German-headquartered Kautex Maschinenbau GmbH, a manufacturer of extrusion blow-molding systems, has demonstrated processing of BASF's Styrolux® 3G 46 (styrene-butadiene copolymer) by extrusion blow-molding for the first time in Europe. Kautex Maschinenbau has recently produced intricately shaped bottles using this styrene-butadiene copolymer (SBC) on a high-performance extrusion blow-molding machine. BASF launched this plastic as a blow-molding brand onto the market in early 2008.
Apart from transparency and high stiffness, producing bottles with an integrated handle using this material makes it easy to form the weld line. The company claims the SBC (styrene-butadiene block copolymers) polymer also allows lower processing temperatures and shorter cycle times than with comparable packaging materials, and besides, this plastic weighs much less than PET or PVC. This makes Styrolux a cost-effective material for manufacturing products that are made by extrusion blow-molding.
