Pbt polymerization
SpletSolid state polymerization technology now allows continuous polymerization, which replaces the older batch technology. This report updates two previous PEP reports on the technology and cost of producing PBT. The sizable growth in the market for PBT has increased demand for BDO. We examine five processes for producing BDO. SpletMore than 60 CP production lines have been contracted and built by OBHE, of which the process of 5 reactors, 4 reactors and 2 reactors are adopted, and in which the minimum and maximum capacity of single line can reach 30t/day and 1800t/day respectively. The technology of differential polyester has been applied in CP production by OBHE for the ...
