Material news New

Material news New amorphous PHA grades as performance additives for PVC and PLA Metabolix (Cambridge, Massachusetts, USA) is launching its new line of amorphous polyhydroxyalkanoate (PHA) grades to be used as performance additives for PVC and PLA. Production of the new materials is underway at a U.S. pilot plant and will ramp up to 270 tonnes (600,000 pounds) annual nameplate capacity during 2016. “The commercial launch of these new grades of amorphous PHA represents an important development for Metabolix as we advance our business strategy focused on specialty biopolymers,” said Johan van Walsem, Metabolix’s chief operating officer. “This expanded pilot capacity is strategic for us to support existing customers and opens new market development opportunities in our target application spaces.” Amorphous PHA (a-PHA) is a softer and more rubbery (low glass transition temperature or T g) version of PHA that offers a fundamentally different performance profile from crystalline forms of PHA. Metabolix’s a-PHA is produced by fermentation and extracted using a patented solvent recovery process. The production process has been reviewed by EPA and recently cleared the Premanufacture Notice (PMN) requirement for new materials placed into commerce. Several certifications are pending on a-PHA as a biobased material and for the full range of biodegradation scenarios enabled when a-PHA is used alone or with other complementary materials. Metabolix plans to seek FDA clearance for a-PHA in food contact applications, which would further expand the range of PHA compositions available for use in food contact materials. Metabolix previously received FDA clearance for use of its semi-crystalline PHA grades in food contact applications. At low loading levels, a-PHA can serve as a process aid and performance modifier for PVC. It increases productivity during processing and enhances mechanical performance, with the potential to also deliver cost savings in PVC material systems. In highly filled composite systems, the use of a-PHA enables increased use of wood pulp, mineral fillers and PVC recyclate to replace virgin PVC and achieve improved mechanical properties. Metabolix is working closely with customers on a wide range of applications utilizing a-PHA as a modifier for PVC. These applications include a floor backing material that utilizes PVC recyclate, a highly-filled vinyl flooring system, wire and cable insulation, roofing membranes, PVC/wood polymer composites and other construction and building materials (see p. 23). Amorphous PHA also complements the bio-content and compostability profile of the biopolymer PLA while delivering significant improvements in mechanical properties such as increased toughness, strength and ductility. Based on these product advantages, Metabolix is working with customers interested in achieving better performance with PLA biopolymers. Many of these customers are focused on developing a-PHA-modified PLA materials for sustainable, bio-based, and compostable packaging solutions. In addition to conducting numerous trials for transparent packaging films, Metabolix is working with customers interested in a-PHA-modified PLA for thermoformed transparent clamshells used in food service and consumer packaging as well as a-PHA-modified PLA for non-wovens used in personal care applications. MT Biobased and biodegradable thermoelastomers TerraVerdae BioWorks, Edmonton, Alberta, Canada, an industrial biotechnology company developing advanced bioplastics and biomaterials from environmentally sustainable, single-carbon (C1) feedstocks, has announced that it has entered into a strategic partnership agreement with PolyFerm, Kingston, Ontario, Canada. PolyFerm is a biopolymer company that is focused on developing renewable and biodegradable alternatives to petrochemicalbased elastomers. The partnership expands TerraVerdae’s product and technology portfolio into the high growth market of biodegradable thermoelastomers. PolyFerm has developed the only line of biodegradable thermoelastomers in the industry made entirely from renewable feedstocks. PolyFerm’s product line, marketed as VersaMer, is a medium-chain-length PHA material with enhanced elastomeric properties that can be engineered to multiple applications. This addresses a large unmet need within the biopolymer industry, with applications for adhesives and sealants, plastic additives, inks and toners, paints and coatings, and medical devices. “This strategic partnership allows us to offer our customers the most comprehensive product portfolio of high-value biodegradable polymers and opens up significant opportunities in new, highgrowth markets,” said William Bardosh, CEO and founder of TerraVerdae BioWorks. “ “With TerraVerdae, we have found an ideal partner to help us penetrate new markets with our high-performance polymer and elastomer products,” said Bruce Ramsay, Founder and CTO of PolyFerm Canada. “TerraVerdae’s demonstrated ability to scale up complex bioprocesses to meet the performance specifications demanded by industry is a great fit with our technology.” Elastomeric PHAs represent one of the most versatile classes of engineered materials for a number of commercial uses. These biodegradable materials combine the look, feel and elasticity of conventional thermoset rubber with improved processing efficiencies and are capable of withstanding large deformations while regaining their original shape. They also exhibit unique performance characteristics such as toughness, resilience, stretchability, and stiffness. KL | 22 bioplastics MAGAZINE [01/16] Vol. 11 © 2015 Honeywell International Inc.

WPCs, which require little maintenance have become popular replacements for solid wood. Common applications for these composites are in products such as decking, fences, railings and outdoor landscaping features. PVC is one of the key base polymers used in wood polymer composites for decking and railing systems. Miscibility between PVC and plasticizer is essential for good performance. PHA and PVC materials are highly miscible and moreover, have similar processing windows. Because of their miscibility with PVC, the PHA additives will not migrate out of the PVC and are easy to handle and process under the same conditions as PVC. Exploring the use of Metabolix I6003 PHAs in WPC, it was found that I6003, a multifunctional process aid, acted as an efficient fusion promoter, improved wood filler incorporation and dispersion, and significantly reduced torque in the extrude. Metabolix has worked with customers to develop new PVC-WPC formulations for decking and railing systems. Incorporating Metabolix PHA material into these formulations at a low loading level, made it possible to increase the proportion of wood flour used and at the same time to decrease the amount of PVC needed. The data generated by Metabolix showed that during processing, the addition of PHA, even at a low level, reduced torque and improved processing of the wood polymer composite material. For railing applications, the end-product also exhibited significantly improved mechanical properties and surface finish. This work demonstrates that PHA materials can offer significant performance benefits – and consequently costs advantages, as well – in PVC wood polymer composite systems. Brum said the company is looking forward to working with PVC wood polymer composite manufacturers to develop new solutions for decking and railing systems. KL | SEEING POLYMERS WITH DIFFERENT EYES...
