Polyisobutylene，PIB

Most polymer production processes, such as solution polymerization, bulk polymerization, emulsion polymerization, etc., have strict residue standards for volatile components, monomers, organic solvents, etc., resulting in a variety of Volatile component removal process.

Among them, vacuum screw extrusion technology, vacuum film scraping technology, flash evaporation technology, etc. are used by the majority of polymer companies.

However, the disadvantages of the first two, such as high energy consumption, high investment, high maintenance, and high operating costs, have not been solved. Ruihao Chemical adopts unique vacuum technology and special design to reduce operation and maintenance costs, reduce investment costs, and improve the removal efficiency of volatile components, thereby producing higher quality and more competitive polymer products. The process operation unit uses a static mixing heat exchanger as a preheating device, and is equipped with a high-efficiency static mixer to fill the eluent and enter the devolatilizer to achieve full removal of volatile components. According to the difference in product feed concentration, the unit can be designed as a continuous devolatilization process unit from one-stage pre-concentration to multi-stage complete devolatilization. Depending on the polymer system, the removal of volatile components can vary from 0.5% to 20 ppm (depending on the actual polymerization system).

For PIB, customers produce low molecular weight, medium molecular weight and high molecular weight polyisobutylene products according to different production requirements and product characteristics, which are applied to different occasions.

Shanghai Ruihao cooperates with European and American engineering consulting companies and Northwest University, a well-known domestic school, to jointly develop and research polymer polymer production. From the polymerization, devolatilization and finishing of isobutylene, Shanghai Ruihao can provide different processes and key equipment in each section.
