与会专家一致认为:与聚苯乙烯(PS)、聚氨酯(PU)、聚乙烯(PE)发泡材料相比,聚丙稀(PP)发泡材料开发的历史较短。然而,由于聚丙烯泡沫塑料具有优越的性能和广阔的应用前景,特别是市场对耐热性高、环保适性好的发泡材料需求迫切,使其发展迅速。目前几乎所有的世界著名的聚合物生产商都在进行研究开发。聚丙烯发泡材料在使用性能、成本以及其环境的影响方面具有独特的优势。 Participants agreed that polypropylene (PP) foams have a short history of development compared to polystyrene (PS), polyurethane (PU), and polyethylene (PE) foams. However, due to its superior properties and broad application prospects, polypropylene foam is particularly rapidly developing and is urgently needed in particular for foam materials which have high heat resistance and good environmental friendliness. At present, almost all of the world’s leading polymer manufacturers are conducting research and development. Polypropylene foams have unique advantages in terms of usability, cost and environmental impact.
