plants turn to produce from solid re-PSF to HC re-PSF

HC re-PSF profits could reach 1,000yuan/mt at its best, while solid re-PSF profits were around the cost line. In 2020, HC re-PSF profits once reduced to below 500yuan/mt, but solid re-PSF was worse, and quality HTLS close virgin PSF was replaced by virgin PSF. Some plants in Hebei and Jiangsu changed the flexible production line to produce from solid re-PSF to HC re-PSF, or some plants chose to invest new HC re-PSF production lines.
