The first bottle-grade PET resins produced with a titanium catalyst reportedly enable higher filling temperatures, lower acetaldehyde 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. Titanium-based, antimony-free PET resins are made at Wellman's plants in Florence, S.C., and Pearl River, Miss. Among them is new ThermaClearTi 842 for hot-filled juices and sports drinks. This heat-setting resin is said to withstand 5 ° to 10 ° F hotter filling than previous grades. Also new is PermaClearTi 818 for carbonated softdrink and water bottles. It reportedly allows molding preforms at 20 ° 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
