Yaxing adopts CPE production technology of HCl-phase suspension, which was solely owned by Hoechst, Germany. This technology is leading the CPE industry and is characterized with flexible operation and best adaptability for serial products with respectively distinct features, thus different applications of different customers can be reached. Reacting with the presence of high density HCl as the medium, the CPE produced is uniformly chlorinated and has better flexibility, higher whiteness and is most suitable for high-end applications in plastics and rubbers. The HCl as the byproduct is fully recovered, which ensures environmentally friendliness and cleanness.
