Poly Lactic Acid

by Rafael A. Auras, Poly Lactic Acid Books available in PDF, EPUB, Mobi Format. Download Poly Lactic Acid books, This book describes the synthesis, properties, and processing methods of poly(lactic acid) (PLA), an important family of degradable plastics. As the need for environmentally-friendly packaging materials increases, consumers and companies are in search for new materials that are largely produced from renewable resources, and are recyclable. To that end, an overall theme of the book is the biodegradability, recycling, and sustainability benefits of PLA. The chapters, from a base of international expert contributors, describe specific processing methods, spectroscopy techniques for PLA analysis, and and applications in medical items, packaging, and environmental use.

Polylactic Acid Production Cost Analysis Pla E11a

by Intratec, Polylactic Acid Production Cost Analysis Pla E11a Books available in PDF, EPUB, Mobi Format. Download Polylactic Acid Production Cost Analysis Pla E11a books, This report presents a cost analysis of Polylactic Acid (PLA) production from lactic acid using a melt-phase polymerization process. The process examined is similar to a process developed by Natureworks, in which poly(lactic acid) is produced from a 88 wt% lactic acid solution in water via the ring opening polymerization chemical pathway. In this process lactic acid is first oligomerized and then depolymerized into lactide, a cyclic dimer of lactic acid, which is then polymerized to yield Poly(lactic acid). This report was developed based essentially on the following reference(s): (1) US Patent 8674056, issued to NatureWorks in 2014 (2) EP Patent 1247808, issued to Cargill in 2003 Keywords: Lactide, 2-Hydroxypropanoic Acid, Dow, Biodegradable Polymer

by Intratec, Polylactic Acid Production From Raw Sugar Cost Analysis Pla E31b Books available in PDF, EPUB, Mobi Format. Download Polylactic Acid Production From Raw Sugar Cost Analysis Pla E31b books, This report presents a cost analysis of Polylactic Acid (PLA) production starting from raw sugar. The first section of the examined processis similar to Cargill process for lactic acid production, while the second section is similar to the NatureWorks process for polymerization of lactic acid. In this process, raw sugar (sucrose) is diluted and sucrose is hydrolyzed into glucose and fructose (invert sugars). The invert sugars are then fermented to produce lactic acid. Lactic Acid recovery from the fermentation broth is done by trialkylamine solvent extraction in the presence of carbon dioxide. An 88 wt% Lactic Acid solution in water is generated and further polymerized to form Polylactic Acid. This report was developed based essentially on the following reference(s): (1) US Patent 6472559, issued to Cargill in 2002 (2) US Patent 8674056, issued to NatureWorks in 2014 (3) EP Patent 1247808, issued to Cargill in 2003 Keywords: Dextrose, 2-Hydroxypropanoic Acid, Anaerobic Fermentation, Trialkyl Amine, Sodium Carbonate, Lactide, 2-Hydroxypropanoic Acid, Dow, Biodegradable Polymer

Download Plasticized Polylactic Acid Cellulose Nanocomposites Prepared Using Melt Extrusion And Liquid Feeding Mechanical Thermal And Optical Properties books, Abstract: Plasticized polylactic acid (PLA) and its nanocomposite based on cellulose nanofibers (CNF) and glycerol triacetate (GTA) were prepared using a co-rotating twin-screw extruder. GTA was used as a plasticizer, a processing aid to facilitate nanofiber dispersion and as a liquid medium for their feeding. The optical, thermal and mechanical properties were characterized and the toughening mechanism was studied. The addition of GTA (20%) and CNF (1%) resulted in increased degree of crystallinity and decreased optical transparency. Furthermore, these additives showed a positive effect on the elongation at break and toughness, which increased from 2% to 31% and from 1 to 8 MJ/m 3, respectively. The combination of slippage of the nanofiber–matrix interface and a massive crazing effect as a result of the presence of CNF is suggested for PLA toughening. CNF were expected to restrict the spherulite growth and therefore enhance the craze nucleation.

Download Boron Nitride Reinforced Polylactic Acid Composites Film For Packaging Preparation And Properties books, Abstract: Biopolymer composites obtained from renewable resources based polymers and inorganic materials are of potential interest owing to bioactivity, biodegradability and other superior properties. In the present study polylactic acid (PLA) samples containing 0-4wt% of ultrasonically exfoliated Boron Nitride (BN) were prepared by solvent casting method. To have an insight into the structure of the PLA/BN composites, phase morphologies were studied using Scanning Electron Microscopy (SEM). SEM images showed aggregation of BN at 4wt% of loading in the composite. Thermogravimetric analysis (TGA), Differential Scanning Calorimetry (DSC) and tensile testing were carried out to characterize the thermal and mechanical properties of the prepared composites. The optimum tensile strength of 28.5MPa was obtained for 2wt% of PLA/BN composite. This corresponds to an increase of about 132% as compared to PLA. Highlights: PLA/BN composite films were prepared by solvent casting method. Composites with 2wt % BN exhibited 132% increase in tensile strength. Enhanced Plasticity is obtained for the prepared composites. The prepared composite films are suitable for packaging applications.
