Abstract

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.

添加剂对微孔聚氯乙烯泡沫的影响：第 1 部分 - 对加工和微观结构的影响

研究了常用添加剂的存在对微孔聚氯乙烯泡沫的加工和结构的影响。结果发现，添加剂的存在会导致多分散细胞结构，细胞大小变化很大。二氧化碳在添加剂和润滑剂中的溶解度低于在 PVC 基质中的溶解度。添加剂的存在对泡沫的整体生长动态没有不利影响。由此看来，当添加剂和加工助剂存在时，在较低的加工温度下也能达到降低聚氯乙烯密度的目标。

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.
