Eastman CB12 PET (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Voridian CB12 polymer is a polyethylene terephthalate resin designed specifically for the carbonated soft drink (CSD) and other beverage markets. CB12 delivers fast, efficient processing and good overall bottle properties. This polymer is formulated to provide improved efficiencies in preform and bottle production while delivering a robust processing window. Bottles made with CB12 deliver improved barrier with continued excellent performance in creep and environmental stress-crack resistance. The pellets have a weight of 2.0g/100pellets Applications/Uses Bottles Carbonated soft drink containers Key Attributes Excellent performance in stress-crack resistance Fast, efficient processing Improved barrier Robust processing window
