Description:
Information

Hiscien has started the engineering work on the PET continuous SSP process in the year 1999. Based on the experiences of many different projects years, Hiscien has developed its own advanced SSP technology featuring low production cost and wide capacity range that is applicable to the production of high viscosity chips for the spinning of different type of industrial yarn and the production of different type of bottle grade chips. 

·Main Process of SSP

The process can be one stage or two stages according to the capacity and the specification requirements.

➢One Stage Process
