Among the host of new additives at K 2007 were a number of unusual entries: additives to add scratch resistance or reduce odor, leaps ahead in PP clarifying, specialized antioxidant protection for nanocomposites, a growth enhancer for greenhouse films, and a naturally free-flowing TiO2. In addition, “Green” was the theme of exhibits that highlighted “all-natural” additives for biopolymers, and colors to enliven recycled resins.
Lower cost, higher quality and productivity, and the potential for lightweighting beyond anything yet seen are benefits claimed for a new continuous compression molding process for making PET bottle preforms.
Four months ago, we reported on a new induction barrel-heating system that promises to save up to 70% in energy costs (see Learn More). Here’s an update on another novel barrel heating—and cooling—system that boasts similarly large savings and has been out in the field long enough to build a track record.
