solvent and are homogeneously distributed; (2) The high-temperature stripping method evaporates and removes the solvent Obtain molten polypropylene, and then extrude and granulate to obtain pellet products.
