Eastman 9921W PET Injection Molded (discontinued **)
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Voridian PET 9921W is a copolymer PET. Typical applications include containers for automotive parts, household products, and pharmaceutical and food packaging. Voridian PET thermoplastic polyesters are condensation polymers produced by a continuous melt-phase polymerization process followed by a solid-state polymerization process. It is a copolymer PET that has been crystallized. Color concentrates, additives, and denest versions of 9921 are available on request. Applications/Uses APET sheet Automotive parts containers Food packaging Household products containers Pharmaceutical containers Wine and liquor containers Water bottles Carbonated soft drink bottles
