Effect of Recycling on the Cellular Structure of Polylactide in a Batch Process
The aim of the work is to demonstrate the possibility of using recycled biodegradable material as a cellular material with a reduced weight. An experimental study on the influence of recycling on the properties and foam ability of polylactide (PLA) was carried out. The influence of recycling on the polymer crystallinity, thermal and viscoelastic properties was investigated. During the batch process the cellular structure in PLA and recycled PLA were created. A higher degree of crystallinity, a lower viscosity value and a lower melt strength for recycled PLA, as compared to original material, were observed. For the recycled PLA, a fine cellular structure and low density (0.60 g/cm3) were obtained.
期刊介绍：
Cellular Polymers is concerned primarily with the science of foamed materials, the technology and state of the art for processing and fabricating, the engineering techniques and principles of the machines used to produce them economically, and their applications in varied and wide ranging uses where they are making an increasingly valuable contribution.
Potential problems for the industry are also covered, including fire performance of materials, CFC-replacement technology, recycling and environmental legislation. Reviews of technical and commercial advances in the manufacturing and application technologies are also included.
Cellular Polymers covers these and other related topics and also pays particular attention to the ways in which the science and technology of cellular polymers is being developed throughout the world.
