What attracts some 75,000 engineers and their counterparts from 100 countries to Chicago's McCormick Place every three years? The National Plastics Exposition (NPE '97) sponsored by The Society of the Plastics Industry! With these impressive numbers as a setting, it's little wonder that some 1,700 exhibitors displayed an estimated 1,000 new plastics-related products and services. Here's a sampling of some material and molding unveilings. On the materials front, the merger, joint- or licensing-agreement, and buy-out mania continues. Moreover, some of the major resin producers are giving their more specialized in-house operations a freer rein to prove their worth in the marketplace. For example, Hoechst Technical Polymers announced the formation of the company as a separate legal entity to be called Ticona, while Clariant Masterbatches Div. will merge with the Hoechst Specialty Chemicals Group …In a like move, GE Plastics revealed that its film operations have become a separate profit and loss center …Union Carbide Corp. disclosed the sale of its recycling operations to Ecoplast Corp. )…Shakespeare Monofilament, a division of K2 Inc., divulged the purchase of the ResistatTM line of carbon black suffused nylon monofilament from BASF Corp. …AlliedSignal Plastics and Advanced Elastomer Systems (AES)unmasked a non-exclusive agreement to jointly develop applications for nylon-based "soft touch" products using new grades of AES Santoprene® that chemically bond to Allied Signal's Capron® and Nyprel® resins. And two leading players in the polycarbonate resins market, Bayer AG and GE Plastics, reported they will jointly develop abrasion-resistant auto glazing.
