Material Notes:

STYRON® 666D general purpose polystyrene resin is used in injection molding applications, particularly for medical, pharmaceutical and food uses. It offers excellent clarity, intermediate flow characteristics, fast cycles, and good heat resistance. When used unmodified for the manufacture of food contact articles STYRON 666D complies with the US Food, Drug and Cosmetic Act and Food Additive Regulations 21 CFR 177.1640. The regulations should be consulted for complete details.Data provided by Dow Chemical.Americas Styrenics was formed in 2008 as a joint venture between Dow Chemical and Chevron Phillips Chemical Company. Styron was a Dow trade name before the JV formation.
