Brief illustration over polymerization rate
 CCFGroup polymerization rate is a comprehensive rate calculated on O/R change of China polyester plants, calculating formula is as below: 

Polymerization rate= daily China polyester output*365/annual polyester capacity 
Polyester products include direct-spun PFY, PSF, PET fiber chip, PET bottle chip and PET film. Polyester annual capacity refers to design capacity. Polymerization rate is correlated with direct-spun PFY, PSF, PET fiber chip, PET bottle chip O/R, but detailed calculation involves more complex factors, please see insight in below link.
