The Effect of Additives on Microcellular PVC Foams: Part 1 - Effect on Processing and Microstructure
The effect of the presence of commonly used additives on the processing and structure of microcellular PVC foams was investigated. It was found that the presence of additives leads to a polydisperse cell structure with large variations in cell sizes. The solubility of carbon dioxide in the additives and in the lubricants was found to be lower than in the PVC matrix. The presence of additives showed no adverse effect on the overall foam growth dynamics. It appears that target reductions in density of PVC can be achieved at lower processing temperatures when additives and processing aids are present.
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.
