Dow LIGHTER™ C98 Polyethylene Terephthalate (PET) Resin (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET)
Material Notes:	LIGHTER™ resins are polyethylene terephthalate produced from PTA and MEG. These polymers are specifically designed for the production of beverage, food and other liquid containers and for thermoforming. LIGHTER™ C98 is preferred for bottles containing highly carbonated soft drinks, which require high mechanical properties and low gas permeability. It is recommended also for the production of extruded thermo formable sheets. Information provided by Dow
