Review NPE Review Even

Review NPE Review Even if NPE, ‘The International Plastics Showcase’ in Chicago from June 22 to 26, 2009 had a decrease in the number of visitors by 30%, a good portion of the approximately 44,000 visitors were very interested in bioplastics. At least this was our impression when we attended our booth in the West hall. After a comprehensive preview of this big plastics show in the last issue, we just add a few more small notes here. www.npe.org API S.p.A. from Mussolente, Italy presented APINAT biodegradable elastomers. Apinat is available in softer grades with 60-90 Shore A and in harder grades with 35-85 Shore A. The biodegradability meets EN 13432 and ASTM 6400 standards. Apinat can be processed using all methods for plastics, such as injection moulding. extrusion blow moulding, calendering and hard/soft over- or co-moulding onto most of the biodegradable plastics commercially available. www.apiplastic.com Polyvel, Hammonton, New Jersey, USA have developed in conjunction with NatureWorks a series of masterbatches based on Ingeo PLA designed for use in film, foam, injection moulding, blow moulding and sheet extrusion. Their clarifier S-1378 not only improves the clarity of PLA but it also raises the heat deflection temperature, as stated in Polyvel’s NPE brochure. Another clarifier for PLA (S-1417) can be used to reduce the cycle time. www.polyvel.com Jamplast, Ellisville, Missouri, is the largest distributor of biopolymers in North America. The family-owned company is a one-stop source for biopolymers, engineering polymers and commodity grade thermoplastics. Jamplast is currently an authorized distributor of NatureWorks biopolymers, Cereplast biopolymers, Merquinsa Pearlthane, PSM North America and others. At NPE Jamplast hosted a luncheon with presentations from Mark Verbruggen (NatureWorks), Frédéric Scheer (Cereplast) and Daniel Tein (PSM North America). www.jamplast.com PolyOne launched three new products at NPE: The Resound platform of biopolymer compounds is formulated with a 30% minimum bio-derived content and offers a substantial boost in performance for current and future bio-based materials. Key improvements include levels of heat tolerance and impact resistance unobtainable with neat bioplastics, as stated by PolyOne. Resound compounds combine compatible engineering thermoplastic resins with bio-based polymers such as PLA, PHB, PHBV, and biopolyesters. Future grades may take advantage of biopolymer resins currently in development but not yet commercially available. Initial Resound grades feature heat resistance (HDT) up to 120°C (248°F) and impact resistance up to 53 J/m (12 ft-lb/in). Versaflex BIO TPEs (Thermoplastic Elastomers) for injection molding are formulated with 63 to 70 % renewable resources, compared to typical compounds that use a maximum of 15 or 20 %. The Versaflex BIO family of TPEs compares favorably to typical styrenic-based TPEs The translucent grades are available in a range of 40 to 70 Shore A hardness. Merquinsa and PolyOne announced the world’s first halogenfree flame-retardant biobased thermoplastic polyurethane jointly developed by the two companies. Merquinsa’s Pearlthane ® ECO technology, a polyether polyurethane based on natural renewable sources will be marketed globally by PolyOne as part of the OnFlex TM family of thermoplastic elastomers. The minimum amount of natural renewable sources in the polyurethane resin 50% (as certified by ASTM D 6866). www.polyone.com OnFlex for wire and cable applications 12 bioplastics MAGAZINE [04/09] Vol. 4

Bioplastics hot topic at SPE‘s ANTEC 2009 Review The Bioplastics Special Interest Group (SIG) at the Society of Plastic Engineers (SPE) was created in September 2008 for the purpose of providing a unified forum for promoting open exchange of scientific and engineering knowledge related to polymeric materials that are fully or partially biobased with the ‘Cradle-to-Cradle’ emphases. The areas of interest include synthesis, characterization, processing, structure-property relationships, degradation, product design and development, application, modeling, regulations and compliance and life-cycle analyses. To achieve these objectives, the Bioplastics SIG collaborates closely with other interested technical divisions of SPE, national and international organizations, associations, and institutions to coordinate dissemination of the accumulated knowledge and understanding through appropriate channels. ANTEC 2009 on June 22 in Chicago was the first opportunity to support the above mentioned mission of the Bioplastics SIG. The two day session provided a great forum to bring the exports together, discuss new results of research and practical aspects of this field. The Monday morning session, which covered papers about the properties of PLA, PLA foams and PLA composite materials, was opened by a keynote lecture given by Mr. Richard Bopp from NatureWorks, titled ‘Advances in Ingeo Biopolymer Technology for Durable Applications’. The afternoon session was dedicated to synthesis of and properties of thermoplastic starch and other bioplastics. This session was opened by an overview of renewable fillers for thermoplastics - challenges and opportunities, a keynote lecture, given by Prof. Leonardo Simon from University of Waterloo, Canada. The Tuesday sessions were organized jointly with the Flexible Packaging division, focusing on sustainability. The morning session dealt with processing costs, environmental impact, life cycle estimation and screw design considerations. Mr. James Huang as a keynote speaker from Bemis Company, Inc. gave a presentation about the design considerations for food packaging using bioplastic materials, while Mr. Eric Greenberg from Eric F. Greenberg, P. C. also as a keynote speaker, gave an overview about the laws associated sustainability. The afternoon session started with another keynote talk, given by Prof. Rafael Auras from Michigan State University, covering the assessment of sustainable packaging systems. The rest of the presentations dealt with property improvements (impact, rheological, thermal) of bioplastic polymers for packaging applications. www.4spe.org Environmental Protection – Easily Retrofitted Production of 6-layer-fuel-jerry cans with barrier properties meeting the strict emission regulations cost effectively retrofitted onto your existing blow molding machine.
