Titanium-based PET raises the bar.The first bottle-grade PET resins produced with a titanium titanium (tītā`nēəm, tĭ–) [from Titan], metallic chemical element; symbol Ti; at. no. 22; at. wt. 47.88; m.p. 1,675°C;; b.p. 3,260°C;; sp. gr. 4.54 at 20°C;; valence +2, +3, or +4. catalyst reportedly enable higher filling temperatures, lower acetaldehyde acetaldehyde (ăs'ĭtăl`dəhīd) or ethanal (ĕth`ənăl'), CH3CHO, colorless liquid aldehyde, sometimes simply called aldehyde. It melts at −123°C;, boils at 20. levels for improved taste/odor, faster molding, and lightweighting opportunities. R&D director Jim Bruening at Wellman, Inc., Shrewsbury, N.J., believes that titanium could become the catalyst of choice industrywide in·dus·try·wide adv. & adj. Throughout an entire industry: sales that have decreased industrywide; industrywide cooperation. . Titanium-based, antimony-free PET resins are made at Wellman's plants in Florence, S.C., and Pearl River Pearl River, uninc. village (1990 pop. 15,314), Rockland co., SE N.Y., near the N.J. line. It is a residential suburb of New York City, and a computer and telecommunications research and development center. Pearl River River, central Mississippi, U. , Miss. Among them is new ThermaClearTi 842 for hot-filled juices and sports drinks sports drink Performance drink Sports medicine A thirst-quenching beverage used in sports-related activities, which may boost energy and/or help build muscle mass; water, sugar, salt, potassium are common to all SDs. See Hydrotherapy, Water. . This heat-setting resin is said to withstand 5[degrees] to 10[degrees] F hotter filling than previous grades. Also new is PermaClearTi 818 for carbonated soft drink and water bottles. It reportedly allows molding preforms at 20[degrees] F lower melt temperature and 5% to 10% faster. This is said to save energy and achieve 1 to 2 ppm lower acetaldehyde levels, particularly desirable for water bottles. Tel: (732) 212-3300 * www.wellmaninc.com [ILLUSTRATION OMITTED] |
